Getting bogged down in nouveau kernel bugs probably isn't helpful to testing 21.10. We know nouveau has frequent bugs and that we can't fix them, unless they're already fixed in drm-tip per comment #10.
If you would like to test 21.10 then I recommend changing the graphics card to one that is supported by current Nvidia proprietary drivers. If you would like to just use the machine as-is then I would recommend staying on Ubuntu 20.04 which has a supported version of the Nvidia-340 driver for this card (providing you stick to kernel 5.4?). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1930945 Title: [nouveau] ubuntu desktop - changing display configuration lost wallpaper (trap messages filled dmesg) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1930945/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
