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.

Video Acceleration

The following VIDEO_CARDS settings are exclusive to Funtoo, and are safe to enable on all systems. They instruct Mesa to enable the related video acceleration technology in the driver if it is available:

xa
Enable XA X Acceleration API
vaapi
Enable VA/VAAPI support
vdpau
Enable VDPAU support
xvmc
Enable XVMC support

Therefore, it is safe, and recommended, to append all these settings to your VIDEO_CARDS setting, which can be done by adding this to the end of your /etc/make.conf:

   /etc/make.conf (bash source code)
VIDEO_CARDS="${VIDEO_CARDS} xa vaapi vdpau xvmc"

If you are using the workstation or desktop flavor, these settings will be enabled for you automatically.

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"
