Public bug reported:

After some update (unfortunately I'm not sure what) if I try to play a
videofile (e.g. mpv movie.mkv) I get this error:

libGL error: failed to open drm device: Permission denied

I think from this message is not very clear why is that.

I figured out I was not in "video" group: "id user_name"

I had to do this: "usermod -aG video user_name " and then restart X
(logout, login). After that it works again.

So I suspect there is some problem there. Why libGL cannot be used
without membership in video group or why a regular user is not in video
group.
