The VIDEO_CARDS make.conf setting is used to define what graphics support is enabled on your system. It is generally used only by packages that directly implement graphics support, such as media-libs/mesa and a few others. To set VIDEO_CARDS, set it in /etc/make.conf, separating each value with a space, as follows:
/etc/make.conf (bash source code) VIDEO_CARDS="intel i965 i915"
Funtoo Differences
Starting with Funtoo Linux 1.4, VIDEO_CARDS settings work a bit differently than in Gentoo and are documented here. Also note that it is possible to have VIDEO_CARDS set for you via use of a Funtoo profile mix-in.
The Funtoo VIDEO_CARDS flags are designed to have a consistent format. If just a graphics driver is listed, such as i965, then it is an X-based DRI driver. Drivers that use the new Gallium driver architecture are in the format gallium-<driver> such as gallium-radeonsi. In addition, any optional framework is listed as a prefix, such as vulkan-i965 for optional DRI-based Vulkan support for i965+ Intel cards.
Use within Ebuilds
Inside ebuilds, the VIDEO_CARDS settings is USE_EXPANDed to a USE flag with a prefix of video_card_. For example, radeonsi will set the video_card_radeonsi USE flag, gallium-osmesa will set the video_card_gallium-osmesa USE flag, etc. Pay careful attention to the use of underscores and hyphens. Hyphens are used in the video card variable name itself, whereas underscores are used in video_card_ only.
Use within Make.conf
Typically, VIDEO_CARDS settings are "stacked", which means that multiple related flags are specified. Here are some common examples:
/etc/make.conf (bash source code) # This setting will support nearly all X/DRI-based Intel integrated graphics:
VIDEO_CARDS="intel dri3 i965 i915"
# This next setting is similar to the one above but will also enable Vulkan support:
VIDEO_CARDS="intel dri3 i965 vulkan-i965 i915"
# This next setting will enable Gallium for Intel integrated graphics -- The Intel drivers are currently more mature for X/DRI, though:
VIDEO_CARDS="intel gallium gallium-i915"
# This next setting could be useful if you have hybrid graphics on your laptop and you plan to use X:
VIDEO_CARDS="intel dri3 i965 i915 nvidia"
# This setting would be good for X-based graphics with Radeon cards using gallium:
VIDEO_CARDS="radeon gallium gallium-r300 gallium-r600 gallium-radeonsi"
VIDEO_CARDS Settings
The most-common VIDEO_CARDS settings are listed below. For a comprehensive list of settings, type emerge -av mesa and peruse the list of USE flags.
