Comment 15 for bug 13597

I orginally reported this bug as a result of high CPU usage by xorg in Gnome
which is slowing down the system overall (INCLUDING high end machines with
plenty of memory) and was suggested to remove powernowd but this did not cure
anything.

Different distro's have quicker Gnome compared to Ubuntu, and it is a growing
problem - http://ubuntuforums.org/showthread.php?t=18197&page=7&pp=10 - many
people are noticing the excessive slowdown and it seem not to affect just nvidia
but ATI owners as well. Some have switched to other distro's such as Fedora and
some are swtiching to use Kubutnu instead as well instead of the default Gnome.

Since it's not a Nvidia problem (there are some with ATI's) it's a problem with
Gnome and the fact that the CPU is doing the work NOT the video card itself.
People are noticing the problem more and more. However this bug have now ended
up as a powernowd issue instead of being about Gnome performance itself.

Most of those people, including myself have used the DEFAULT method of
installing/upgrading to Hoary Hedgehog, nothing fancy, which mean all newcomers
to Ubuntu are going to face this problem too.
