To choose the right driver, first detect the graphics card. lspci can be used for this task:
lspci | grep -i VGA
This should show something like this:
lspci | grep -i VGA
00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09)
The lspci output for the graphics controller may refer to CPU generations, whereas the Feature support table below refers to GPU generations. E.g., “3rd Gen” in the example lspci output above corresponds to “Gen7” in the table below.

emerge --ask sys-kernel/linux-firmware
Otherwise errors such as the following might be visible in dmesg:
kernel: i915 0000:00:02.0: Direct firmware load for i915/skl_dmc_ver1_26.bin failed with error -2 kernel: i915 0000:00:02.0: Failed to load DMC firmware [https://01.org/linuxgraphics/intel-linux-graphics-firmwares], disabling runtime power management.
Include the files required for the GPU in the kernel, in this case:
Device Drivers ---> Generic Driver Options ---> -*- Userspace firmware loading support [*] Include in-kernel firmware blobs in kernel binary (i915/skl_dmc_ver1_26.bin) External firmware blobs to build into the kernel binary (/lib/firmware) Firmware blobs root directory
Including the firmware in-kernel may cause suspend-to-ram to fail, if this is a concern don't include the blob built into the kernel.
It is possible to add GuC firmware, too, but there are problems with it, so it won’t be loaded by default (passing additional parameters is needed). It’s actually for kernel 4.8.7 at least.
Please note that the firmware file name should match the one from MODULE_FIRMWARE in the source tree. Now it is
i915/skl_dmc_ver1.bin) for DMC firmware. To check this for GuC and DMC firmware type the following command within Linux source:
grep -B 1 'MODULE_FIRMWARE.*SKL' drivers/gpu/drm/i915/intel_guc_loader.c drivers/gpu/drm/i915/intel_csr.c
drivers/gpu/drm/i915/intel_guc_loader.c-#define I915_SKL_GUC_UCODE "i915/skl_guc_ver6_1.bin" drivers/gpu/drm/i915/intel_guc_loader.c:MODULE_FIRMWARE(I915_SKL_GUC_UCODE); -- drivers/gpu/drm/i915/intel_csr.c-#define I915_CSR_SKL "i915/skl_dmc_ver1_26.bin" drivers/gpu/drm/i915/intel_csr.c:MODULE_FIRMWARE(I915_CSR_SKL);
To enable GuC in older kernels (around 4.14), add kernel parameters
i915.enable_guc_loading=1 i915.enable_guc_submission=1. For more recent versions (at least including 4.17), add
enable_guc=2. For the exact parameter options, see
The following kernel options need to be activated:
Processor type and features ---> [*] MTRR (Memory Type Range Register) support Device Drivers ---> Graphics support ---> <*> /dev/agpgart (AGP Support) ---> <*> Intel 440LX/BX/GX, I8xx and E7x05 chipset support <*> Direct Rendering Manager (XFree86 4.1.0 and higher DRI support) ---> <*> Intel 8xx/9xx/G3x/G4x/HD Graphics [*] Enable modesetting on intel by default [*] Enable legacy fbdev support for the modesetting intel driver
The legacy fbdev support is required since kernel 3.14.14 at least for i915 (
For hybrid Intel/AMD system, follow also the steps of radeon (open source) or fglrx (closed binary) drivers.
Since kernel version 4.4 the driver has been moved and the legacy fbdev support is now

Kernel version 4.18 or later is recommended for Coffee Lake because it will work without enabling alpha support. Kernel 4.14 requires loading module i915 with alpha_support=1 or enabling
CONFIG_DRM_I915_ALPHA_SUPPORTin kernel config.
Portage uses the VIDEO_CARDS variable, which expands into the USE_EXPAND variable, for enabling support for various graphics cards. Assuming the x11-base/xorg-drivers package has already been installed, setting the VIDEO_CARDS variable in /etc/portage/make.conf will pull in the correct video driver:
Beginning with x11-base/xorg-drivers-1.19, the x11-base/xorg-drivers package (in addition to the mesa package) includes support for the
i965USE flag. This will omit selection of the deprecating x11-drivers/xf86-video-intel driver in favor of the more maintained, generic modesetting DDX driver built into x11-base/xorg-server.
After making any make.conf modifications, update the system so the changes take effect by passing the
--changed-use --deep options to emerge:
emerge --ask --changed-use --deep @world
Those wishing to not accept the Intel graphic driver defaults in the main repository can read on into the sub-sections below.
Before proceeding with the Intel DDX driver, note that this driver has been slowly deprecating for several years. This has caused other major Linux distributions to begin to move toward the modesetting DDX driver (detailed in the section below). Although presently faster than modesetting driver, there has been no official package release from Intel upstream for their DDX driver for quite some time, and is therefore causing a maintenance burden on Gentoo's X11 package maintainers.
With this being stated, the Intel DDX driver has slight speed advantages over the generic modesetting driver as it is able to more closely interact with hardware acceleration present in chips utilizing SNA and DRI3.
Check the USE flags of x11-drivers/xf86-video-intel:
USE flags for x11-drivers/xf86-video-intel X.Org driver for Intel cards
||Enable direct rendering: used for accelerated 3D and some 2D, like DMA|
||Use DRI3 by default|
||Enable SandyBridge's New Acceleration (useful on all chipsets, not just SandyBridge)|
||Build the intel-virtual-output tool|
||Enable UMA Acceleration Architecture|
||Enables X-Video Motion Compensation support|
emerge --ask x11-drivers/xf86-video-intel
To force Xorg server to use the Intel DDX driver with SNA for hardware accelleration, the following file can be created in /etc/X11/xorg.conf.d/:
Section "Device" Identifier "Intel Graphics" Driver "intel" Option "AccelMethod" "sna" EndSection
As mentioned above, the modesetting DDX driver is now the default driver on newer Intel graphics chipsets for Gentoo. This driver uses GLAMOR to accelerate 2D graphical over Mesa (the open source OpenGL implementation). As of x11-base/xorg-drivers-1.19, this has become the default for Gentoo.
To force the modesetting driver, first make sure
glamor has been added to the USE variable:
USE="glamor" VIDEO_CARDS="intel i965"
emerge --ask --changed-use --deep @world
Now force Xorg server to load the modesetting driver:
Section "Device" Identifier "Intel Graphics" Driver "modesetting" Option "AccelMethod" "glamor" Option "DRI" "3" EndSection
Note, if both 20-intel.conf and 20-modesetting.conf are defined in /etc/X11/xorg.conf.d/, the X server will attempt to load the files in alpha-numeric order.
Intel GMA X4500HD / G45 / GM45 and newer supports VAAPI hardware video acceleration.
As of November 15th, 2016 Vulkan is supported in the main ebuild repository for Intel Core processors using the i965 mesa driver.
Please note, that this will build a working Vulkan driver, but it will not provide a libvulkan.so.1, but a drivers-specific libvulkan_intel.so. The package media-libs/vulkan-loader provides libvulkan.so.1.
Various utilities useful for debugging are provided by x11-apps/igt-gpu-tools package.
For example GPU min/max/current frequency can by displayed by:
acl USE flag is enabled globally and ConsoleKit is being used (default for desktop profiles) permissions to video cards will be handled automatically. It is possible to check the permissions using getfacl:
getfacl /dev/dri/card0 | grep larry
A broader solution is to add the user(s) needing access the video card to the video group:
gpasswd -a larry video
Note that users will be able to run X without permission to the DRI subsystem, but acceleration will be disabled.
Choose one of the following configuration options:
- Classic Driver -- x11-drivers/xf86-video-intel
- As xorg is not aware of i915 or i965 they will need to be addressed as Driver
Section "Device" Identifier "intel" Driver "intel" EndSection
- Alternate Driver for Gen 4+ -- Modesetting
Experiences of this configuration can be found in the Discussion of this page. Add any difficulties there so this section can be improved.
- As of xorg-server-1.17, the modesetting driver was moved into x11-base/xorg-server. This driver has more features than the classic driver, such as the ability to support acceleration via GLAMOR.
- This configuration is the default for
VIDEO_CARDS="intel i965"beginning with x11-base/xorg-drivers-1.19. If you wish to use the classic driver, you will need to install x11-drivers/xf86-video-intel manually:
emerge --ask x11-drivers/xf86-video-intel
- xorg-server is easily configured to prefer
modesettingover the older
Section "Device" Identifier "modesetting" Driver "modesetting" EndSection
The X server is designed to work out-of-the-box, with no need to manually edit X.Org's configuration files. It should detect and configure devices such as displays, keyboards, and mice.
However, the main configuration file of the X server is the xorg.conf.

HTML5/VAAPI GPU hangs
If the GPU hangs up when watching VAAPI-accelerated video (e.g. on YouTube) try enabling IOMMU:
Device Drivers ---> [*] IOMMU Hardware Support ---> [*] Support for Intel IOMMU using DMA Remapping Devices [*] Enable Intel DMA Remapping Devices by default

A workaround is to set
TerminateServer=true in all sections of the file /usr/share/config/kdm/kdmrc, which starts with
KDE's plasma eating CPU
If /usr/bin/plasmashell is always consuming several percent of CPU, perhaps this is related to a vsync problem. QT Quick Animation seem to loop too fast when vsync is not managed by the driver (Reference).
A way to enable vsync with SNA is to enable the
TearFree option in xorg.conf:
Section "Device" Identifier "Device0" Driver "intel" Option "AccelMethod" "SNA" Option "TearFree" "true" EndSection

- According to this Debian wiki, CONFIG_FRAMEBUFFER_CONSOLE must be set to y (aka built-in to the kernel). Otherwise, it is possible to always have a black screen unless
nomodesetis passed to the kernel, thus disabling kernel mode setting (KMS).
acpi_osi="Linux"can be passed to the kernel command line to try to solve this kind of issue. This is usually done through the bootloader.
- Kernel with version 4.2 or newer is needed with some 8th generation chipsets.
Brightness does not change with keyboard shortcuts
First, make sure vendor compatibility is on in the kernel configuration. Toshiba for Toshiba, etc.
If it is, or when the brightness buttons are working, the issue is that the kernel can not detect where the brightness control is located.
Luckily, this is easy enough to modify, as long as the kernel version is >= 3.13.x and < 4.2.
Add the following argument to the kernel command-line:
On kernels >= 4.2, the video.use_native_backlight option is no longer available. You should use one of the following instead (experiment to see which works on your system):
Do your key bindings map to actions viewable in xev? Can you adjust the screen brightness using xbacklight? You can always do a work around via a keyboard remapping. For LXDE it can be done via:
<keybind key="XF86MonBrightnessUp"> <action name="Execute"> <command>xbacklight +5</command> </action> </keybind> <keybind key="XF86MonBrightnessDown"> <action name="Execute"> <command>xbacklight -5</command> </action> </keybind>
Using the Modesetting DDX, the x11-apps/xbacklight package will not work. Use sys-power/acpilight for a compatible interface.
White or missing textures in games
This is most likely caused by missing S3TC support. Possible solutions:
- Either set
force_s3tc_enableenvironment variable to
true, or enable this option in ~/.drirc (using x11-misc/driconf):
emerge --ask --oneshot x11-misc/driconf
- Install media-libs/libtxc_dxtn. On amd64, it might be a good idea to enable 32-bit build of this library since many games might be shipping 32-bit executables:
emerge --ask media-libs/libtxc_dxtn
