I just migrated my homelab server to a new one using a i5-13600K.
Evertyhing went smooth except for one thing, for some reason the iGPU drivers are not loaded e.g. /dev/dri is missing.
I do have video output but it seems to be using a generic fallback driver and I can't use it for hardware acceleration.
Manually loading the i915 module makes no difference.
Given that it even reports as "Intel Corporation Device a780" it seems to be missing support from the kernel ?
