The purpose of this page is to give you streamlined steps for setting up your video hardware for X, and desktop environments such as GNOME.

{{Important|Editors: OK, I've decided to change the plans for this page. This is going to be a page similar to [[Subarches]]. 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 <code>eselect opengl</code> 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.}}

An overview of each driver follows:
 
 
=== AMD/ATI ===
 
 
Users can choose between free ({{Package|x11-drivers/xf86-video-ati}}) and proprietary ({{Package|x11-drivers/ati-drivers}}) video drivers.  {{Package|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 {{Package|x11-drivers/xf86-video-ati}} has an official [http://xorg.freedesktop.org/wiki/RadeonFeature/ 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 ({{package|x11-drivers/xf86-video-intel}} supports [[Wikipedia:Intel_GMA|Intel GMA]] and [[Wikipedia:Intel_HD_and_Iris_Graphics|Intel HD]] graphics processors, which are found in laptops and desktop systems.
 
 
=== NVIDIA ===
 
 
Users can choose between {{Package|x11-drivers/xf86-video-nouveau}} and proprietary {{package|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.

  • The description given in the "description" column is rather short, often it is best to try it your self and see what it actually does.
  • Even if not specified in the "command" column, most commands fired in normal mode accept a "<num> prefix" (Eg. `5w` is equivalent to `wwwww`).
  • Most commands will work in visual mode as well as in normal mode.

Deplacements

command meaning description
w word move to next word
