Yes this looks like a nouveau kernel driver bug. I recommend using the proprietary Nvidia driver instead, but it seems your GPU only supports driver version 340 and that's now too old to be supported in Ubuntu 21.10.
So to continue using the "nvidia quadro nvs 290" you should probably install Ubuntu 20.04 instead where it is still supported. ** Package changed: gnome-shell (Ubuntu) => linux (Ubuntu) ** Summary changed: - ubuntu desktop - changing display configuration lost wallpaper (trap messages filled dmesg) + [nouveau] ubuntu desktop - changing display configuration lost wallpaper (trap messages filled dmesg) -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1930945 Title: [nouveau] ubuntu desktop - changing display configuration lost wallpaper (trap messages filled dmesg) Status in linux package in Ubuntu: New Bug description: Ubuntu Desktop Impish daily test on - hp dc7700 (c2d-e6320, 5gb, nvidia quadro nvs 290) Changing display positions in settings. I have two monitors, one above the other (so not the default). I made change and it looked okay so I said keep.
