Title:
gnome-shell crashed with SIGSEGV in meta_window_get_monitor()
Status in gnome-shell package in Ubuntu:
Confirmed
Bug description:
On Ubuntu 17.10. when disconnecting the display cable (HDMI), or
changing the input on my HDMI splitter, the desktop on my pc crashes.
It looks like you're getting logged out and have to newly log in (all
programs get closed).
I can 100% replicate this on my computers. One is using the nVidia
proprietary, and one the AMD opensource driver (r900).
This behavior was not present on any previous Ubuntu versions.
