gnome-shell crashed with SIGSEGV in meta_monitor_get_main_output() from meta_monitor_get_vendor() from logical_monitor_has_monitor()

[[e-mail]]

17.10 Beta Fully Updated and re-installed in a fresh partition for best results.

When screen went blank at time out, returning it from "its' hibernation state" screws up "workspace to Dock"

So Alt+F2 and "r" brought it back but other things like terminal stopped working.

Trying to help, Mark
