Bug Description
Reported initially as comments of bug #1887998:
[ Impact ]
Ubuntu session doesn't start with some particular monitor configurations, as per this fatal assertion:

Jul 27 00:30:33 jojda gnome-shell[15068]: Bail out! mutter:
Jul 27 00:30:33 jojda systemd[4297]: gnome-shell-
Jul 27 00:30:33 jojda systemd[4297]: gnome-shell-
[ Test case ]
Start ubuntu session, you should be able to log-in and no error fallback dialog is shown.
[ Regression potential ]
Screen size is not set properly for the session, panning is enabled.

Symptom is that after waking up from sleep I get white screen of death that says what the bug description says ("Oh no! Something has gone wrong. A problem has occurred and the system can't recover. Please log out and try again.") and I have to click the Log out button at which points it lets me log in again. Sometime it does the same thing again right after logging in.
Syslog message are also pretty much the same as from other comments, here you can see it failing twice, first up while running then right after re-login.
