Comment 11 for bug 438000

I can also confirm that i am receiving these issues on the 9.10 release.
i have dual monitor setup using 1024x768 on laptop monitor and 1280x1024 on external monitor. Enabling compiz causes X lockup and prevents any system use, a reboot is then the only way to unfreeze.
I also had lots of problems with jaunty video output and the 2048 texture limit.

Laptop contains the Intel 945GM card and appears to be a common component in lots of video problems.
