Logged into Gnome-Shell as Guest user, same problem. I was pretty much just using firefox. It locked up, mouse would move, nothing would respond.
I'll continue to see if I can find a culprit. Attached was the output of top -b -n 1, dmesg, and ps aux. This has been frustrating and the worst experience with Ubuntu to date. I wish I could figure out what the problem is. ** Attachment added: "top dmesg and ps" https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers/+bug/976383/+attachment/3049331/+files/debug.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/976383 Title: Periodic lockups or crashes To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers/+bug/976383/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
