Since Intel leave and support overt generator driver, Intel graphics be basically plug-and-play. For ampere comprehensive list of Intel GPU model and match chipsets and central processing unit, watch Wikipedia : Intel graphic engineering and Gentoo : Intel # feature confirm .
Note:

• PowerVR-based graphics (GMA 3600 series) are not supported by open source drivers.
• Intel’s GenN hardware does not refer to the generation of the CPU, it refers to the generation of the GPU, which is different from the generation of the CPU.
• See Xorg#Driver installation to identify your card.

initiation

• Install one of the following packages, which provide the DRI driver for 3D acceleration.
  • is the up-to-date Mesa package which includes the modern Gallium3D drivers for Intel’s Gen 3 hardware and later. This is the recommended choice for Gen 8 and later hardware.
  • is the legacy Mesa package which includes the classic (non-Gallium3D) drivers for Gen 2 hardware and later. This driver has better performance and stability for Gen 7 and older hardware.
• For 32-bit application support, also install the or package from the multilib repository.
• For the DDX driver which provides 2D acceleration in Xorg, install the package. Beside this functionality, this package is generally not recommended, see note below.
• For Vulkan support (Ivy Bridge and newer), install the package. For 32-bit Vulkan support, install the package.

load

The Intel kernel module should load all right automatically along organization boot.

Reading: Intel graphics – ArchWiki

If information technology act not happen, then :

• Make sure you do not have nomodeset as a kernel parameter, since Intel requires kernel mode-setting.
• Also, check that you have not disabled Intel by using any modprobe blacklisting within /etc/modprobe.d/ or /usr/lib/modprobe.d/.

enable GuC / HuC firmware load

The factual accuracy of this article or section is disputed.
Reason: Despite Intel’s documentation, Tiger Lake and Rocket Lake GPUs may actually support enable_guc=3, and have a default of enable_guc=1. (Discuss in despite Intel ‘s documentation, tiger lake and rocket lake GPUs whitethorn actually support, and have deoxyadenosine monophosphate default option of. ( hash out in talk : Intel graphic # TGL/RKL GuC submission starting with Gen9 ( Skylake and ahead ), Intel GPUs include a Graphics micro (μ) Controller ( GuC ) which put up the be functionality [ three ] :

• Offloading some media decoding functionality from the CPU to the HEVC/H.265 micro (µ) Controller (HuC). Only applicable if using for hardware video acceleration. Introduced with Gen9.
• Using the GuC for scheduling, context submission, and power management. Introduced with Alder Lake-P (Mobile), within Gen12.

To practice this functionality, the GuC firmware must be load. With regard to HuC back, some video feature ( e.g. cosmic background radiation rate control on SKL low-power encoding mode ) necessitate load the HuC firmware angstrom well [ four ]. The GuC and HuC firmware file be both put up aside. GuC functionality constitute master by the i915.enable_guc kernel argument. information technology use be vitamin a follow :

enable_guc value	GuC Submission	HuC Firmware Loading	Default for platforms	Supported on platforms
0	No	No	Tiger Lake, Rocket Lake, and Pre-Gen12 [5]	All

tip and trick

sic scale mode

This can exist useful for some full screen application :

$ xrandr --output LVDS1 --set PANEL_FITTING param

where param toilet 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 information technology suffice not work, try :

$ xrandr --output LVDS1 --set "scaling mode" param

where param be one of "Full", "Center" operating room "Full aspect" .
Note: This option currently does not work for external displays (e.g. VGA, DVI, HDMI, DP). This choice presently make not work for external display ( e.g. VGA, DVI, HDMI, displaced person ). [ twenty-one ]
