Public bug reported:
The screen brightness is stuck at 50% of the max output and the
brightness controls/slider do nothing at all.
This issue started happening with the nvidia-driver-470 package even
before I upgraded from 21.04, and it doesn't happen with 465. The bug
manifests in both X11 and Wayland. (and GDM itself before logging in)
Setting nvidia-drm.modeset to 1 doesn't seem to affect it either.
