Can you show "pciconf -l | fgrep vga" output? 22.4.3 has some Gen12
support (including Alder Lake) but probably not your iGPU.

libva-intel-media-driver update is currently out-of-date due to
complication when rebasing patches for FreeBSD support. I still
use Skylake iGPU, so it is low priority.

It's part of probing Wayland connection. X11 hardcodes /tmp/.X11-unix
as the directory for its unix(4) sockets but Wayland uses XDG_RUNTIME_DIR.
For example,
- DISPLAY=:0 refers to /tmp/.X11-unix/X0
- WAYLAND_DISPLAY=wayland-0 refers to $XDG_RUNTIME_DIR/wayland-0
