Title:
Gnome Shell crashes with SIGSEGV when I turn off the monitor
Status in gnome-shell package in Ubuntu:
Incomplete
Bug description:
For quite some time, I have seen my gnome-shell session randomly dying
on me when I am away from the desktop for quite some time. Only now
have I found the reproducable cause: when my monitor is turned off (by
power preserving or by pressing the power button), Shell SISSEGVs out
of existance. I guess it is highly related to my destop configuration:
I use proprietary NVIDIA drivers and my display is connected via
DisplayPort, if this gives you ideas. Maybe in the end the bug is in
the driver?
Here are some system logs around the time of a crash, maybe it can
give you ideas what to check or whom to blame. If you need any other
information, don't hesitate asking me for it, I will try my best.
