Public bug reported: Suddenly my laptop's cooler fan began spinning very fast while the system was completely idle, I wan't even using it though I had a few programs opened.
So I ran top, and I saw the Chrome and Firefox processes were alternatively consuming 70% CPU each all the time. There were only static idle pages open, no youtube video, nothing of that kind, no script running. I closed Firefox and Chrome kept consuming 70% cpu, then I closed Chrome and it obviously stopped. It would be a very strange coincidence that it was a bug in both browsers manifesting itself at the very same time, so that's why I'm reporting this against xorg: it's almost surely something at the system level, and I strongly suspect something graphical (perhaps nvidia- related? as the broken nvidia driver's bugs are usually rensponsible of most of Ubuntu's tremendous instability).
