Each kernel of necessity must get its own device driver set. xserver-xorg-video-intel provides the intel display driver for X (DDX; hardware Device Dependent X), which when installed will be used by Xorg/Wayland in lieu of the default/preferred modesetting display driver for X (DIX: hardware Device Independent X). Also involved in graphics are Mesa-dri and libdrm_intel1. > - xserver-xorg-core > - xserver-xorg-video-all > - and some other xserver-xorg-video...
