If you've recently upgraded to a 2.6.x kernel, that could be the source of the problem. The new scheduler doesn't seem to play nicely with X running at a nice value of -10. So, re-nice X to 0, and see if that fixes your problem. Search the archives for a method to change the nice value permanently. Note that for me, re-nicing without restarting X didn't work, because not all processes showed up in top, and thus I didn't re-nice them.
