After upgrading mutter (3.24.4-1 -> 3.26.1-1) as packaged with ArchLinux, the following assertion is hit when switching screens on a machine that has only the KVM connected: mutter:ERROR:backends/meta-monitor- manager.c:2267:meta_monitor_manager_get_logical_monitor_from_number: assertion failed: ((unsigned int) number < g_list_length (manager->logical_monitors)) A full excerpt from the systemd journal including a coredump is attached. As a result, my Gnome session dies everytime I switch screens. The assertion is not hit on a laptop (with an internal screen) that is connected to the same KVM. Based on the assertion's text, this seems logical as it likely only hits when the only screen is "unplugged". Thank you for your time on working on OpenSource software!

This bug was reported for Ubuntu Desktop 17.10. I would like to add that the problem when disconnecting the only monitor also occurs when using Ubuntu Desktop 18.04 LTS (latest updates Jul19,2018). gnome-shell will not always crash but the desktop becomes unusable when using x11vnc.
