I think I have a very related (or the same) error (or multiple errors). A lot of logs here: https://askubuntu.com/questions/1236721/desktop-hung-up-freeze-gpuwatchdog-segfault-nvidia-frontend-close
(Not sure if they are all the same cause, or different... I think they are the same.) When you search the Internet for "NVRM: Xid 31" errors, you will find quite a lot of results, also a lot of recent results. In my (most recent) case, I have Nvidia driver 450.80.02, and Linux kernel 5.4.0-59. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1852002 Title: Desktop frozen for 30 seconds after Nvidia driver crash To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-435/+bug/1852002/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
