Requires Lilu 1.5.6 or newer. #### Features - Fixes boot to black screen on AMD and NVIDIA - Fixes sleep wake to black screen on AMD - Fixes boot screen distortion in certain cases - Fixes transmitter/encoder in autodetected connectors for multimonitor support (`-raddvi`) - Fixes HD 7730/7750/7770/R7 250/R7 250X initialisation (`radpg=15`) - Allows tuning of aty_config, aty_properties, cail_properties via ACPI - Allows enforcing 24-bit mode on unsupported displays (`-rad24`) - Allows booting without video acceleration (`-radvesa`) - Allows automatically setting GPU model name or providing it manually for RadeonFramebuffer - Allows specifying custom connectors via device properties for RadeonFramebuffer - Allows tuning autodetected connector priority via device properties (HD 7xxx or newer) - Fixes an issue in AppleGraphicsDevicePolicy.kext so that we could use a MacPro6,1 board-id/model combination, without the usual hang with a black screen. [Patching AppleGraphicsDevicePolicy.kext](https://pikeralpha.wordpress.com/2015/11/23/patching-applegraphicsdevicepolicy-kext) - Modifies macOS to recognize NVIDIA's web drivers as platform binaries. This resolves the issue with transparent windows without content, which appear for applications that use Metal and have Library Validation enabled. Common affected applications are iBooks and Little Snitch Network Monitor, though this patch is universal and fixes them all. [NVWebDriverLibValFix](https://github.com/mologie/NVWebDriverLibValFix) - Injects IOVARendererID into GPU properties (required for Shiki-based solution for non-freezing Intel and/or any discrete GPU) - For Intel HD digital audio HDMI, DP, Digital DVI (Patches connector-type DP -> HDMI) - Fixes NVIDIA GPU interface stuttering on 10.13 (official and web drivers) - Fixes the kernel panic caused by an invalid link rate reported by DPCD on some laptops with Intel IGPU. - Fixes the infinite loop on establishing Intel HDMI connections with a higher pixel clock rate on Skylake, Kaby Lake and Coffee Lake platforms. - Implements the driver support for onboard LSPCON chips to enable DisplayPort to HDMI 2.0 output on some platforms with Intel IGPU. - Enforces complete modeset on non-built-in displays on Kaby Lake and newer to fix booting to black screen. - Allows non-supported cards to use HW video encoder (`-radcodec`) - Fixes choppy video playback on Intel Kaby Lake and newer. - Fixes black screen on Intel HD since 10.15.5. - Adds workaround for rare force wake timeout panics on Intel KBL and CFL. - Supports all valid Core Display Clock (CDCLK) freqencies on Intel ICL platforms. - Fixes the kernel panic caused by an incorrectly calculated amount of DVMT pre-allocated memory on Intel ICL platforms. - Makes brightness transitions smoother on Intel IVB+ platforms. #### Documentation Read [FAQs](https://github.com/acidanthera/WhateverGreen/blob/master/Manual/) and avoid asking any questions.
