this page needs framebuffering and console resolution information.

Warning

This page is hot garbage, and has not been updated since 2016. DO NOT put video card statements in make.conf use Funtoo_Profiles instead.

Video Driver Installation and Setup

Individual driver pages cover specific setup steps for each driver. The general process is as follows:

Define VIDEO_CARDS variable in /etc/portage/make.conf to refer to the name of the driver that you wish to use. Special names, rather than ebuild package names are used. For example, fglrx is used to refer to x11-drivers/ati-drivers.
Update your system using emerge, if X is already installed, or emerge xorg-x11. Your VIDEO_CARDS settings will result in your selected drivers being installed.
Configure X to use these drivers. This often involves running X -configure or using a supplied tool to produce an initial X configuration like aticonfig --initial.
If necessary (this is typically done automatically for you,) run eselect opengl and eselect opencl to set the working OpenGL and OpenCL implementation.

Selecting a Video Driver

First determine which video card you have and which driver it requires.

root # lspci -nn

Once hardware is determined use the following sections to add or edit the VIDEO_CARDS global variable in /etc/portage/make.conf. See the specific driver pages for more granular details including kernel configurations, frame buffer settings, and X configuration.

Package Name	License	Developed by	`VIDEO_CARDS` setting
`x11-drivers/xf86-video-ati`	Open Source	Community	`radeon, radeonsi`
`x11-drivers/ati-drivers`	Proprietary	AMD	`fglrx`
No results	Open Source	Intel	`intel, intel i915, intel i965`
`x11-drivers/xf86-video-nouveau`	Open Source	Community	`nouveau`
`x11-drivers/nvidia-drivers`	Proprietary	NVIDIA	`nvidia`
No results	Open Source	Community	`vesa`
No results	Open Source	Community	`vga`

An overview of each driver follows:

AMD/ATI

Users can choose between free (x11-drivers/xf86-video-ati) and proprietary (x11-drivers/ati-drivers) video drivers. x11-drivers/ati-drivers supports a variety AMD products, including Radeon R9, R7, R5 and HD 5000 Series through HD 8000 Series. Also supported are AMD A-Series APUs and Mobile Radeon HD chipsets. The free x11-drivers/xf86-video-ati has an official hardware and feature compatibility matrix. The free drivers are recommended as the proprietary drivers are not currently maintained very well by AMD. Users of AMD Southern & Sea Islands (HD7750 and above) should enable radeonsi for better performance and functionality.

Intel

The Intel video driver (No results supports Intel GMA and Intel HD graphics processors, which are found in laptops and desktop systems.

NVIDIA

Users can choose between x11-drivers/xf86-video-nouveau and proprietary x11-drivers/nvidia-drivers video drivers released by NVIDIA. The proprietary drivers have a reputation for quality, although they are often not updated to work with the latest versions of X or the Linux kernel.
