It looks rather like some deadlock or starvation issue. The UI and all userland applications freeze, but events like screen dimming still happen on schedule as I mentioned above. While the screen (jerkily, slowly) dims, I can actually move the mouse and do stuff; once the screen is dimmed it all freezes solid again. Events like turning off the screen when I close the lid, and turning it on when I open it still happen as well.
Occasionally the machine will actually recover if I wait long enough. Usually, however, it doesn't - or it perhaps would if I waited arbitrarily long, but I do have work I want to do. Anything I can do to help find the cause more precisely? -- Hardy kernel causes overheating https://bugs.launchpad.net/bugs/223081 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
