-====== Xorg Drivers ======
-===== openSUSE =====
-  sudo zypper search 'xf86-video'
-  xf86-video-amdgpu
-  xf86-video-ati
-  xf86-video-intel
-===== Fedora =====
-  sudo dnf search 'xorg-x11-drv'
-  xorg-x11-drv-amdgpu
-====== Monitor/Display ======
-===== 4K@60Hz RB =====
-  * 4k@60Hz CVT-RB
-  * Fixes unstable HDMI at 4K@60Hz, and overly-bright colors on DisplayPort
-  * :!: The ''grep'' here confirms the expected Modeline ((if grep reports nothing, use whatever is reported instead))
-  * :!: This cannot be used on Wayland currently
-  * :!: This expects ''amdgpu'' DDX driver to be used ((''modesetting'' has a 4K RB resolution without any settings require on Xorg))

-===== Deep Color =====
-  * The lack-of quotes around ''30'' is intentional and required syntax
-  * :!: This may cause minor issues with programs not expecting 30-bit color ((GpuTest's fur ring doesn't render right, RS's NXT client's splash screen is gray))
-  * :!: This can cause games in Wine to not start under some circumstances ((FFXIV crashes on start-up due to a DirectX error))
-  * There is no known benefit to enabling this as of 2019/10/22

-===== radeon =====
-  * Expects pre-SI GPUs ((HD6000 series and lower, and non-SI HD7000 series))
-  * For SI, CIK, and newer GPUs, use ''amdgpu'', along with enabling ''si_support'' and ''cik_support'' respectively for the ''amdgpu'' kernel module ((see ''modinfo -p amdgpu''))

-===== NVIDIA Proprietary =====
-==== Environment Variables ====
-  * Sets pre-rendered frames from the default to 1
-  * Apparently reduces CPU usage for desktop environments rendered with the NVIDIA GPU
-  echo 'export __GL_MaxFramesAllowed=1' | sudo tee '/etc/profile.d/nvidia-custom.sh' > '/dev/null' && cat '/etc/profile.d/nvidia-custom.sh'
-  sudo -e '/etc/profile.d/nvidia-custom.sh'
-==== Disable PRIME Render Offload ====
-  * [[http://download.nvidia.com/XFree86/Linux-x86_64/440.64/README/randr14.html|Offloading Graphics Display with RandR 1.4]]
-  * :!: Required if planning to use external displays
-  * :!: ''Coolbits'' is not required here, but may be useful
-  sudo cp -p '/usr/share/X11/xorg.conf.d/nvidia.conf' '/etc/X11/xorg.conf.d/nvidia.conf' && sudo -e '/etc/X11/xorg.conf.d/nvidia.conf'
