It's a little better in lucid but not much. I turned off the vsync
option which helps the most, but Xorg is still taking far too much CPU
when the machine is basically idle. I've got a new more powerful laptop
(with an i5) so it's hard to directly compare, but Xorg is constantly
using ~2-3%. kwin uses very little now vsync is off and powertop says
it's waking up much less as well.

kwin uses way too much CPU when there's no activity
