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.]
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”. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/767102 Title: [arrandale] GPU lockup (ESR: 0x00000001 IPEHR: 0x08000020) _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
