# Introduction
Seeking for a tools to swicht entirely from default **Intel®** GPU to the discret **Nvidia®** graphic card, I discover **[FedoraPrime](https://github.com/bosim/FedoraPrime)**.

It comes really useful for my default distro, **Fedora**, but not so cool for my custom **Nvidia®** driver install, **[FedoraPrime](https://github.com/bosim/FedoraPrime)** is **Fedora** only with a default driver config.

Thus, I discided to go deeper to solve that particular issue and a few others as well.
 - Choose for a custom driver install
 - Automatically configure xrandr for multi screens (or not)
 - Start **Nvidia®** GPU instead the default one whatever the end user desktop you choose.

# Update message
### 2019-09-05 - v0.9.20
**WARNING**: Do a 'sudo make install' this time, too much important things changed and don't forget to make a backup of /etc/nvidia-prime.
(with root/admin terminal, do:)
```mv -f /etc/nvidia-prime /etc/nvidia-prime.bak``` (to remove safely after controls)

### 2019-08-20
There were many issues with grub config reported. It is hopefully fix and updated now. Please don't forget to report even if you think it's too minor and pointless.

### 2018-04-01
Dev test was running on Fedora 24, since upgraded to Fedora 27 it appears that xrandr on modesettings is broken and dosn't work anymore for discret nvidia.

### 2018-04-13
Finally, the script needed a complete rewrite. For user, basics are still the same, but they work differently than the previous version.

Read Changelog display before install/uninstall/update.

Thanks to the **[Nvidia Devtalk](https://devtalk.nvidia.com/default/topic/1024318/linux/-solved-nvidia-prime-on-dual-gpu-configuration-giving-a-blank-screen/2)** thread and to **nospam_** that giving me the necessary base to understand what changed. 

Also added a libraries and xorg config editor.

Library.conf is install by default and checked if configured.

There stil some issue with some session managers, see **Known Issues** at page bottom.

Hope you'll like those changes and don't forget to send any bug you get. :)

### 2018-04-16
Big mistake in repos upload :s. Forgot to send library.conf with last upgrade. My apologies.

### 2018-04-22
Multi display issue, see **CHANGELOG.md**.

### 2018-04-24
Added options config file, report.sample and some fixes to grub and xrandr sections. See **CHANGELOG.md**.

# Usage

## Default usage :
  ```sh
  nvidia-prime-select option
  ```

## Options
 - *intel* : use the default GPU
 - *nvidia* : use the **Nvidia®** GPU
 
## Before all
In old version it was mandatory to edit library.conf first in case of special Nvidia drivers install. Now you can setup them directly with nvidia-prime-ui before entering you new setup. 

Gnome and Cinnamon use a *monitors.xml*(~/.config/monitors.xml) file to keep your screen config and overide any other setup if it doesn't match the xml file.

Gdm Gnome3 may cause issue in some case. See **Issue** chapter in bottom ofthe page and send report if you can fix it this way.

**nvidia-prime-select** comes with a *library.conf* file to set custom installation directories up (same case if you come from an other distro). If you're in this case, edit it first before launching/installing anything.

Example of my custom driver install in Fedora 23:
```sh
  nv_drv_32='/opt/nvidia/lib'
  nv_drv_64='/opt/nvidia/lib64'
  nv_xorg_path='/opt/nvidia/xorg/modules'
  rc_dir='/etc/rc.d'
```

Or use the simpliest way and launch **nvidia-prime-ui** from settings menu.

**nvidia-prime-select** come also with 2 default xorg configs for **Intel®** and **Nvidia®**. Edit them as you wish before or after luanching command (edit function is available in nvidia-prime-ui).

## Install
**nvidia-prime-select** use the same install process as **[FedoraPrime](https://github.com/bosim/FedoraPrime)** :
  ```sh
  git clone https://github.com/wildtruc/nvidia-prime-select.git
  cd nvidia-prime-select
  sudo make install
  ```

To update, run :
  ```sh
  sudo make update
  ```
To uninstall, run :
  ```sh
  sudo make uninstall
  ```

When done, launch the commandline as admin/superuser or with nvidia-prime-ui as normal user. Then logout and restart your session.

The script will setup your actual *xrandr* configuration automatically.

## Dependencies
 - zenity (updates messages and UI display)

## Notes
*Option "DPI" "96 x 96"* is set by default in the *xorg.nvidia.conf* because *xrandr* set it at *75* by default. If you have a weaker **Nvidia®** GPU, it's maybe a good thing to let it at *75* if you want to play some games smoother.

Usually when the Nvidia® GPU starts the screen display some weird black lines at first, if it is, it means that Nvidia® GPU is started.

## Known issues
The script has been test on Gnome Shell, Gnome Classic, Cinnamon, LXQT, Kodi (for previous version, lightdm only for new one).

 - The only issue comes with Gnome Classic, desktop crash on final start. I'm not sure it comes from Gnome Classic itself.
 - For **Fedora** users upgrading from **Fedora 23** to **24** using the **dnf** tools, don't forget to re-enable the service after the first reboot. You have to probably reset your display *xrandr* config too.
 - Since **Fedora 24**, *rc.nivia* schedule time set is not enough to let *GDM* fully start. Need to extend from 5 to 10 secondes (update 10/08/16).
 - Session restart on gdm (gnome3) may cause result in a blank screen. In previous nvidia-prime-select, this issues was fix by inserting a delay waiting for full gdm start before insert xrandr command line. Try to uncomment 'sleep' function in /etc/nvidia-prime/xinitrc.prime and different delay. If it doesn't fix, think to change session manager to lightdm.
 - In some case, xrandr display config (~.config/monitors.xml) could conflict with nvidia-prime-select xrandr auto conf function. First, remove ~.config/monitors.xml, and restart your session. If it doesn't fix, set your display again and disable nvidia-prime.desktop autostart (menu > system > pref > personal > autostart), then restart your session.
 - At session restart login has a strange behaviour and could take 30/40s to display correctly. It maybe a polkit issue, but not sure. Need debug and figure out.
 - Do not hesitate to send issue reports on Github page.
