Ah thanks, you mentioned you were due to reboot; was that because you'd just done a system upgrade? I wonder if that could have triggered the freeze.
But yeah, generally once your GPU has locked up, it's game over for the GUI; only very rarely can you get X let alone compiz to work again after that; a full reboot is almost always required. ** Summary changed: - [arrandale] GPU lockup (ESR: 0x00000001 IPEHR: 0x08000020) + [arrandale] One time GPU lockup (ESR: 0x00000001 IPEHR: 0x08000020) ** Description changed: - Binary package hint: xserver-xorg-video-intel + It was the first time for this sort of failure, but it actually wasn't a + system freeze: I could switch to virtual consoles and back, but no + amount of trying to restart unity would work; each time compiz would + crash. I was left with no ability to type in X, and no window + management. Hence the lack of comment in the original description: the + best I could do to satisfy Launchpad's demand for a description was to + copy and paste the pre-filled summary with my touchpad. I did resort to + restarting my system after that, as it was due for a restart according + to update-manager. [And then it was late so I went to bed and forgot to + follow up on this bug to explain in more detail.] - [arrandale] GPU lockup (ESR: 0x00000001 IPEHR: 0x08000020) + I don't recall any failures like this one on maverick. I got freezes + only very rarely on maverick, but did sometimes get *extremely* slow X, + where input would take many seconds to have any effect (and IIRC CPU + spinning at 100%). IIRC that was triggered by switching between + different X sessions (e.g. between the guest login and my login).. + + On reproducing: so far it's just happened once, for no obvious reason, + so I'd have to say “randomly”.
