The idea is to help people to identify their hardware and guide them toward the correct driver for their chipset. The focus will be primarily on defining the types of hardware that are supported, what products they appear in, and how to know if you have this hardware, and also give people good general overview of options available to them (free vs. proprietary, etc.) Other important topics that apply to all drivers, like {{c|eselect opengl}} should be covered as well. This will then serve as the meta-page for Video support, with individual ebuild pages holding the details for each driver.}}

Video Driver Selection

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

Run ego profile mix-ins get see what profiles are currently selected, and ego profile mix-ins +NEW-DRIVER -OLD-DRIVER to add and remove your VIDEO-CARDS as you like. You'll need to emerge @world and --depclean for your changes to reflect


Selecting a Video Driver

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

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.
