Weston +======================= + +Finding something to work on +---------------------------- + +Weston's development is [tracked on GitLab](https://gitlab.freedesktop.org/wayland/weston). +In addition to reviewing code submissions (see below), we use the issue tracker +to discuss both bugfixes and development of new features. + +The '[good for new contributors](https://gitlab.freedesktop.org/wayland/weston/issues?label_name%5B%5D=Good+for+new+contributors)' +label is used for issues the development team thinks are a good place to begin +working on Weston. These issues cover features or bugfixes which are small, +self-contained, don't require much specific background knowledge, and aren't +blocked by more complex work. + +If you have picked an issue you would like to work on, you may want to mention +in the issue tracker that you would like to pick it up. You can also discuss +it with the developers in the issue tracker, or on the +[mailing list](https://lists.freedesktop.org/mailman/listinfo/wayland-devel). +Many developers also use IRC through [Freenode](https://freenode.net)'s +`#wayland` channel; however you may need to wait some time for a response on +IRC, which requires keeping your client connected. If you cannot stay for a +long time (potentially some hours due to timezone differences), then you +may want to send your question to the list or issue tracker instead. + + +Sending patches +--------------- + +Patches should be sent via +[GitLab merge requests](https://docs.gitlab.com/ce/gitlab-basics/add-merge-request.html). +Weston is +[hosted on freedesktop.org's GitLab](https://gitlab.freedesktop.org/wayland/weston/): +in order to submit code, you should create an account on this GitLab instance, +fork the core Weston repository, push your changes to a branch in your new +repository, and then submit these patches for review through a merge request. + +Weston formerly accepted patches via `git-send-email`, sent to +**wayland-devel\@lists.freedesktop.org**; these were +[tracked using Patchwork](https://patchwork.freedesktop.org/projects/wayland/). +Some old patches continue to be sent this way, and we may accept small new +patches sent to the list, but please send all new patches through GitLab merge +requests. + +Formatting and separating commits +--------------------------------- + +Unlike many projects using GitHub and GitLab, Weston has a +[linear, 'recipe' style history](http://www.bitsnbites.eu/git-history-work-log-vs-recipe/). +This means that every commit should be small, digestible, stand-alone, and +functional. Rather than a purely chronological commit history like this: + + doc: final docs for view transforms + fix tests when disabled, redo broken doc formatting + better transformed-view iteration (thanks Hannah!) + try to catch more cases in tests + tests: add new spline test + fix compilation on splines + doc: notes on reticulating splines + compositor: add spline reticulation for view transforms + +we aim to have a clean history which only reflects the final state, broken up +into functional groupings: + + compositor: add spline reticulation for view transforms + compositor: new iterator for view transforms + tests: add view-transform correctness tests + doc: fix Doxygen formatting for view transforms + +This ensures that the final patch series only contains the final state, +without the changes and missteps taken along the development process. + +The first line of a commit message should contain a prefix indicating +what part is affected by the patch followed by one sentence that +describes the change. For examples: + + compositor-drm: Support modifiers for drm_fb + +and + + input: do not forward unmatched touch-ups + +If in doubt what prefix to use, look at other commits that change the +same file(s) as the patch being sent. + +The body of the commit message should describe what the patch changes +and why, and also note any particular side effects. This shouldn't be +empty on most of the cases. It shouldn't take a lot of effort to write +a commit message for an obvious change, so an empty commit message +body is only acceptable if the questions "What?" and "Why?" are already +answered on the one-line summary. + +The lines of the commit message should have at most 76 characters, to +cope with the way git log presents them. + +See [notes on commit messages] for a recommended reading on writing commit +messages. + +Your patches should also include a Signed-off-by line with your name and +email address which indicates that you agree to the +[Developer's Certificate of Origin 1.1](DCO-1.1.txt). +If you're not the patch's original author, you should +also gather S-o-b's by them (and/or whomever gave the patch to you.) The +significance of this is that it certifies that you created the patch, +that it was created under an appropriate open source license, or +provided to you under those terms. This lets us indicate a chain of +responsibility for the copyright status of the code. + +We won't reject patches that lack S-o-b, but it is strongly recommended. + +When you re-send patches, revised or not, it would be very good to document the +changes compared to the previous revision in the commit message and/or the +merge request. If you have already received Reviewed-by or Acked-by tags, you +should evaluate whether they still apply and include them in the respective +commit messages. Otherwise the tags may be lost, reviewers miss the credit they +deserve, and the patches may cause redundant review effort. + + +Tracking patches and following up +--------------------------------- + +Once submitted to GitLab, your patches will be reviewed by the Weston +development team on GitLab. Review may be entirely positive and result in your +code landing instantly, in which case, great! You're done. However, we may ask +you to make some revisions: fixing some bugs we've noticed, working to a +slightly different design, or adding documentation and tests. + +If you do get asked to revise the patches, please bear in mind the notes above. +You should use `git rebase -i` to make revisions, so that your patches follow +the clear linear split documented above. Following that split makes it easier +for reviewers to understand your work, and to verify that the code you're +submitting is correct. + +A common request is to split single large patch into multiple patches. This can +happen, for example, if when adding a new feature you notice a bug in Weston's +core which you need to fix to progress. Separating these changes into separate +commits will allow us to verify and land the bugfix quickly, pushing part of +your work for the good of everyone, whilst revision and discussion continues on +the larger feature part. It also allows us to direct you towards reviewers who +best understand the different areas you are working on. + +When you have made any requested changes, please rebase the commits, verify +that they still individually look good, then force-push your new branch to +GitLab. This will update the merge request and notify everyone subscribed to +your merge request, so they can review it again. + +There are also +[many GitLab CLI clients](https://about.gitlab.com/applications/#cli-clients), +if you prefer to avoid the web interface. It may be difficult to follow review +comments without using the web interface though, so we do recommend using this +to go through the review process, even if you use other clients to track the +list of available patches. + + +Coding style +------------ + +You should follow the style of the file you're editing. In general, we +try to follow the rules below. + +**Note: this file uses spaces due to markdown rendering issues for tabs. + Code must be indented using tabs.** + +- indent with tabs, and a tab is always 8 characters wide +- opening braces are on the same line as the if statement; +- no braces in an if-body with just one statement; +- if one of the branches of an if-else condition has braces, then the + other branch should also have braces; +- there is always an empty line between variable declarations and the + code; + +```c +static int +my_function(void) +{ + int a = 0; + + if (a) + b(); + else + c(); + + if (a) { + b(); + c(); + } else { + d(); + } +} +``` + +- lines should be less than 80 characters wide; +- when breaking lines with functions calls, the parameters are aligned + with the opening parentheses; +- when assigning a variable with the result of a function call, if the + line would be longer we break it around the equal '=' sign if it makes + sense; + +```c + long_variable_name = + function_with_a_really_long_name(parameter1, parameter2, + parameter3, parameter4); + + x = function_with_a_really_long_name(parameter1, parameter2, + parameter3, parameter4); +``` + +Conduct +======= + +As a freedesktop.org project, Wayland follows the Contributor Covenant, +found at: +https://www.freedesktop.org/wiki/CodeOfConduct + +Please conduct yourself in a respectful and civilised manner when +interacting with community members on mailing lists, IRC, or bug +trackers. The community represents the project as a whole, and abusive +or bullying behaviour is not tolerated by the project. + + +Licensing +========= + +Weston is licensed with the intention to be usable anywhere X.org is. +Originally, X.org was covered under the MIT X11 license, but changed to +the MIT Expat license. Similarly, Weston was covered initially as MIT +X11 licensed, but changed to the MIT Expat license, following in X.org's +footsteps. Other than wording, the two licenses are substantially the +same, with the exception of a no-advertising clause in X11 not included +in Expat. + +New source code files should specify the MIT Expat license in their +boilerplate, as part of the copyright statement. + + +Review +====== + +All patches, even trivial ones, require at least one positive review +(Reviewed-by). Additionally, if no Reviewed-by's have been given by +people with commit access, there needs to be at least one Acked-by from +someone with commit access. A person with commit access is expected to be +able to evaluate the patch with respect to the project scope and architecture. + +The below review guidelines are intended to be interpreted in spirit, not by +the letter. There may be circumstances where some guidelines are better +ignored. We rely very much on the judgement of reviewers and commit rights +holders. + +During review, the following matters should be checked: + +- The commit message explains why the change is being made. + +- The code fits the project's scope. + +- The code license is the same MIT licence the project generally uses. + +- Stable ABI or API is not broken. + +- Stable ABI or API additions must be justified by actual use cases, not only +by speculation. They must also be documented, and it is strongly recommended to +include tests exercising the additions in the test suite. + +- The code fits the existing software architecture, e.g. no layering +violations. + +- The code is correct and does not introduce new failures for existing users, +does not add new corner-case bugs, and does not introduce new compiler +warnings. + +- The patch does what it says in the commit message and changes nothing else. + +- The patch is a single logical change. If the commit message addresses +multiple points, it is a hint that the commit might need splitting up. + +- A bug fix should target the underlying root cause instead of hiding symptoms. +If a complete fix is not practical, partial fixes are acceptable if they come +with code comments and filed Gitlab issues for the remaining bugs. + +- The bug root cause rule applies to external software components as well, e.g. +do not work around kernel driver issues in userspace. + +- The test suite passes. + +- The code does not depend on API or ABI which has no working free open source +implementation. + +- The code is not dead or untestable. E.g. if there are no free open source +software users for it then it is effectively dead code. + +- The code is written to be easy to understand, or if code cannot be clear +enough on its own there are code comments to explain it. + +- The code is minimal, i.e. prefer refactor and re-use when possible unless +clarity suffers. + +- The code adheres to the style guidelines. + +- In a patch series, every intermediate step adheres to the above guidelines. + + +Commit rights +============= + +Commit rights will be granted to anyone who requests them and fulfills the +below criteria: + +- Submitted some (10 as a rule of thumb) non-trivial (not just simple + spelling fixes and whitespace adjustment) patches that have been merged + already. + +- Are actively participating in public discussions about their work (on the + mailing list or IRC). This should not be interpreted as a requirement to + review other peoples patches but just make sure that patch submission isn't + one-way communication. Cross-review is still highly encouraged. + +- Will be regularly contributing further patches. This includes regular + contributors to other parts of the open source graphics stack who only + do the occasional development in this project. + +- Agrees to use their commit rights in accordance with the documented merge + criteria, tools, and processes. + +To apply for commit rights, create a new issue in gitlab for the respective +project and give it the "accounts" label. + +Committers are encouraged to request their commit rights get removed when they +no longer contribute to the project. Commit rights will be reinstated when they +come back to the project. + +Maintainers and committers should encourage contributors to request commit +rights, especially junior contributors tend to underestimate their skills. + + +Stabilising for releases +======================== + +A release cycle ends with a stable release which also starts a new cycle and +lifts any code freezes. Gradual code freezing towards a stable release starts +with an alpha release. The release stages of a cycle are: + +- **Alpha release**: + Signified by version number #.#.91. + Major features must have landed before this. Major features include + invasive code motion and refactoring, high risk changes, and new stable + library ABI. + +- **Beta release**: + Signified by version number #.#.92. + Minor features must have landed before this. Minor features include all + new features that are not major, low risk changes, clean-ups, and + documentation. Stable ABI that was new in the alpha release can be removed + before a beta release if necessary. + +- **Release candidates (RC)**: + Signified by version number #.#.93 and up to #.#.99. + Bug fixes that are not release critical must have landed before this. + Release critical bug fixes can still be landed after this, but they may + call for another RC. + +- **Stable release**: + Signified by version number #.#.0. + Ideally no changes since the last RC. + +Mind that version #.#.90 is never released. It is used during development when +no code freeze is in effect. Stable branches and point releases are not covered +by the above. + + +[git documentation]: http://git-scm.com/documentation +[notes on commit messages]: http://who-t.blogspot.de/2009/12/on-commit-messages.html diff --git a/COPYING b/COPYING new file mode 100644 index 0000000..fa4a8c4 --- /dev/null +++ b/COPYING @@ -0,0 +1,26 @@ + + +Permission is hereby granted, free of charge, to any person obtaining a +copy of this software and associated documentation files (the "Software"), +to deal in the Software without restriction, including without limitation +the rights to use, copy, modify, merge, publish, distribute, sublicense, +and/or sell copies of the Software, and to permit persons to whom the +Software is furnished to do so, subject to the following conditions: + +The above copyright notice and this permission notice (including the next +paragraph) shall be included in all copies or substantial portions of the +Software. + +THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR +IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, +FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

This +will launch Weston inside whatever environment you launch it from: when launched +from a text console, it will take over that console. When launched from inside +an existing Wayland or X11 session, it will start a 'nested' instance of Weston +inside a window in that session. + +Help is available by running `weston --help`, or `man weston`, which will list +the available configuration options and display backends. It can also be +configured through a file on disk; more information on this can be found through +`man weston.ini`. + +In some special cases, such as when running remotely or without logind's session +control, Weston may not be able to run directly from a text console. In these +situations, you can instead execute the `weston-launch` helper, which will gain +privileged access to input and output devices by running as root, then granting +access to the main Weston binary running as your user. Running Weston this way +is not recommended unless necessary. + +Weston-doc +========== + +For documenting weston we use [sphinx](http://www.sphinx-doc.org/en/master/) +together with [breathe](https://breathe.readthedocs.io/en/latest/) that +understands XMLs databases generated by doxygen. So far, this is a compromise +until better tools are available in order to remove the doxygen +dependency. You should be able to install both sphinx and breathe extension +using pip3 command, or your package manager. +Doxygen should be available using your distribution package manager. + +Once those are set-up, run `meson` with `-Ddoc=true` option in order to enable +building the documentation. Installation will place the documentation in the +prefix's path under datadir (i.e., `share/doc`). + +Adding and improving documentation +---------------------------------- + +For re-generating the documentation a special `docs` target has been added. +Although first time you build (and subsequently install) weston, you'll see the +documentation being built, updates to the spinx documentation files or to the +source files will only be updated when using `docs` target! + +Example: + +~~~~ +$ ninja install # generates and installs the documentation +# time passes, hack hack, add doc in sources or rST files +$ ninja install # not sufficient, docs will not be updated +$ ninja docs && ninja install # run 'docs' then install +~~~~ + +Improving/adding documentation can be done by modifying rST files under +`doc/sphinx/` directory or by modifying the source code using doxygen +directives. + +Libweston +========= + +Libweston is an effort to separate the re-usable parts of Weston into +a library. Libweston provides most of the boring and tedious bits of +correctly implementing core Wayland protocols and interfacing with +input and output systems, so that people who just want to write a new +"Wayland window manager" (WM) or a small desktop environment (DE) can +focus on the WM part. + +Libweston was first introduced in Weston 1.12, and is expected to +continue evolving through many Weston releases before it achieves a +stable API and feature completeness. + +Libweston's primary purpose is exporting an API for creating Wayland +compositors. Libweston's secondary purpose is to export the weston_config API +so that third party plugins and helper programs can read `weston.ini` if they +want to. However, these two scopes are orthogonal and independent. At no point +will the compositor functionality use or depend on the weston_config +functionality. + + +API/ABI (in)stability and parallel installability +------------------------------------------------- + +As libweston's API surface is huge, it is impossible to get it right +in one go. Therefore developers reserve the right to break the API/ABI and bump +the major version to signify that. For git snapshots of the master branch, the +API/ABI can break any time without warning. + +Libweston major can be bumped only once during a development cycle. This should +happen on the first patch that breaks the API or ABI. Further breaks before the +next Weston major.0.0 release do not cause a bump. This means that libweston +API and ABI are allowed to break also after an alpha release, up to the final +release. However, breaks after alpha should be judged by the usual practices +for allowing minor features, fixes only, or critical fixes only. + +To make things tolerable for libweston users despite API/ABI breakages, +different libweston major versions are designed to be perfectly +parallel-installable. This way external projects can easily depend on a +particular API/ABI-version. Thus they do not have to fight over which +ABI-version is installed in a user's system. This allows a user to install many +different compositors each requiring a different libweston ABI-version without +tricks or conflicts. + +Note, that versions of Weston itself will not be parallel-installable, +only libweston is. + +For more information about parallel installability, see +http://ometer.com/parallel.html + + +Versioning scheme +----------------- + +In order to provide consistent, easy to use versioning, libweston +follows the rules in the Apache Portable Runtime Project +http://apr.apache.org/versioning.html. + +The document provides the full details, with the gist summed below: + - Major - backward incompatible changes. + - Minor - new backward compatible features. + - Patch - internal (implementation specific) fixes. + +Weston and libweston have separate version numbers in meson.build. All +releases are made by the Weston version number. Libweston version number +matches the Weston version number in all releases except maybe pre-releases. +Pre-releases have the Weston micro version 91 or greater. + +A pre-release is allowed to install a libweston version greater than the Weston +version in case libweston major was bumped. In that case, the libweston version +must be Weston major + 1. + +Pkg-config files are named after libweston major, but carry the Weston version +number. This means that Weston pre-release 2.1.91 may install libweston-3.pc +for the future libweston 3.0.0, but the .pc file says the version is still +2.1.91. When a libweston user wants to depend on the fully stable API and ABI +of a libweston major, he should use (e.g. for major 3): + + PKG_CHECK_MODULES(LIBWESTON, [libweston-3 >= 3.0.0]) + +Depending only on libweston-3 without a specific version number still allows +pre-releases which might have different API or ABI. + + +Forward compatibility +--------------------- + +Inspired by ATK, Qt and KDE programs/libraries, libjpeg-turbo, GDK, +NetworkManager, js17, lz4 and many others, libweston uses a macro to restrict +the API visible to the developer - REQUIRE_LIBWESTON_API_VERSION. + +Note that different projects focus on different aspects - upper and/or lower +version check, default to visible/hidden old/new symbols and so on. + +libweston aims to guard all newly introduced API, in order to prevent subtle +breaks that a simple recompile (against a newer version) might cause. + +The macro is of the format 0x$MAJOR$MINOR and does not include PATCH version. +As mentioned in the Versioning scheme section, the latter does not reflect any +user visible API changes, thus should be not considered part of the API version. + +All new symbols should be guarded by the macro like the example given below: + +~~~~ +#if REQUIRE_LIBWESTON_API_VERSION >= 0x0101 + +bool +weston_ham_sandwich(void); + +#endif +~~~~ + +In order to use the said symbol, the one will have a similar code in their +configure.ac: + +~~~~ +PKG_CHECK_MODULES(LIBWESTON, [libweston-1 >= 1.1]) +AC_DEFINE(REQUIRE_LIBWESTON_API_VERSION, [0x0101]) +~~~~ + +If the user is _not_ interested in forward compatibility, they can use 0xffff +or similar high value. Yet doing so is not recommended. + + +Libweston design goals +---------------------- + +The high-level goal of libweston is to decouple the compositor from +the shell implementation (what used to be shell plugins). + +Thus, instead of launching 'weston' with various arguments to choose the +shell, one would launch the shell itself, e.g. 'weston-desktop', +'weston-ivi', 'orbital', etc. The main executable (the hosting program) +will implement the shell, while libweston will be used for a fundamental +compositor implementation. + +Libweston is also intended for use by other project developers who want +to create new "Wayland WMs". + +Details: + +- All configuration and user interfaces will be outside of libweston. + This includes command line parsing, configuration files, and runtime + (graphical) UI. + +- The hosting program (main executable) will be in full control of all + libweston options. Libweston should not have user settable options + that would work behind the hosting program's back, except perhaps + debugging features and such. + +- Signal handling will be outside of libweston. + +- Child process execution and management will be outside of libweston. + +- The different backends (drm, fbdev, x11, etc) will be an internal + detail of libweston. Libweston will not support third party + backends. However, hosting programs need to handle + backend-specific configuration due to differences in behaviour and + available features. + +- Renderers will be libweston internal details too, though again the + hosting program may affect the choice of renderer if the backend + allows, and maybe set renderer-specific options. + +- plugin design ??? + +- xwayland ??? + +- weston-launch is still with libweston even though it can only launch + Weston and nothing else. We would like to allow it to launch any compositor, + but since it gives by design root access to input devices and DRM, how can + we restrict it to intended programs? + +There are still many more details to be decided. + + +For packagers +------------- + +Always build Weston with --with-cairo=image. + +The Weston project is (will be) intended to be split into several +binary packages, each with its own dependencies. The maximal split +would be roughly like this: + +- libweston (minimal dependencies): + + headless backend + + wayland backend + +- gl-renderer (depends on GL libs etc.) + +- drm-backend (depends on libdrm, libgbm, libudev, libinput, ...) + +- x11-backend (depends of X11/xcb libs) + +- xwayland (depends on X11/xcb libs) + +- fbdev-backend (depends on libudev...) + +- rdp-backend (depends on freerdp) + +- weston (the executable, not parallel-installable): + + desktop shell + + ivi-shell + + fullscreen shell + + weston-info (deprecated), weston-terminal, etc. we install by default + + screen-share + +- weston demos (not parallel-installable) + + weston-simple-* programs + + possibly all the programs we build but do not install by + default + +- and possibly more... + +Everything should be parallel-installable across libweston major +ABI-versions (libweston-1.so, libweston-2.so, etc.), except those +explicitly mentioned. + +Weston's build may not sanely allow this yet, but this is the +intention. diff --git a/clients/calibrator.c b/clients/calibrator.c new file mode 100644 index 0000000..21ca876 --- /dev/null +++ b/clients/calibrator.c @@ -0,0 +1,311 @@ +/* + * Copyright © 2012 Intel Corporation + * + * Permission is hereby granted, free of charge, to any person obtaining a + * copy of this software and associated documentation files (the "Software"), + * to deal in the Software without restriction, including without limitation + * the rights to use, copy, modify, merge, publish, distribute, sublicense, + * and/or sell copies of the Software, and to permit persons to whom the + * Software is furnished to do so, subject to the following conditions: + * + * The above copyright notice and this permission notice (including the next + * paragraph) shall be included in all copies or substantial portions of the + * Software. + * + * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR + * IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, + * FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

Full-screen surfaces will be +scanned out directly without compositing, when possible. +Hardware accelerated clients are supported via EGL. + +The backend chooses the DRM graphics device first based on seat id. +If seat identifiers are not set, it looks for the graphics device +that was used in boot. If that is not found, it finally chooses +the first DRM device returned by +.BR udev (7). +Combining multiple graphics devices is not supported yet. + +The DRM backend relies on +.B weston-launch +for managing input device access and DRM master status, so that +.B weston +can be run without root privileges. On switching away from the +virtual terminal (VT) hosting Weston, all input devices are closed and +the DRM master capability is dropped, so that other servers, +including +.BR Xorg (1), +can run on other VTs. On switching back to Weston's VT, input devices +and DRM master are re-acquired through the parent process +.BR weston-launch . + +The DRM backend also supports virtual outputs that are transmitted over +an RTP session as a series of JPEG images (RTP payload type 26) to a remote +client. Virtual outputs are configured in the +.BR remote-output +section of +.BR weston.ini. +. +.\" *************************************************************** +.SH CONFIGURATION +. +The DRM backend uses the following entries from +.BR weston.ini . +.SS Section output +.TP +\fBname\fR=\fIconnector\fR +The KMS connector name identifying the output, for instance +.IR LVDS1 . +.TP +\fBmode\fR=\fImode\fR +Specify the video mode for the output. The argument +.I mode +can be one of the words +.BR off " to turn the output off, " +.BR preferred " to use the monitor's preferred video mode, or " +.BR current " to use the current video mode and avoid a mode switch." +It can also be a resolution as: +.TP +\fBmode\fR=\fIwidth\fBx\fIheight\fR +.TP +\fBmode\fR=\fIwidth\fBx\fIheight\fB@\fIrefresh_rate\fR +Specify a mode with a given refresh-rate measured in Hz. +.TP +\fBmode\fR=\fIwidth\fBx\fIheight\fB@\fIrefresh_rate ratio\fR +Here \fIratio\fR is Picture Aspect-Ratio which can have values as 4:3, 16:9, +64:27, and 256:135. This resolution-format helps to select a CEA mode, if such a +video mode is present in the mode-list of the output. + +CEA defines the timing of a video mode, which is considered as a standard for +HDMI spcification and compliance testing. It defines each and every parameter of +a video mode, like hactive, vactive, vfront, vback etc., including aspect-ratio +information. For CEA modes, the drm layer, stores this aspect-ratio information +in user-mode (drmModeModeInfo) flag bits 19-22. For the non-CEA modes a value of +0 is stored in the aspect-ratio flag bits. + +Each CEA-mode is identified by a unique, Video Identification Code (VIC). +For example, VIC=4 is 1280x720@60 aspect-ratio 16:9. This mode will be +different than a non-CEA mode 1280x720@60 0:0. When the video mode +1280x720@60 0:0 is applied, since its timing doesn't exactly match with the CEA +information for VIC=4, it would be treated as a non-CEA mode. Also, while setting +the HDMI-AVI-Inforframe, VIC parameter will be given as '0'. If video mode +1280x720@60 16:9 is applied, its CEA timimgs matches with that of video mode with +VIC=4, so the VIC parameter in HDMI-AVI-Infoframe will be set to 4. + +Many a times, an output may have both CEA and non-CEA modes, which are similar +in all resepct, differing only in the aspect-ratio. A user can select a CEA mode +by giving the aspect-ratio, along with the other arguments for the mode. +By omitting the aspect-ratio, user can specify the non-CEA modes. +This helps when certification testing is done, in tests like 7-27, the +HDMI-analyzer applies a particular CEA mode, and expects the applied mode to be +with exactly same timings, including the aspect-ratio and VIC field. + +The resolution can also be a detailed mode line as below. +.TP +\fBmode\fR=\fIdotclock hdisp hsyncstart hsyncend htotal \ +vdisp vsyncstart vsyncend vtotal hflag vflag\fR +Use the given detailed mode line as the video mode for this output. +The definition is the same as in +.BR xorg.conf "(5), and " cvt (1) +can generate detailed mode lines. +.TP +\fBtransform\fR=\fItransform\fR +Transform for the output, which can be rotated in 90-degree steps +and possibly flipped.

A Wayland server is a +display server, a window manager, and a compositor all in one. Weston has +several backends as loadable modules: it can run on Linux KMS (kernel +modesetting via DRM), as an X client, or inside another Wayland server +instance. + +Weston supports fundamentally different graphical user interface paradigms via +shell plugins. Two plugins are provided: the desktop shell, and the tablet +shell. + +When weston is started as the first windowing system (i.e. not under X nor +under another Wayland server), it should be done with the command +.B weston-launch +to set up proper privileged access to devices. If your system supports +the logind D-Bus API and the support has been built into weston as well, +it is possible to start weston with just +.BR weston . + +Weston also supports X clients via +.BR XWayland ", see below." +. +.\" *************************************************************** +.SH BACKENDS +.TP +.I drm-backend.so +The DRM backend uses Linux KMS for output and evdev devices for input. +It supports multiple monitors in a unified desktop with DPMS. See +.BR weston-drm (7), +if installed. +.TP +.I wayland-backend.so +The Wayland backend runs on another Wayland server, a different Weston +instance, for example. Weston shows up as a single desktop window on +the parent server. +.TP +.I x11-backend.so +The X11 backend runs on an X server. Each Weston output becomes an +X window. This is a cheap way to test multi-monitor support of a +Wayland shell, desktop, or applications. +.TP +.I rdp-backend.so +The RDP backend runs in memory without the need of graphical hardware. Access +to the desktop is done by using the RDP protocol. Each connecting +client has its own seat making it a cheap way to test multi-seat support. See +.BR weston-rdp (7), +if installed. +. +.\" *************************************************************** +.SH SHELLS +Each of these shells have its own public protocol interface for clients. +This means that a client must be specifically written for a shell protocol, +otherwise it will not work. +.TP +Desktop shell +Desktop shell is like a modern X desktop environment, concentrating +on traditional keyboard and mouse user interfaces and the familiar +desktop-like window management. Desktop shell consists of the +shell plugin +.I desktop-shell.so +and the special client +.B weston-desktop-shell +which provides the wallpaper, panel, and screen locking dialog. +.TP +Fullscreen shell +Fullscreen shell is intended for a client that needs to take over +whole outputs, often all outputs. This is primarily intended for +running another compositor on Weston. The other compositor does not +need to handle any platform-specifics like DRM/KMS or evdev/libinput. +The shell consists only of the shell plugin +.IR fullscreen-shell.so . +.TP +IVI-shell +In-vehicle infotainment shell is a special purpose shell that exposes +a GENIVI Layer Manager compatible API to controller modules, and a very +simple shell protocol towards clients. IVI-shell starts with loading +.IR ivi-shell.so , +and then a controller module which may launch helper clients. +. +.\" *************************************************************** +.SH XWAYLAND +XWayland requires a special X.org server to be installed. This X server will +connect to a Wayland server as a Wayland client, and X clients will connect to +the X server. XWayland provides backwards compatibility to X applications in a +Wayland stack. + +XWayland is activated by instructing +.BR weston " to load the XWayland module, see " EXAMPLES . +Weston starts listening on a new X display socket, and exports it in the +environment variable +.BR DISPLAY . +When the first X client connects, Weston launches a special X server as a +Wayland client to handle the X client and all future X clients. + +It has also its own X window manager where cursor themes and sizes can be +chosen using +.BR XCURSOR_PATH +and +.BR XCURSOR_SIZE " environment variables. See " ENVIRONMENT . +. +.\" *************************************************************** +.SH OPTIONS +. +.SS Weston core options: +.TP +\fB\-\^B\fR\fIbackend.so\fR, \fB\-\-backend\fR=\fIbackend.so\fR +Load +.I backend.so +instead of the default backend. The file is searched for in +.IR "@weston_modules_dir@" , +or you can pass an absolute path.

First, a client may cause a denial-of-service +blocking the compositor by providing an unsuitable file descriptor, and +second, the debug messages may expose sensitive information. +Additionally this will expose weston-screenshooter interface allowing the user +to take screenshots of the outputs using weston-screenshooter application, +which can lead to silently leaking the output contents. This option should +not be used in production. +.TP +\fB\-\^l\fIscope1,scope2\fR, \fB\-\-logger-scopes\fR=\fIscope1,scope2\fR +Specify to which log scopes should subscribe to.

The default timeout is 300 seconds. When there has not been any +user input for the idle timeout, Weston enters an inactive mode. The +screen fades to black, monitors may switch off, and the shell may lock +the session. +A value of 0 effectively disables the timeout. +.TP +\fB\-\-log\fR=\fIfile.log\fR +Append log messages to the file +.I file.log +instead of writing them to stderr. +.TP +\fB\-\-xwayland\fR +Ask Weston to load the XWayland module. +.TP +\fB\-\-modules\fR=\fImodule1.so,module2.so\fR +Load the comma-separated list of modules.

A quick way to get +started, is to fork Weston's desktop-shell plugin and start hacking it. +Qt could be another good choice, but I am not familiar with it. + +You also need to understand some concepts. I'm repeating things I wrote +to the wayland-devel list earlier, a little rephrased. + +We need to distinguish three different things here (towards Wayland +clients): + +- compositors (servers) + All Wayland compositors are indistinguishable by definition, + since they are Wayland compositors. They only differ in the + global interfaces they advertise, and for general purpose + compositors, we should aim to support the same minimum set of + globals everywhere. For instance, all desktop compositors + should implement wl_shell. In X, this component corresponds to + the X server with a built-in compositing manager. + +- shells + This is a new concept compared to an X stack. A shell defines + how a user and applications interact. The most familiar is a + desktop (environment). If KDE, Gnome, and XFCE are desktop + environments, they all fall under the *same* shell: the desktop + shell. You can have applications in windows, several visible at + the same time, you have keyboards and mice, etc. + + An example of something that is not a desktop shell + could be a TV user interface. TV is profoundly different: + usually no mouse, no keyboard, but you have a remote control + with some buttons. Freely floating windows probably do not make + sense. You may have picture-in-picture, but usually not several + applications showing at once. Most importantly, trying to run + desktop applications here does not work due to the + incompatible application and user interface paradigms. + + On protocol level, a shell is the public shell interface(s), + currently for desktop it is the wl_shell. + +- "window managers" + The X Window Managers correspond to different wl_shell + implementations, not different shells, since they practically + all deal with a desktop environment. You also want all desktop + applications to work with all window managers, so you need to + implement wl_shell anyway. + +I understand there could be special purpose X Window Managers, that +would better correspond to their own shells. These window managers +might not implement e.g. EWMH by the spec. + +When you implement your own window manager, you want to keep the public +desktop shell interface (wl_shell). You can offer new public +interfaces, too, but keep in mind, that someone needs to make +applications use them. + +In Weston, a shell implementation has two parts: a weston plugin, and a +special client. For desktop shell (wl_shell) these are src/shell.c and +clients/desktop-shell.c. The is also a private protocol extension that +these two can explicitly communicate with. + +The plugin does window management, and the client does most of user +interaction: draw backgrounds, panels, buttons, lock screen dialog, +basically everything that is on screen. + +----------------------------------------------------------------------- diff --git a/pipewire/meson.build b/pipewire/meson.build new file mode 100644 index 0000000..3d3374b --- /dev/null +++ b/pipewire/meson.build @@ -0,0 +1,31 @@ +if get_option('pipewire') + user_hint = 'If you rather not build this, set "pipewire=false".' + + if not get_option('backend-drm') + error('Attempting to build the pipewire plugin without the required DRM backend.

Client applications should not wait for the protection + to change, as it might never change in case the content-protection cannot be + achieved. Alternatively, clients can use a timeout and start showing the + content in lower quality. + + Censored visibility is defined as the compositor censoring the protected + content on non-secure outputs. Censoring may include artificially reducing + image quality or replacing the protected content completely with + placeholder graphics. + + Censored visibility is controlled by protection mode, set by the client. + In "relax" mode, the compositor may show protected content on non-secure + outputs. It will be up to the client to adapt to secure and non-secure + presentation. In "enforce" mode, the compositor will censor the parts of + protected content that would otherwise show on non-secure outputs. + + + + + The global interface weston_content_protection is used for exposing the + content protection capabilities to a client. It provides a way for clients + to request their wl_surface contents to not be displayed on an output + below their required level of content-protection. + Using this interface clients can request for a weston_protected_surface + which is an extension to the wl_surface to provide content-protection, and + set the censored-visibility on the non-secured-outputs. + + + + + Informs the server that the client will not be using this + protocol object anymore. This does not affect any other objects, + protected_surface objects included. + + + + + + + + + + Instantiate an interface extension for the given wl_surface to + provide surface protection.

Updates to this status are sent to the client + via the 'status' event. Before the first status event is sent, the client + should assume that the status is 'unprotected'. + + A client can request a content protection level to be the minimum for an + output to be considered secure, using the 'set_type' request. + It is responsibility of the client to monitor the actual + content-protection level achieved via the 'status' event, and make + decisions as to what content to show based on this. + + The server should make its best effort to achieve the desired + content-protection level on all of the outputs the client's contents are + being displayed on. Any changes to the content protection status should be + reported to the client, even if they are below the requested + content-protection level. If the client's contents are being displayed on + multiple outputs, the lowest content protection level achieved should be + reported. + + A client can also request that its content only be displayed on outputs + that are considered secure. The 'enforce/relax' requests can achieve this. + In enforce mode, the content is censored for non-secure outputs. + The implementation of censored-visibility is compositor-defined. + In relax mode there are no such limitation. On an attempt to show the + client on unsecured output, compositor would keep on showing the content + and send the 'status' event to the client.

The intention is that a client uses this + request to convert marker positions that the user is supposed to touch + during calibration. + + If the compositor has cancelled the calibration, the conversion result + shall be zeroes and no errors will be raised. + + The coordinates given as arguments to this request are relative to + the associated wl_surface. + + If a client asks for conversion before it has committed valid + content to the wl_surface, the not_mapped error is raised. + + If the coordinates x, y are outside of the wl_surface content, the + bad_coordinates error is raised. + + + + + + + + + This event tells the client what size to make the surface. The client + must obey the size exactly on the next commit with a wl_buffer. + + This event shall be sent once as a response to creating a + weston_touch_calibrator object. + + + + + + + + This is sent when the compositor wants to cancel the calibration and + drop the touch device grab. The compositor unmaps the surface, if it + was mapped. + + The weston_touch_calibrator object will not send any more events. The + client should destroy it. + + + + + + For whatever reason, a touch event resulting from a user action cannot + be used for calibration. The client should show feedback to the user + that the touch was rejected. + + Possible causes for this event include the user touching a wrong + touchscreen when there are multiple ones present. This is particularly + useful when the touchscreens are cloned and there is no other way to + identify which screen the user should be touching. + + Another cause could be a touch device that sends coordinates beyond its + declared range. If motion takes a touch point outside the range, the + compositor should also send 'cancel' event to undo the touch-down. + + + + + + + A new touch point has appeared on the surface. This touch point is + assigned a unique ID. Future events from this touch point reference + this ID. The ID ceases to be valid after a touch up event and may be + reused in the future. + + For the coordinate units, see weston_touch_calibrator. + + + + + + + + + + The touch point has disappeared. No further events will be sent for + this touch point and the touch point's ID is released and may be + reused in a future touch down event. + + + + + + + + A touch point has changed coordinates. + + For the coordinate units, see weston_touch_calibrator. + + + + + + + + + + Indicates the end of a set of events that logically belong together. + A client is expected to accumulate the data in all events within the + frame before proceeding. + + A wl_touch.frame terminates at least one event but otherwise no + guarantee is provided about the set of events within a frame. A client + must assume that any state not updated in a frame is unchanged from the + previously known state. + + + + + + Sent if the compositor decides the touch stream is a global + gesture. No further events are sent to the clients from that + particular gesture. Touch cancellation applies to all touch points + currently active on this client's surface. The client is + responsible for finalizing the touch points, future touch points on + this surface may reuse the touch point ID. + + + + + + + + + + + + + + This event returns the conversion result from surface coordinates to + the expected touch device coordinates. + + For details, see weston_touch_calibrator.convert. For the coordinate + units, see weston_touch_calibrator. + + This event destroys the weston_touch_coordinate object. + + + + + + diff --git a/releasing.md b/releasing.md new file mode 100644 index 0000000..1864dc3 --- /dev/null +++ b/releasing.md @@ -0,0 +1,72 @@ +# Releasing + +To make a release of Weston, follow these steps. + +0.

The structure of the test code and macro use is intended to +follow common patterns established by frameworks such as Boost Test and Google +Test. + + +To get started, one or more tests should be defined via ZUC_TEST() and/or +ZUC_TEST_F(), which set up automatic test registration via gcc extensions. +To actually execute tests, ZUC_RUN_TESTS() should be called. + + +Tests can use several ZUC_ASSERT_* or ZUC_ASSERTG_* checks to validate +conditions.

It's a variable framerate +format, that only records new frames along with a timestamp when +something actually changes. + +Recording in Weston is started by pressing MOD+R and stopped by +pressing MOD+R again. Currently this leaves a capture.wcap file in +the cwd of the weston process. The file format is documented below +and Weston comes with the wcap-decode tool to convert the wcap file +into something more usable: + + - Extract single or all frames as individual png files. This will + produce a lossless screenshot, which is useful if you're trying to + screenshot a brief glitch or something like that that's hard to + capture with the screenshot tool. + + wcap-decode takes a number of options and a wcap file as its + arguments. Without anything else, it will show the screen size and + number of frames in the file. Pass --frame= to extract a + single frame or pass --all to extract all frames as png files: + + [krh@minato weston]$ wcap-snapshot capture.wcap + wcap file: size 1024x640, 176 frames + [krh@minato weston]$ wcap-snapshot capture.wcap 20 + wrote wcap-frame-20.png + wcap file: size 1024x640, 176 frames + + - Decode and the wcap file and dump it as a YUV4MPEG2 stream on + stdout. This format is compatible with most video encoders and can + be piped directly into a command line encoder such as vpxenc (part + of libvpx, encodes to a webm file) or theora_encode (part of + libtheora, encodes to a ogg theora file). + + Using vpxenc to encode a webm file would look something like this: + + [krh@minato weston]$ wcap-decode --yuv4mpeg2 ../capture.wcap | + vpxenc --target-bitrate=1024 --best -t 4 -o foo.webm - + + where we select target bitrate, pass -t 4 to let vpxenc use + multiple threads. To encode to Ogg Theora a command line like this + works: + + [krh@minato weston]$ wcap-decode ../capture.wcap --yuv4mpeg2 | + theora_encode - -o cap.ogv + + +WCAP File format + +The file format has a small header and then just consists of the +individual frames. The header is + + uint32_t magic + uint32_t format + uint32_t width + uint32_t height + +all CPU endian 32 bit words. The magic number is + + #define WCAP_HEADER_MAGIC 0x57434150 + +and makes it easy to recognize a wcap file and verify that it's the +right endian. There are four supported pixel formats: + + #define WCAP_FORMAT_XRGB8888 0x34325258 + #define WCAP_FORMAT_XBGR8888 0x34324258 + #define WCAP_FORMAT_RGBX8888 0x34325852 + #define WCAP_FORMAT_BGRX8888 0x34325842 + +Each frame has a header: + + uint32_t msecs + uint32_t nrects + +which specifies a timestamp in ms and the number of rectangles that +changed since previous frame. The timestamps are typically just a raw +system timestamp and the first frame doesn't start from 0ms. + +A frame consists of a list of rectangles, each of which represents the +component-wise difference between the previous frame and the current +using a run-length encoding. The initial frame is decoded against a +previous frame of all 0x00000000 pixels. Each rectangle starts out +with + + int32_t x1 + int32_t y1 + int32_t x2 + int32_t y2 + +followed by (x2 - x1) * (y2 - y1) pixels, run-length encoded. The +run-length encoding uses the 'X' channel in the pixel format to encode +the length of the run. That is for WCAP_FORMAT_XRGB8888, for example, +the length of the run is in the upper 8 bits. For X values 0-0xdf, +the length is X + 1, for X above or equal to 0xe0, the run length is 1 +<< (X - 0xe0 + 7). That is, a pixel value of 0xe3000100, means that +the next 1024 pixels differ by RGB(0x00, 0x01, 0x00) from the previous +pixels. diff --git a/wcap/main.c b/wcap/main.c new file mode 100644 index 0000000..7eba6d6 --- /dev/null +++ b/wcap/main.c @@ -0,0 +1,331 @@ +2021-222222 + MIT License + +Copyright (c) 2021 Jianhui Zhao + +Permission is hereby granted, free of charge, to any person obtaining a copy +of this software and associated documentation files (the "Software"), to deal +in the Software without restriction, including without limitation the rights +to use, copy, modify, merge, publish, distribute, sublicense, and/or sell +copies of the Software, and to permit persons to whom the Software is +furnished to do so, subject to the following conditions: + +The above copyright notice and this permission notice shall be included in all +copies or substantial portions of the Software. + +THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR +IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, +FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

By contrast, +the GNU General Public License is intended to guarantee your freedom to +share and change all versions of a program--to make sure it remains free +software for all its users. We, the Free Software Foundation, use the +GNU General Public License for most of our software; it applies also to +any other work released this way by its authors. You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +them if you wish), that you receive source code or can get it if you +want it, that you can change the software or use pieces of it in new +free programs, and that you know you can do these things. + + To protect your rights, we need to prevent others from denying you +these rights or asking you to surrender the rights. Therefore, you have +certain responsibilities if you distribute copies of the software, or if +you modify it: responsibilities to respect the freedom of others. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must pass on to the recipients the same +freedoms that you received. You must make sure that they, too, receive +or can get the source code. And you must show them these terms so they +know their rights. + + Developers that use the GNU GPL protect your rights with two steps: +(1) assert copyright on the software, and (2) offer you this License +giving you legal permission to copy, distribute and/or modify it. + + For the developers' and authors' protection, the GPL clearly explains +that there is no warranty for this free software. For both users' and +authors' sake, the GPL requires that modified versions be marked as +changed, so that their problems will not be attributed erroneously to +authors of previous versions. + + Some devices are designed to deny users access to install or run +modified versions of the software inside them, although the manufacturer +can do so. This is fundamentally incompatible with the aim of +protecting users' freedom to change the software. The systematic +pattern of such abuse occurs in the area of products for individuals to +use, which is precisely where it is most unacceptable. Therefore, we +have designed this version of the GPL to prohibit the practice for those +products. If such problems arise substantially in other domains, we +stand ready to extend this provision to those domains in future versions +of the GPL, as needed to protect the freedom of users. + + Finally, every program is threatened constantly by software patents. +States should not allow patents to restrict development and use of +software on general-purpose computers, but in those that do, we wish to +avoid the special danger that patents applied to a free program could +make it effectively proprietary. To prevent this, the GPL assures that +patents cannot be used to render the program non-free. + + The precise terms and conditions for copying, distribution and +modification follow. + + TERMS AND CONDITIONS + + 0. Definitions. + + "This License" refers to version 3 of the GNU General Public License. + + "Copyright" also means copyright-like laws that apply to other kinds of +works, such as semiconductor masks. + + "The Program" refers to any copyrightable work licensed under this +License. Each licensee is addressed as "you". "Licensees" and +"recipients" may be individuals or organizations. + + To "modify" a work means to copy from or adapt all or part of the work +in a fashion requiring copyright permission, other than the making of an +exact copy. The resulting work is called a "modified version" of the +earlier work or a work "based on" the earlier work. + + A "covered work" means either the unmodified Program or a work based +on the Program. + + To "propagate" a work means to do anything with it that, without +permission, would make you directly or secondarily liable for +infringement under applicable copyright law, except executing it on a +computer or modifying a private copy. Propagation includes copying, +distribution (with or without modification), making available to the +public, and in some countries other activities as well. + + To "convey" a work means any kind of propagation that enables other +parties to make or receive copies. Mere interaction with a user through +a computer network, with no transfer of a copy, is not conveying. + + An interactive user interface displays "Appropriate Legal Notices" +to the extent that it includes a convenient and prominently visible +feature that (1) displays an appropriate copyright notice, and (2) +tells the user that there is no warranty for the work (except to the +extent that warranties are provided), that licensees may convey the +work under this License, and how to view a copy of this License. If +the interface presents a list of user commands or options, such as a +menu, a prominent item in the list meets this criterion. + + 1. Source Code. + + The "source code" for a work means the preferred form of the work +for making modifications to it. "Object code" means any non-source +form of a work. + + A "Standard Interface" means an interface that either is an official +standard defined by a recognized standards body, or, in the case of +interfaces specified for a particular programming language, one that +is widely used among developers working in that language. + + The "System Libraries" of an executable work include anything, other +than the work as a whole, that (a) is included in the normal form of +packaging a Major Component, but which is not part of that Major +Component, and (b) serves only to enable use of the work with that +Major Component, or to implement a Standard Interface for which an +implementation is available to the public in source code form. A +"Major Component", in this context, means a major essential component +(kernel, window system, and so on) of the specific operating system +(if any) on which the executable work runs, or a compiler used to +produce the work, or an object code interpreter used to run it. + + The "Corresponding Source" for a work in object code form means all +the source code needed to generate, install, and (for an executable +work) run the object code and to modify the work, including scripts to +control those activities. However, it does not include the work's +System Libraries, or general-purpose tools or generally available free +programs which are used unmodified in performing those activities but +which are not part of the work. For example, Corresponding Source +includes interface definition files associated with source files for +the work, and the source code for shared libraries and dynamically +linked subprograms that the work is specifically designed to require, +such as by intimate data communication or control flow between those +subprograms and other parts of the work. + + The Corresponding Source need not include anything that users +can regenerate automatically from other parts of the Corresponding +Source. + + The Corresponding Source for a work in source code form is that +same work. + + 2. Basic Permissions. + + All rights granted under this License are granted for the term of +copyright on the Program, and are irrevocable provided the stated +conditions are met. This License explicitly affirms your unlimited +permission to run the unmodified Program. The output from running a +covered work is covered by this License only if the output, given its +content, constitutes a covered work. This License acknowledges your +rights of fair use or other equivalent, as provided by copyright law. + + You may make, run and propagate covered works that you do not +convey, without conditions so long as your license otherwise remains +in force. You may convey covered works to others for the sole purpose +of having them make modifications exclusively for you, or provide you +with facilities for running those works, provided that you comply with +the terms of this License in conveying all material for which you do +not control copyright. Those thus making or running the covered works +for you must do so exclusively on your behalf, under your direction +and control, on terms that prohibit them from making any copies of +your copyrighted material outside their relationship with you. + + Conveying under any other circumstances is permitted solely under +the conditions stated below. Sublicensing is not allowed; section 10 +makes it unnecessary. + + 3. Protecting Users' Legal Rights From Anti-Circumvention Law. + + No covered work shall be deemed part of an effective technological +measure under any applicable law fulfilling obligations under article +11 of the WIPO copyright treaty adopted on 20 December 1996, or +similar laws prohibiting or restricting circumvention of such +measures. + + When you convey a covered work, you waive any legal power to forbid +circumvention of technological measures to the extent such circumvention +is effected by exercising rights under this License with respect to +the covered work, and you disclaim any intention to limit operation or +modification of the work as a means of enforcing, against the work's +users, your or third parties' legal rights to forbid circumvention of +technological measures. + + 4. Conveying Verbatim Copies. + + You may convey verbatim copies of the Program's source code as you +receive it, in any medium, provided that you conspicuously and +appropriately publish on each copy an appropriate copyright notice; +keep intact all notices stating that this License and any +non-permissive terms added in accord with section 7 apply to the code; +keep intact all notices of the absence of any warranty; and give all +recipients a copy of this License along with the Program. + + You may charge any price or no price for each copy that you convey, +and you may offer support or warranty protection for a fee. + + 5. Conveying Modified Source Versions. + + You may convey a work based on the Program, or the modifications to +produce it from the Program, in the form of source code under the +terms of section 4, provided that you also meet all of these conditions: + + a) The work must carry prominent notices stating that you modified + it, and giving a relevant date. + + b) The work must carry prominent notices stating that it is + released under this License and any conditions added under section + 7. This requirement modifies the requirement in section 4 to + "keep intact all notices". + + c) You must license the entire work, as a whole, under this + License to anyone who comes into possession of a copy. This + License will therefore apply, along with any applicable section 7 + additional terms, to the whole of the work, and all its parts, + regardless of how they are packaged. This License gives no + permission to license the work in any other way, but it does not + invalidate such permission if you have separately received it. + + d) If the work has interactive user interfaces, each must display + Appropriate Legal Notices; however, if the Program has interactive + interfaces that do not display Appropriate Legal Notices, your + work need not make them do so. + + A compilation of a covered work with other separate and independent +works, which are not by their nature extensions of the covered work, +and which are not combined with it such as to form a larger program, +in or on a volume of a storage or distribution medium, is called an +"aggregate" if the compilation and its resulting copyright are not +used to limit the access or legal rights of the compilation's users +beyond what the individual works permit. Inclusion of a covered work +in an aggregate does not cause this License to apply to the other +parts of the aggregate. + + 6. Conveying Non-Source Forms. + + You may convey a covered work in object code form under the terms +of sections 4 and 5, provided that you also convey the +machine-readable Corresponding Source under the terms of this License, +in one of these ways: + + a) Convey the object code in, or embodied in, a physical product + (including a physical distribution medium), accompanied by the + Corresponding Source fixed on a durable physical medium + customarily used for software interchange. + + b) Convey the object code in, or embodied in, a physical product + (including a physical distribution medium), accompanied by a + written offer, valid for at least three years and valid for as + long as you offer spare parts or customer support for that product + model, to give anyone who possesses the object code either (1) a + copy of the Corresponding Source for all the software in the + product that is covered by this License, on a durable physical + medium customarily used for software interchange, for a price no + more than your reasonable cost of physically performing this + conveying of source, or (2) access to copy the + Corresponding Source from a network server at no charge. + + c) Convey individual copies of the object code with a copy of the + written offer to provide the Corresponding Source. This + alternative is allowed only occasionally and noncommercially, and + only if you received the object code with such an offer, in accord + with subsection 6b. + + d) Convey the object code by offering access from a designated + place (gratis or for a charge), and offer equivalent access to the + Corresponding Source in the same way through the same place at no + further charge. You need not require recipients to copy the + Corresponding Source along with the object code. If the place to + copy the object code is a network server, the Corresponding Source + may be on a different server (operated by you or a third party) + that supports equivalent copying facilities, provided you maintain + clear directions next to the object code saying where to find the + Corresponding Source. Regardless of what server hosts the + Corresponding Source, you remain obligated to ensure that it is + available for as long as needed to satisfy these requirements. + + e) Convey the object code using peer-to-peer transmission, provided + you inform other peers where the object code and Corresponding + Source of the work are being offered to the general public at no + charge under subsection 6d. + + A separable portion of the object code, whose source code is excluded +from the Corresponding Source as a System Library, need not be +included in conveying the object code work. + + A "User Product" is either (1) a "consumer product", which means any +tangible personal property which is normally used for personal, family, +or household purposes, or (2) anything designed or sold for incorporation +into a dwelling. In determining whether a product is a consumer product, +doubtful cases shall be resolved in favor of coverage. For a particular +product received by a particular user, "normally used" refers to a +typical or common use of that class of product, regardless of the status +of the particular user or of the way in which the particular user +actually uses, or expects or is expected to use, the product. A product +is a consumer product regardless of whether the product has substantial +commercial, industrial or non-consumer uses, unless such uses represent +the only significant mode of use of the product. + + "Installation Information" for a User Product means any methods, +procedures, authorization keys, or other information required to install +and execute modified versions of a covered work in that User Product from +a modified version of its Corresponding Source. The information must +suffice to ensure that the continued functioning of the modified object +code is in no case prevented or interfered with solely because +modification has been made. + + If you convey an object code work under this section in, or with, or +specifically for use in, a User Product, and the conveying occurs as +part of a transaction in which the right of possession and use of the +User Product is transferred to the recipient in perpetuity or for a +fixed term (regardless of how the transaction is characterized), the +Corresponding Source conveyed under this section must be accompanied +by the Installation Information. But this requirement does not apply +if neither you nor any third party retains the ability to install +modified object code on the User Product (for example, the work has +been installed in ROM). + + The requirement to provide Installation Information does not include a +requirement to continue to provide support service, warranty, or updates +for a work that has been modified or installed by the recipient, or for +the User Product in which it has been modified or installed. Access to a +network may be denied when the modification itself materially and +adversely affects the operation of the network or violates the rules and +protocols for communication across the network. + + Corresponding Source conveyed, and Installation Information provided, +in accord with this section must be in a format that is publicly +documented (and with an implementation available to the public in +source code form), and must require no special password or key for +unpacking, reading or copying. + + 7. Additional Terms. + + "Additional permissions" are terms that supplement the terms of this +License by making exceptions from one or more of its conditions. +Additional permissions that are applicable to the entire Program shall +be treated as though they were included in this License, to the extent +that they are valid under applicable law. If additional permissions +apply only to part of the Program, that part may be used separately +under those permissions, but the entire Program remains governed by +this License without regard to the additional permissions. + + When you convey a copy of a covered work, you may at your option +remove any additional permissions from that copy, or from any part of +it. (Additional permissions may be written to require their own +removal in certain cases when you modify the work.) You may place +additional permissions on material, added by you to a covered work, +for which you have or can give appropriate copyright permission. + + Notwithstanding any other provision of this License, for material you +add to a covered work, you may (if authorized by the copyright holders of +that material) supplement the terms of this License with terms: + + a) Disclaiming warranty or limiting liability differently from the + terms of sections 15 and 16 of this License; or + + b) Requiring preservation of specified reasonable legal notices or + author attributions in that material or in the Appropriate Legal + Notices displayed by works containing it; or + + c) Prohibiting misrepresentation of the origin of that material, or + requiring that modified versions of such material be marked in + reasonable ways as different from the original version; or + + d) Limiting the use for publicity purposes of names of licensors or + authors of the material; or + + e) Declining to grant rights under trademark law for use of some + trade names, trademarks, or service marks; or + + f) Requiring indemnification of licensors and authors of that + material by anyone who conveys the material (or modified versions of + it) with contractual assumptions of liability to the recipient, for + any liability that these contractual assumptions directly impose on + those licensors and authors. + + All other non-permissive additional terms are considered "further +restrictions" within the meaning of section 10. If the Program as you +received it, or any part of it, contains a notice stating that it is +governed by this License along with a term that is a further +restriction, you may remove that term. If a license document contains +a further restriction but permits relicensing or conveying under this +License, you may add to a covered work material governed by the terms +of that license document, provided that the further restriction does +not survive such relicensing or conveying. + + If you add terms to a covered work in accord with this section, you +must place, in the relevant source files, a statement of the +additional terms that apply to those files, or a notice indicating +where to find the applicable terms. + + Additional terms, permissive or non-permissive, may be stated in the +form of a separately written license, or stated as exceptions; +the above requirements apply either way. + + 8. Termination. + + You may not propagate or modify a covered work except as expressly +provided under this License. Any attempt otherwise to propagate or +modify it is void, and will automatically terminate your rights under +this License (including any patent licenses granted under the third +paragraph of section 11). + + However, if you cease all violation of this License, then your +license from a particular copyright holder is reinstated (a) +provisionally, unless and until the copyright holder explicitly and +finally terminates your license, and (b) permanently, if the copyright +holder fails to notify you of the violation by some reasonable means +prior to 60 days after the cessation. + + Moreover, your license from a particular copyright holder is +reinstated permanently if the copyright holder notifies you of the +violation by some reasonable means, this is the first time you have +received notice of violation of this License (for any work) from that +copyright holder, and you cure the violation prior to 30 days after +your receipt of the notice. + + Termination of your rights under this section does not terminate the +licenses of parties who have received copies or rights from you under +this License. If your rights have been terminated and not permanently +reinstated, you do not qualify to receive new licenses for the same +material under section 10. + + 9. Acceptance Not Required for Having Copies. + + You are not required to accept this License in order to receive or +run a copy of the Program. Ancillary propagation of a covered work +occurring solely as a consequence of using peer-to-peer transmission +to receive a copy likewise does not require acceptance. However, +nothing other than this License grants you permission to propagate or +modify any covered work. These actions infringe copyright if you do +not accept this License. Therefore, by modifying or propagating a +covered work, you indicate your acceptance of this License to do so. + + 10. Automatic Licensing of Downstream Recipients. + + Each time you convey a covered work, the recipient automatically +receives a license from the original licensors, to run, modify and +propagate that work, subject to this License. You are not responsible +for enforcing compliance by third parties with this License. + + An "entity transaction" is a transaction transferring control of an +organization, or substantially all assets of one, or subdividing an +organization, or merging organizations. If propagation of a covered +work results from an entity transaction, each party to that +transaction who receives a copy of the work also receives whatever +licenses to the work the party's predecessor in interest had or could +give under the previous paragraph, plus a right to possession of the +Corresponding Source of the work from the predecessor in interest, if +the predecessor has it or can get it with reasonable efforts. + + You may not impose any further restrictions on the exercise of the +rights granted or affirmed under this License. For example, you may +not impose a license fee, royalty, or other charge for exercise of +rights granted under this License, and you may not initiate litigation +(including a cross-claim or counterclaim in a lawsuit) alleging that +any patent claim is infringed by making, using, selling, offering for +sale, or importing the Program or any portion of it. + + 11. Patents. + + A "contributor" is a copyright holder who authorizes use under this +License of the Program or a work on which the Program is based. The +work thus licensed is called the contributor's "contributor version". + + A contributor's "essential patent claims" are all patent claims +owned or controlled by the contributor, whether already acquired or +hereafter acquired, that would be infringed by some manner, permitted +by this License, of making, using, or selling its contributor version, +but do not include claims that would be infringed only as a +consequence of further modification of the contributor version. For +purposes of this definition, "control" includes the right to grant +patent sublicenses in a manner consistent with the requirements of +this License. + + Each contributor grants you a non-exclusive, worldwide, royalty-free +patent license under the contributor's essential patent claims, to +make, use, sell, offer for sale, import and otherwise run, modify and +propagate the contents of its contributor version. + + In the following three paragraphs, a "patent license" is any express +agreement or commitment, however denominated, not to enforce a patent +(such as an express permission to practice a patent or covenant not to +sue for patent infringement). To "grant" such a patent license to a +party means to make such an agreement or commitment not to enforce a +patent against the party. + + If you convey a covered work, knowingly relying on a patent license, +and the Corresponding Source of the work is not available for anyone +to copy, free of charge and under the terms of this License, through a +publicly available network server or other readily accessible means, +then you must either (1) cause the Corresponding Source to be so +available, or (2) arrange to deprive yourself of the benefit of the +patent license for this particular work, or (3) arrange, in a manner +consistent with the requirements of this License, to extend the patent +license to downstream recipients. "Knowingly relying" means you have +actual knowledge that, but for the patent license, your conveying the +covered work in a country, or your recipient's use of the covered work +in a country, would infringe one or more identifiable patents in that +country that you have reason to believe are valid. + + If, pursuant to or in connection with a single transaction or +arrangement, you convey, or propagate by procuring conveyance of, a +covered work, and grant a patent license to some of the parties +receiving the covered work authorizing them to use, propagate, modify +or convey a specific copy of the covered work, then the patent license +you grant is automatically extended to all recipients of the covered +work and works based on it. + + A patent license is "discriminatory" if it does not include within +the scope of its coverage, prohibits the exercise of, or is +conditioned on the non-exercise of one or more of the rights that are +specifically granted under this License. You may not convey a covered +work if you are a party to an arrangement with a third party that is +in the business of distributing software, under which you make payment +to the third party based on the extent of your activity of conveying +the work, and under which the third party grants, to any of the +parties who would receive the covered work from you, a discriminatory +patent license (a) in connection with copies of the covered work +conveyed by you (or copies made from those copies), or (b) primarily +for and in connection with specific products or compilations that +contain the covered work, unless you entered into that arrangement, +or that patent license was granted, prior to 28 March 2007. + + Nothing in this License shall be construed as excluding or limiting +any implied license or other defenses to infringement that may +otherwise be available to you under applicable patent law. + + 12. No Surrender of Others' Freedom. + + If conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot convey a +covered work so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you may +not convey it at all. For example, if you agree to terms that obligate you +to collect a royalty for further conveying from those to whom you convey +the Program, the only way you could satisfy both those terms and this +License would be to refrain entirely from conveying the Program. + + 13. Use with the GNU Affero General Public License. + + Notwithstanding any other provision of this License, you have +permission to link or combine any covered work with a work licensed +under version 3 of the GNU Affero General Public License into a single +combined work, and to convey the resulting work. The terms of this +License will continue to apply to the part which is the covered work, +but the special requirements of the GNU Affero General Public License, +section 13, concerning interaction through a network will apply to the +combination as such. + + 14. Revised Versions of this License. + + The Free Software Foundation may publish revised and/or new versions of +the GNU General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + + Each version is given a distinguishing version number. If the +Program specifies that a certain numbered version of the GNU General +Public License "or any later version" applies to it, you have the +option of following the terms and conditions either of that numbered +version or of any later version published by the Free Software +Foundation. If the Program does not specify a version number of the +GNU General Public License, you may choose any version ever published +by the Free Software Foundation. + + If the Program specifies that a proxy can decide which future +versions of the GNU General Public License can be used, that proxy's +public statement of acceptance of a version permanently authorizes you +to choose that version for the Program. + + Later license versions may give you additional or different +permissions. However, no additional obligations are imposed on any +author or copyright holder as a result of your choosing to follow a +later version. + + 15. Disclaimer of Warranty. + + THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY +APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT +HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY +OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, +THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR +PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM +IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF +ALL NECESSARY SERVICING, REPAIR OR CORRECTION. + + 16. Limitation of Liability. + + IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS +THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY +GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE +USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF +DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD +PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), +EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF +SUCH DAMAGES. + + 17. Interpretation of Sections 15 and 16. + + If the disclaimer of warranty and limitation of liability provided +above cannot be given local legal effect according to their terms, +reviewing courts shall apply local law that most closely approximates +an absolute waiver of all civil liability in connection with the +Program, unless a warranty or assumption of liability accompanies a +copy of the Program in return for a fee. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +state the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + + Copyright (C) + + This program is free software: you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation, either version 3 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the + GNU General Public License for more details. + + You should have received a copy of the GNU General Public License + along with this program. If not, see . + +Also add information on how to contact you by electronic and paper mail. + + If the program does terminal interaction, make it output a short +notice like this when it starts in an interactive mode: + + Copyright (C) + This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. + This is free software, and you are welcome to redistribute it + under certain conditions; type `show c' for details. + +The hypothetical commands `show w' and `show c' should show the appropriate +parts of the General Public License. Of course, your program's commands +might be different; for a GUI interface, you would use an "about box". + + You should also get your employer (if you work as a programmer) or school, +if any, to sign a "copyright disclaimer" for the program, if necessary. +For more information on this, and how to apply and follow the GNU GPL, see +. + + The GNU General Public License does not permit incorporating your program +into proprietary programs. If your program is a subroutine library, you +may consider it more useful to permit linking proprietary applications with +the library. If this is what you want to do, use the GNU Lesser General +Public License instead of this License.

On switching away from the -virtual terminal (VT) hosting Weston, all input devices are closed and -the DRM master capability is dropped, so that other servers, -including -.BR Xorg (1), -can run on other VTs. On switching back to Weston's VT, input devices -and DRM master are re-acquired through the parent process -.BR weston-launch . - -The DRM backend also supports virtual outputs that are transmitted over -an RTP session as a series of JPEG images (RTP payload type 26) to a remote -client. Virtual outputs are configured in the -.BR remote-output -section of -.BR weston.ini. -. -.\" *************************************************************** -.SH CONFIGURATION -. -The DRM backend uses the following entries from -.BR weston.ini . -.SS Section output -.TP -\fBname\fR=\fIconnector\fR -The KMS connector name identifying the output, for instance -.IR LVDS1 . -.TP -\fBmode\fR=\fImode\fR -Specify the video mode for the output. The argument -.I mode -can be one of the words -.BR off " to turn the output off, " -.BR preferred " to use the monitor's preferred video mode, or " -.BR current " to use the current video mode and avoid a mode switch." -It can also be a resolution as: -.TP -\fBmode\fR=\fIwidth\fBx\fIheight\fR -.TP -\fBmode\fR=\fIwidth\fBx\fIheight\fB@\fIrefresh_rate\fR -Specify a mode with a given refresh-rate measured in Hz. -.TP -\fBmode\fR=\fIwidth\fBx\fIheight\fB@\fIrefresh_rate ratio\fR -Here \fIratio\fR is Picture Aspect-Ratio which can have values as 4:3, 16:9, -64:27, and 256:135. This resolution-format helps to select a CEA mode, if such a -video mode is present in the mode-list of the output. - -CEA defines the timing of a video mode, which is considered as a standard for -HDMI spcification and compliance testing. It defines each and every parameter of -a video mode, like hactive, vactive, vfront, vback etc., including aspect-ratio -information. For CEA modes, the drm layer, stores this aspect-ratio information -in user-mode (drmModeModeInfo) flag bits 19-22. For the non-CEA modes a value of -0 is stored in the aspect-ratio flag bits. - -Each CEA-mode is identified by a unique, Video Identification Code (VIC). -For example, VIC=4 is 1280x720@60 aspect-ratio 16:9. This mode will be -different than a non-CEA mode 1280x720@60 0:0. When the video mode -1280x720@60 0:0 is applied, since its timing doesn't exactly match with the CEA -information for VIC=4, it would be treated as a non-CEA mode. Also, while setting -the HDMI-AVI-Inforframe, VIC parameter will be given as '0'. If video mode -1280x720@60 16:9 is applied, its CEA timimgs matches with that of video mode with -VIC=4, so the VIC parameter in HDMI-AVI-Infoframe will be set to 4. - -Many a times, an output may have both CEA and non-CEA modes, which are similar -in all resepct, differing only in the aspect-ratio. A user can select a CEA mode -by giving the aspect-ratio, along with the other arguments for the mode. -By omitting the aspect-ratio, user can specify the non-CEA modes. -This helps when certification testing is done, in tests like 7-27, the -HDMI-analyzer applies a particular CEA mode, and expects the applied mode to be -with exactly same timings, including the aspect-ratio and VIC field. - -The resolution can also be a detailed mode line as below. -.TP -\fBmode\fR=\fIdotclock hdisp hsyncstart hsyncend htotal \ -vdisp vsyncstart vsyncend vtotal hflag vflag\fR -Use the given detailed mode line as the video mode for this output. -The definition is the same as in -.BR xorg.conf "(5), and " cvt (1) -can generate detailed mode lines. -.TP -\fBtransform\fR=\fItransform\fR -Transform for the output, which can be rotated in 90-degree steps -and possibly flipped.

A Wayland server is a -display server, a window manager, and a compositor all in one. Weston has -several backends as loadable modules: it can run on Linux KMS (kernel -modesetting via DRM), as an X client, or inside another Wayland server -instance. - -Weston supports fundamentally different graphical user interface paradigms via -shell plugins. Two plugins are provided: the desktop shell, and the tablet -shell. - -When weston is started as the first windowing system (i.e. not under X nor -under another Wayland server), it should be done with the command -.B weston-launch -to set up proper privileged access to devices. If your system supports -the logind D-Bus API and the support has been built into weston as well, -it is possible to start weston with just -.BR weston . - -Weston also supports X clients via -.BR XWayland ", see below." -. -.\" *************************************************************** -.SH BACKENDS -.TP -.I drm-backend.so -The DRM backend uses Linux KMS for output and evdev devices for input. -It supports multiple monitors in a unified desktop with DPMS. See -.BR weston-drm (7), -if installed. -.TP -.I wayland-backend.so -The Wayland backend runs on another Wayland server, a different Weston -instance, for example. Weston shows up as a single desktop window on -the parent server. -.TP -.I x11-backend.so -The X11 backend runs on an X server. Each Weston output becomes an -X window. This is a cheap way to test multi-monitor support of a -Wayland shell, desktop, or applications. -.TP -.I rdp-backend.so -The RDP backend runs in memory without the need of graphical hardware. Access -to the desktop is done by using the RDP protocol. Each connecting -client has its own seat making it a cheap way to test multi-seat support. See -.BR weston-rdp (7), -if installed. -. -.\" *************************************************************** -.SH SHELLS -Each of these shells have its own public protocol interface for clients. -This means that a client must be specifically written for a shell protocol, -otherwise it will not work. -.TP -Desktop shell -Desktop shell is like a modern X desktop environment, concentrating -on traditional keyboard and mouse user interfaces and the familiar -desktop-like window management. Desktop shell consists of the -shell plugin -.I desktop-shell.so -and the special client -.B weston-desktop-shell -which provides the wallpaper, panel, and screen locking dialog. -.TP -Fullscreen shell -Fullscreen shell is intended for a client that needs to take over -whole outputs, often all outputs. This is primarily intended for -running another compositor on Weston. The other compositor does not -need to handle any platform-specifics like DRM/KMS or evdev/libinput. -The shell consists only of the shell plugin -.IR fullscreen-shell.so . -.TP -IVI-shell -In-vehicle infotainment shell is a special purpose shell that exposes -a GENIVI Layer Manager compatible API to controller modules, and a very -simple shell protocol towards clients. IVI-shell starts with loading -.IR ivi-shell.so , -and then a controller module which may launch helper clients. -. -.\" *************************************************************** -.SH XWAYLAND -XWayland requires a special X.org server to be installed. This X server will -connect to a Wayland server as a Wayland client, and X clients will connect to -the X server. XWayland provides backwards compatibility to X applications in a -Wayland stack. - -XWayland is activated by instructing -.BR weston " to load the XWayland module, see " EXAMPLES . -Weston starts listening on a new X display socket, and exports it in the -environment variable -.BR DISPLAY . -When the first X client connects, Weston launches a special X server as a -Wayland client to handle the X client and all future X clients. - -It has also its own X window manager where cursor themes and sizes can be -chosen using -.BR XCURSOR_PATH -and -.BR XCURSOR_SIZE " environment variables. See " ENVIRONMENT . -. -.\" *************************************************************** -.SH OPTIONS -. -.SS Weston core options: -.TP -\fB\-\^B\fR\fIbackend.so\fR, \fB\-\-backend\fR=\fIbackend.so\fR -Load -.I backend.so -instead of the default backend. The file is searched for in -.IR "@weston_modules_dir@" , -or you can pass an absolute path.

First, a client may cause a denial-of-service -blocking the compositor by providing an unsuitable file descriptor, and -second, the debug messages may expose sensitive information. -Additionally this will expose weston-screenshooter interface allowing the user -to take screenshots of the outputs using weston-screenshooter application, -which can lead to silently leaking the output contents. This option should -not be used in production. -.TP -\fB\-\^l\fIscope1,scope2\fR, \fB\-\-logger-scopes\fR=\fIscope1,scope2\fR -Specify to which log scopes should subscribe to.

Useful to control which streams to -write data into the flight recorder. Flight recorder has limited space, once -the flight recorder is full new data will overwrite the old data. Without any -scopes specified, it subscribes to 'log' and 'drm-backend' scopes. -.TP -.BR \-\-version -Print the program version. -.TP -.BR \-\^h ", " \-\-help -Print a summary of command line options, and quit. -.TP -\fB\-\^i\fR\fIN\fR, \fB\-\-idle\-time\fR=\fIN\fR -Set the idle timeout to -.I N -seconds. The default timeout is 300 seconds. When there has not been any -user input for the idle timeout, Weston enters an inactive mode. The -screen fades to black, monitors may switch off, and the shell may lock -the session. -A value of 0 effectively disables the timeout. -.TP -\fB\-\-log\fR=\fIfile.log\fR -Append log messages to the file -.I file.log -instead of writing them to stderr. -.TP -\fB\-\-xwayland\fR -Ask Weston to load the XWayland module. -.TP -\fB\-\-modules\fR=\fImodule1.so,module2.so\fR -Load the comma-separated list of modules.
