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).
