This happens to me too, but with Ubuntu 20.04. It started shortly after the latest nvidia-graphics-driver-470 update. Symptoms are:
* graphical output freezes completely * no reaction to any kind of input (no switching to tty either) * ssh works and shows Xorg as using 100% CPU * Xorg process can't be killed * shutdown command is not executed (only ssh connection is terminated) My GPU: GTX970. I've never had this problem before, although my PC is has not been modified for years. Now it happens multiple times per day! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1942271 Title: Spontaneous NVIDIA panic To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-470/+bug/1942271/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
