What is xf86-video-intel

The xf86-video-intel module is an open-source 2D graphics driver for the X Window System as implemented by X.org.

It supports a variety of Intel graphics chipsets including:

	i810/i810e/i810-dc100,i815,
	i830M,845G,852GM,855GM,865G,
	915G/GM,945G/GM/GME,946GZ
	G/GM/GME/Q965,
	G/Q33,G/Q35,G41,G/Q43,G/GM/Q45
	PineView-M (Atom N400 series)
	PineView-D (Atom D400/D500 series)
	Intel(R) HD Graphics,
	Intel(R) Iris(TM) Graphics,
	Intel(R) Iris(TM) Pro Graphics.

Where to get more information about the driver

The primary source of information about this and other open-source drivers for Intel graphics is: https://01.org/linuxgraphics/

Documentation specific to the xf86-video-intel driver including possible configuration options for the xorg.conf file can be found in the intel(4) manual page. After installing the driver this documentation can be read with the following command:

	man intel

Notable changes over the regular xf86-video-intel implementation.

1. Fix for screen freezing if using PRIME and a secondary graphics card.
2. Restoration and clean up of legacy options.
3. Improved performance with the BLT (blitter) engine on Gen 7.x (Ivy Bridge/Haswell) era hardware when mitigations are disabled.

Known issues.

Broken hardware acceleration (EGL only) when using Nvidia drivers.

Fixed in master branch as of November 7th 2024.

Lack of support on newer hardware.

Generation 11 (Ice Lake) and newer graphics are not supported.

There are mostly no plans to address this, a solution is to use the modesetting driver included within X.Org.

Applications hang with the NVIDIA driver via PRIME.

SNA is completely broken at the moment with the NVIDIA driver, the following solutions may work:

1. Use modesetting or uxa on your iGPU
2. Use modesetting for both iGPU and dGPU [1]
3. Use Wayland.

[1] Requires a modified version of modesetting that correctly handles the NVIDIA driver.
