You have been subscribed to a public bug: I am using ubuntu 14.04 64-bit. (All my packages were up-to-date as of about 1 week ago.) My hardware is an Acer C720 (Intel graphics). The symptoms of the problem is the display completely stops updating, except the mouse cursor continues to move. Clicking and any keypresses have no effect. The system remains in this state for about 15-60 seconds, then it recovers and goes back to normal.
The problem most commonly happens when using chrome or chromium to do any kind of intesive hardware-accelerated rendering. Typically a youtube video or and HTML5 game with lots of animations. The problem tends to happen during periods of high CPU usage.
