Bug description:
I have some daisy-chained DisplayPort monitors connected via a
DisplayPort KVM switch. This crash occurs at the moment the switch is
switched "away" from host 1 to another host. Upon switching back to
host 1, the gnome-session & gui processes have exited and the login
screen is displayed. Makes it difficult to get much work done.
