I just upgraded to Ubuntu 18.04 with libmutter 3.28.0-2 and ran into this; monitor poweroff/poweron yields a crash of gnome-shell. The good news is that the applications are not killed like they were in 17.10 (with wayland?). But waiting for the ubuntu-bug crash file to get generated isn't a good use of my time either.
For me, applying the following patch works: https://bug788834.bugzilla- attachments.gnome.org/attachment.cgi?id=361331 Patched binaries are here: https://downloads.osso.nl/libmutter-3.28.0-ubuntu- bionic/mutter_3.28.0-2osso1/ Cheers, Walter Doekes OSSO B.V. -- 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/1724439 Title: gnome-shell crashed with SIGSEGV in meta_window_get_monitor() from ffi_call_unix64() from ffi_call() from gjs_invoke_c_function() from function_call() To manage notifications about this bug go to: https://bugs.launchpad.net/mutter/+bug/1724439/+subscriptions -- desktop-bugs mailing list firstname.lastname@example.org https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
