journalctl -b-1 > prevboot.txt and attach the resulting text file here. ** Summary changed: - Xorg freeze + System freezes on resume from sleep -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1915322 Title: System freezes on resume from sleep To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-460/+bug/1915322/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
