Bug description:
Several schools reported black screens after normally updating their
Ubuntu boxes from 18.0.5-0ubuntu0~18.04.1 to 18.2.2-0ubuntu1~18.04.1.
Downgrading mesa fixes the problem.

Unfortunately I can't find a lot of useful information, here are some bits:
* systemctl --failed says "gpu-manager" and "lightdm" have failed
* Xorg.log is clean: https://termbin.com/6l2b
* dmesg too: https://termbin.com/ip4e
* It happens on lightdm/MATE, I don't know about Ubuntu GNOME.
* If one runs `xinit` from ssh, it fails with:
i965: Failed to submit batchbuffer: Invalid argument
