[i965gm] Xorg crash, randomly since ca. Apr 20

[Timo Jyrinki]

Binary package hint: xorg

Seemingly random crashing, usually quite soon after logging in if it happens. Started recently during the last two weeks, about the same time as unity stopped crashing (which didn't bring X down). Seems to be triggered by _some_ action of mine, usually alt-tabbing or some other application switch / startup event. But it easily doesn't happen during a day more than once.

This happens to me as well. Didn't happen at all the first few days, but has suddenly started happening all the time. Every 15-30 mins. Not sure if it's relevant but I've had no other program besides Chromium running when it's happened.
