I have now reproduced the original issue twice: Settings schema 'org.gnome.mutter.wayland' does not contain a key named 'xwayland-allow-byte-swapped-clients'
What happened was that gnome-shell 42.9 got SIGKILL'd (along with all other user processes). And after that the system tries to restart it as gnome-shell 46.0 which isn't fully installed/configured. The SIGKILL seems to have come from a systemd restart. I did say yes to automatically restarting services, so maybe I shouldn't have? may 16 16:17:07 jammytest2 systemd[1]: Reexecuting. ... may 16 16:17:09 jammytest2 systemd[1]: user@1000.service: Killing process 1228 (gnome-shell) with signal SIGKILL. ** Attachment added: "journal.txt" https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/2054761/+attachment/5778984/+files/journal.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2054761 Title: gnome-shell crashed with signal 5: Settings schema 'org.gnome.mutter.wayland' does not contain a key named 'xwayland- allow-byte-swapped-clients' To manage notifications about this bug go to: https://bugs.launchpad.net/mutter/+bug/2054761/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
