Aurosutru, thank you for testing Trusty. Just to confirm, despite the minor false gpu hang, is the originally reported issue still reproducible?

Resetting the display screen to never turn off automatically doesn't help. Unplugging the laptop's monitor and plugging it in again will usually restore normal functioning, but only for a while. This sort of problem occurred the previous two times automatic kernel upgrades were installed and was fixed by a display manager update that followed about a week later, at least in one case. Maybe three times is a charm and the underlying problem will now be solved. Thanks. I'm filing another bug regarding a crash that occurred during one of the video hang-ups when monitor unplugging didn't help.
