The problem is still occuring. I've been trying to narrow down the problem.
I switched to the command line (Ctrl-F1) immediately after reaching the login screen, killed X, lightdm and unity-greeter and the system still crashes after a while. I can't determine whether the error showing up is the same is in the screenshot in comment #16, since I can only see the top part and then the screen has already frozen. The part I can see reads: BUG: Unable to handle kernel null pointer dereference at (null) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1173581 Title: Ubuntu 13.04 full system crash/kernel panic To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1173581/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
