This bug happens to me quite frequently (from once to three times per day) and it's quite annoying.
It appears to be random even if sometimes it happens when I try to open the notification window (in the topbar clicking on the date time) -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1705492 Title: gnome-shell crashes with SIGSEGV in meta_plugin_manager_xevent_filter() from x_event_source_dispatch() Status in gnome-shell package in Ubuntu: Confirmed Bug description: I can login using unity but when I choose gnome it takes while and the screen turns black and eventually it brings me back to the login page. this only started happening after upgrading to ubuntu 17.10.
