Since Intel provides and supports open source drivers, Intel graphics are essentially plug-and-play.
For a comprehensive list of Intel GPU models and corresponding chipsets and CPUs, see this comparison on Wikipedia.
Install the package, which provides the DRI driver for 3D acceleration.
- For 32-bit application support on x86_64, also install multilib. from
- For the DDX driver (which provides 2D acceleration in Xorg), install the package. (Often not recommended, see note below.)
- For Vulkan support (Ivy Bridge and newer), install the package.
Also see Hardware video acceleration.
The Intel kernel module should load fine automatically on system boot.
If it does not happen, then:
- Make sure you do not have
vga=as a kernel parameter, since Intel requires kernel mode-setting.
- Also, check that you have not disabled Intel by using any modprobe blacklisting within
Enable early KMS
Kernel mode setting (KMS) is supported by Intel chipsets that use the i915 DRM driver and is mandatory and enabled by default.
Refer to Kernel mode setting#Early KMS start for instuctions on how to enable KMS as soon as possible at the boot process.
There is no need for any configuration to run Xorg.
However, to take advantage of some driver options, you will need to create a Xorg configuration file similar to the one below:
Section "Device" Identifier "Intel Graphics" Driver "intel" EndSection
Additional options are added by the user on new lines below
For the full list of options, see the man page for
Module-based Powersaving Options
i915 kernel module allows for configuration via module options. Some of the module options impact power saving.
A list of all options along with short descriptions and default values can be generated with the following command:
$ modinfo -p i915
To check which options are currently enabled, run
# systool -m i915 -av
You will note that many options default to -1, resulting in per-chip powersaving defaults. It is however possible to configure more aggressive powersaving by using module options.
The following set of options should be generally safe to enable:
options i915 enable_rc6=1 enable_fbc=1 semaphores=1
RC6 sleep modes (enable_rc6)
You can experiment with higher values for
enable_rc6, but your GPU may not support them or the activation of the other options .
enable_rc6 values are a bitmask with bit values RC6=1, RC6p=2, RC6pp=4 - where "RC6p" and "RC6pp" are lower power states.
To confirm the current running RC6 level, you can look in sysfs:
# cat /sys/class/drm/card0/power/rc6_enable
... if the value read is a lower number than expected, the other RC6 level are probably not supported. Passing
drm.debug=0xe will add DRM debugging information to the kernel log - possibly including a line like this:
[drm:sanitize_rc6_option] Adjusting RC6 mask to 1 (requested 7, valid 1)
Framebuffer compression (enable_fbc)
Framebuffer compression may be unreliable or unavailable on Intel GPU generations before Sandy Bridge (generation 6). This results in messages logged to the system journal similar to this one:
kernel: drm: not enough stolen space for compressed buffer, disabling.
Tips and tricks
The SNA acceleration method causes tearing for some people. To fix this, enable the
"TearFree" option in the driver by adding the following line to your configuration file:
Option "TearFree" "true"
See the original bug report for more info.
Disable Vertical Synchronization (VSYNC)
The intel-driver uses Triple Buffering for vertical synchronization, this allows for full performance and avoids tearing. To turn vertical synchronization off (e.g. for benchmarking) use this
.drirc in your home directory:
<device screen="0" driver="dri2"> <application name="Default"> <option name="vblank_mode" value="0"/> </application> </device>
Setting scaling mode
This can be useful for some full screen applications:
$ xrandr --output LVDS1 --set PANEL_FITTING param
param can be:
center: resolution will be kept exactly as defined, no scaling will be made,
full: scale the resolution so it uses the entire screen or
full_aspect: scale the resolution to the maximum possible but keep the aspect ratio.
If it does not work, try:
$ xrandr --output LVDS1 --set "scaling mode" param
param is one of
KMS Issue: console is limited to small area
One of the low-resolution video ports may be enabled on boot which is causing the terminal to utilize a small area of the screen. To fix, explicitly disable the port with an i915 module setting with
video=SVIDEO-1:d in the kernel command line parameter in the bootloader. See Kernel parameters for more info.
If that does not work, try disabling TV1 or VGA1 instead of SVIDEO-1.
Determine active video ports
In order to find active video ports you might want to disable with the video kernel parameter, you should look at the direct rendering manager module in sysfs:
$ ls -l /sys/class/drm/ total 0 lrwxrwxrwx 1 root root 0 May 17 11:03 card0 -> ../../devices/pci0000:00/0000:00:02.0/drm/card0 lrwxrwxrwx 1 root root 0 May 17 11:03 card0-DP-1 -> ../../devices/pci0000:00/0000:00:02.0/drm/card0/card0-DP-1 lrwxrwxrwx 1 root root 0 May 17 11:03 card0-DP-2 -> ../../devices/pci0000:00/0000:00:02.0/drm/card0/card0-DP-2 lrwxrwxrwx 1 root root 0 May 17 11:03 card0-eDP-1 -> ../../devices/pci0000:00/0000:00:02.0/drm/card0/card0-eDP-1 lrwxrwxrwx 1 root root 0 May 17 11:03 card0-HDMI-A-1 -> ../../devices/pci0000:00/0000:00:02.0/drm/card0/card0-HDMI-A-1 lrwxrwxrwx 1 root root 0 May 17 11:03 card0-HDMI-A-2 -> ../../devices/pci0000:00/0000:00:02.0/drm/card0/card0-HDMI-A-2 lrwxrwxrwx 1 root root 0 May 17 11:03 card0-HDMI-A-3 -> ../../devices/pci0000:00/0000:00:02.0/drm/card0/card0-HDMI-A-3 lrwxrwxrwx 1 root root 0 May 17 11:03 controlD64 -> ../../devices/pci0000:00/0000:00:02.0/drm/controlD64 lrwxrwxrwx 1 root root 0 May 17 11:03 renderD128 -> ../../devices/pci0000:00/0000:00:02.0/drm/renderD128 -r--r--r-- 1 root root 4096 May 17 11:03 version
To see the status of the respective ports:
$ grep . /sys/class/drm/card?-*/status /sys/class/drm/card0-DP-1/status:disconnected /sys/class/drm/card0-DP-2/status:disconnected /sys/class/drm/card0-eDP-1/status:disconnected /sys/class/drm/card0-HDMI-A-1/status:disconnected /sys/class/drm/card0-HDMI-A-2/status:disconnected /sys/class/drm/card0-HDMI-A-3/status:connected
If you find any video ports connected, which you are not aware of or you do not want to be serviced, include its identifier (the part after the
cardN- item) in the above
video= parameter, e.g.
video=HDMI-A-3:d to disable the HDMI-A-3 port connected above.
H.264 decoding on GMA 4500
The . This is echoed by other experiences . Setting the preallocated video ram size higher in bios results in much better hardware decoded playback. Even 1080p h264 works well if this is done. Smooth playback (1080p/720p) works also with AUR in combination with AUR and AUR. With MPV and the Firefox plugin "Watch with MPV" it is possible to watch hardware accelerated YouTube videos.package provides MPEG-2 decoding only for GMA 4500 series GPUs. The H.264 decoding support is maintained in a separated g45-h264 branch, which can be used by installing AUR package. Note however that this support is experimental and its development has been abandoned. Using the VA-API with this driver on a GMA 4500 series GPU will offload the CPU but may not result in as smooth a playback as non-accelerated playback. Tests using mplayer showed that using vaapi to play back an H.264 encoded 1080p video halved the CPU load (compared to the XV overlay) but resulted in very choppy playback, while 720p worked reasonably well
Setting brightness and gamma
SNA is the default acceleration method in configuration file:. If you are experience issues with SNA (e.g. pixelated graphics, corrupt text, etc.), try using UXA instead, which can be done by adding the following line to your
Option "AccelMethod" "uxa"
man 4 intel under
Option "DRI" "2"
modesetting driver, this method of disabling DRI3 does not work. Instead, one can set the environment variable
Font and screen corruption in GTK+ applications (missing glyphs after suspend/resume)
Should you experience missing font glyphs in GTK+ applications, the following workaround might help. Edit
/etc/environment to add the following line:
See also FreeDesktop bug 88584.
Blank screen during boot, when "Loading modules"
If using "late start" KMS and the screen goes blank when "Loading modules", it may help to add
intel_agp to the initramfs. See Kernel mode setting#Early KMS start section.
Alternatively, appending the following kernel parameter seems to work as well:
If you need to output to VGA then try this:
X freeze/crash with intel driver
Some issues with X crashing, GPU hanging, or problems with X freezing, can be fixed by disabling the GPU usage with the
NoAccel option - add the following lines to your configuration file:
Option "NoAccel" "True"
Alternatively, try to disable the 3D acceleration only with the
Option "DRI" "False"
If you experience crashes and have
Option "TearFree" "true" Option "AccelMethod" "sna"
in your configuration file, in most cases these can be fixed by adding
to your boot parameters.
If you are using kernel 4.0.X or above on Baytrail architecture and frequently encounter complete system freezes (especially when watching video or using GFX intensivelly), you should try adding the following kernel option as a workaround, until this bug will be fixed permanently.
Adding undetected resolutions
This issue is covered on the Xrandr page.
Weathered colors (color range problem)
Kernel 3.9 contains a new default "Automatic" mode for the "Broadcast RGB" property in the Intel driver. It is almost equivalent to "Limited 16:235" (instead of the old default "Full") whenever an HDMI/DP output is in a CEA mode. If a monitor does not support signal in limited color range, it will cause weathered colors.
One can force mode e.g.
xrandr --output <HDMI> --set "Broadcast RGB" "Full" (replace
<HDMI> with the appropriate output device, verify by running
Unfortunately, the Intel driver does not support setting the color range through an
xorg.conf.d configuration file.
A bug report is filed and a patch can be found in the attachment.
Backlight is not adjustable
If after resuming from suspend, the hotkeys for changing the screen brightness do not take effect, check your configuration against the Backlight article.
If the problem persists, try one of the following kernel parameters:
acpi_osi=Linux acpi_osi="!Windows 2012" acpi_osi=
Disabling frame buffer compression
Enabling frame buffer compression on pre-Sandy Bridge CPUs results in endless error messages:
$ dmesg |tail [ 2360.475430] [drm] not enough stolen space for compressed buffer (need 4325376 bytes), disabling [ 2360.475437] [drm] hint: you may be able to increase stolen memory size in the BIOS to avoid this
The solution is to disable frame buffer compression which will imperceptibly increase power consumption (around 0.06 W). In order to disable it add
i915.enable_fbc=0 to the kernel line parameters. More information on the results of disabled compression can be found here.
Corruption/Unresponsiveness in Chromium and Firefox
If you experience corruption or unresponsiveness in Chromium and/or Firefox set the AccelMethod to "uxa".
Kernel crashing w/kernels 4.0+ on Broadwell/Core-M chips
A few seconds after X/Wayland loads the machine will freeze and journalctl will log a kernel crash referencing the Intel graphics as below:

This can be fixed by disabling execlist support which was changed to default on with kernel 4.0. Add the following kernel parameter:
This is known to be broken to at least kernel 4.0.5.
The i915 DRM driver is known to cause various GPU hangs, crashes and even full system freezes. It might be necessary to disable hardware acceleration to workaround these issues. One solution is to use the following Xorg configuration.
Section "Device" Identifier "Intel Graphics" Driver "intel" Option "DRI" "false" EndSection
Otherwise, specific applications such as Chromium and Firefox browsers can be instructed to disable hardware rendering directly.
Another option that seems to work for some users is to add the
i915.enable_rc6=0 kernel boot parameter, which will cause the CPU/GPU to remain in high-power modes, but seems to resolve most cases of GPU hangs and system freezes.
Lag in Windows guests
The video output of a Windows guest in VirtualBox sometimes hangs until the host forces a screen update (e.g. by moving the mouse cursor). Removing the
enable_fbc=1 option fixes this issue.
The following power saving features used by intel iGPUs are known to cause flickering in some instances. A temporary solution is to disable one of them using the appropriate kernel boot parameter option:
- Rc6 sleep modes (see #RC6 sleep modes (enable_rc6)), can be disabled with
