It may be the Arc shell theme, in interaction with nVidia: I was unable to reproduce the problem on the Macbook Pro using Xorg gnome session, and that still with the Arc shell theme. Both a short (few minutes) and long (greater than one hour) display sleeps tested.
I was also unable to reproduce it on the nVidia-equipped desktop with the Default shell theme selected, on either short or long display sleep. needs-root-rights is still set to yes in this configuration (ie: the same as tested yesterday evening except for switching back to default themes.) I don't know how a theme can cause a segfault, it's just image assets and css. But I'll leave it on Default for now to see if the issue does after all recur. I'll also go back to modeset=1 but needs-root-rights left unset, and wait and see. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1720149 Title: gnome-shell segv on wake from display or system sleep To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1720149/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
