Public bug reported:
Latest liveCD of ubuntu-gnome is maxing out the CPU. "top" shows gnome-
shell as the culprit.
The system is very sluggish. Trying to do anything is like the
proverbial wading through treacle.
At least it has improved since the last kernel upgrade. Before that,
gnome-shell was crashing.
The graphics chip is a bit old (and an oddball one). I tried loading the
vesa driver to see if that made any difference. It doesn't.
