Like the similar upstream bug https://gitlab.gnome.org/GNOME/mutter/-/issues/1475, this appears to be caused by the intersection of:
(a) GTK being used in the gnome-shell process (usually by extensions); and (b) The absence of an Xserver for GTK to connect to (Xwayland is only started on-demand now). It looks like one possible offender using GTK is gnome-shell-extension- appindicator. I'm not sure about the other extensions, and it's hard to tell with desktop-icons-ng which in theory uses GTK in a safe way (in a separate client process). -- 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/1949200 Title: gnome-shell crashed with SIGTRAP from error "Can't create a GtkStyleContext without a display connection" in gtk_style_context_init To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1949200/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
