Public bug reported:
After running software update on 16.04 and rebooting, I cannot get past
the login screen. The screen appears the wrong resolution and squashed
smaller than the screen with a black border. When I login, it accepts
the password, but after a few seconds the screen gets corrupted then
resets back to the login screen.
Rebooting to an older kernel fixed the issue.

4.4.0-72-generic
