Title:
gnome-shell crashed with SIGSEGV in meta_window_get_monitor()
Status in gnome-shell package in Ubuntu:
New
Bug description:
If I switch off my monitor or if it goes to sleep, with either Dash To
Dock or the Ubuntu-flavored version of the plugin will crash and
refuse to work until I reboot.
It doesn't seem to happen on Ubuntu 16.04 with gnome-shell and an
Nvidia graphics card (I tested it with that hardware on another
system), but seems to exhibit this behavior more often on my Intel
integrated graphics.
