Dear all,
I'm using kubuntu karmic with old nvidia graphics. I was fighting with 100% CPU usage in xorg very often. I had to install lxde as an alternative to kde, to be able to use my computer at all.

Few days ago I have finally found my problem - the CPU hungry task was ica. I don't know why this task is running by default in ubuntu, but killing it always solves the problem, CPU usage drops below 2%.

the command is:
sudo killall ica

I hope this can help to others,
Jan
