First we need to find the iGPU type

lspci | grep VGA

This should return something like 00:02.0 VGA compatible controller: Intel Corporation Device 4e55 (rev 01)


Add the following to /etc/modprobe.d/i915.conf, replace 4e55 with your type

options i915 enable_guc=3
options i915 force_probe=4e55

Now to we need to rebuild the initramfs to add the above

update-initramfs -u


Install the required firmware files

  1. You need to enable the non-free source

  2. apt install -y firmware-misc-nonfree intel-media-va-driver-non-free


Now you should be good to reboot
