That is about how to re-install gnome shell. This problem sems to be
way below gnome-shell. But I will give it a go anyway; perhaps
installing gnome-shell installs the entire video subsystem it needs.
Have you checked your disk for errors with `fsck`?
No - but it's been rebooted a few times, which I thought did a check.
I'll check the check :-)

If you have a hint on how I can tell the difference I will do it
immediately and report. But I'll google a bit more too.
