Title:
gnome-shell crashed with SIGSEGV in meta_window_get_monitor()
Status in gnome-shell package in Ubuntu:
New
Bug description:
I can only describe the events leading up to the crash reporter
popping up on my screen.
I have a Intel NUC i5-7260U connected via a HDMI cable to a Samsung
UE46D6515 TV set. I turned off my TV using the remote control and
when I turned it back on, the keyboard and mouse were unresponsive for
a few seconds. Moments later, all was well but the crash reporter
appeared.
I might add that I had difficulties with powering off the TV under
17.10, leading me to switch to X11 (which worked better but had
similar problems).
All the best, Gísli
