Just for the record, I see the same issue with a Dell Precision 7760 (CID 202103-28858) when running 22.04 beta on Wayland. I was told the HDMI connector was wired directly to the Nvidia GPU, so gnome-shell crashes when I connect an external monitor there, but even after logging back in, the monitor cannot be used.
Plugging the same monitor to the USB-C connector (which is wired to Intel GPU apparently) works like a charm... -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/1964037 Title: gnome-shell crashes (fatal error logged in create_fallback_offscreen) when attempting to enable second monitor on second GPU (Nvidia >= 495) in a Wayland session Status in Mutter: Unknown Status in OEM Priority Project: Confirmed Status in mutter package in Ubuntu: Fix Committed Bug description: This is on my weird desktop setup, with one monitor plugged into an AMD card and one into an NVIDIA card. When using the Wayland session, by default Shell will come up on the monitor connected to the AMD card, and the second (NVIDIA) monitor will be blank. Attempting to enable the second monitor in Display Settings will immediately and reproducibly crash gnome-shell. This is trivial for me to reproduce, so if you need patches tested I can easily do so.
