Yes it appears your gnome-shell process is crashing with "Connection to xwayland lost".
So this is generally either bug 1505409 or bug 1556601. It's unclear if "intel_do_flush_locked" is related because in the first instance you showed that happening before the crash, and in the second instance it is logged after (with the same timestamp though). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1730184 Title: org.gnome.Shell.desktop[29954]: intel_do_flush_locked failed: Bad address To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1730184/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
