# Run the [[Alpine setup scripts#setup-xorg-base|setup-xorg-base]] script.
For all Intel Graphics up to Haswell, the user must manually select '''crocus''' Mesa driver in order to let the graphics work properly:
# Install the Xorg Intel video drivers: {{Cmd|apk add xf86-video-intel}}
# Enable [[#Kernel Modesetting (KMS)]]. Specifically, the <code>fbcon</code> module is necessary, or leaving Xorg (via <code>Ctrl+Alt+F1</code> or quitting) will result in a black screen until the machine is power cycled. If you have already launch Xorg and don't want to experience this effect, you can <code>modprobe fbcon</code> while Xorg is running.

To enable KMS at boot:
For newer Intel Graphics, if automatic driver selection does not work and bugs such as missing mouse cursor under [[Sway]] occur (no hardware graphics acceleration), the user can manually select '''iris''' driver:
# Add the <code>i915</code> and <code>fbcon</code> modules to {{Path|/etc/modules}}: {{Cmd|$ echo i915 >> /etc/modules<br />$ echo fbcon >> /etc/modules}}
# Install <code>mkinitfs</code>: {{Cmd|apk add mkinitfs}}
# Enable the <code>kms</code> feature in the <code>mkinitfs</code> configuration by adding it to the <var>features</var> variable, e.g., {{cat|/etc/mkinitfs/mkinitfs.conf|features{{=}}"keymap cryptsetup kms ata base ide scsi usb virtio ext4"}}
# Run <code>mkinitfs</code>.

Install the following packages as needed:

  • mesa-dri-gallium: necessary Mesa drivers for all Intel Graphics.
  • mesa-va-gallium: Mesa vaapi drivers for all Intel video decoding acceleration. You want one of the below too.
  • intel-media-driver: VAAPI driver, for hardware accelerated video encoding and decoding. What you want since Intel Broadwell.
  • libva-intel-driver: VAAPI driver, for processors older than Broadwell.
  • linux-firmware-i915: Needed if the i915 driver complains about firmware being missing in dmesg
  • xf86-video-intel: Legacy X.org driver with known Issues. Not recommended, use this only if nothing else works.

Note

For all Intel Graphics up to Haswell, the user must manually select crocus Mesa driver in order to let the graphics work properly:

export MESA_LOADER_DRIVER_OVERRIDE=crocus

For newer Intel Graphics, if automatic driver selection does not work and bugs such as missing mouse cursor under Sway occur (no hardware graphics acceleration), the user can manually select iris driver:

export MESA_LOADER_DRIVER_OVERRIDE=iris
