Public bug reported:
Binary package hint: xorg
I'm running Ubuntu Natty Narwhal beta and Xorg is using from 20 to 90
percent CPU.
I ran top:
gamerchick02@Sidle:~$ top
top - 10:30:10 up 8 min, 2 users, load average: 0.67, 1.54, 1.10
Tasks: 204 total, 4 running, 198 sleeping, 0 stopped, 2 zombie
Cpu(s): 44.7%us, 1.8%sy, 2.5%ni, 50.8%id, 0.0%wa, 0.0%hi, 0.2%si, 0.0%st

This results in sluggishness, high fan use, and general frustration.
Sometimes it's cured by restarting (sometimes up to 3 times) other times
it happens after a reboot. Sometimes it doesn't manifest itself until
after Ubuntu's been running for a few minutes.
Sorry for being vague, but this is not easy to pin down.
