Public bug reported:

Binary package hint: xorg

I am running Kubuntu Lucid.  On first booting, everything is fine, but
over time the performance degrades and after about three hours the
system need rebooting.

This is on a 4-core, 4GB RAM with NVidia graphics running the closed-
source nvidia driver.

Turning off compositing makes no difference.  "top" shows Xorg eating
CPU.
