I just got a Dell Optiplex 755 with a twinhead X1300 card running Ubuntu Hardy
with the latest fglrx drivers from ATIs website, and have encountered what
looks like the same problem.

Apparently these bugs are the same:

However in my case the only work around that works is to disable dri.

Option "ForceMonitors" "nocv" -- same problem.

aticonfig --dtop=horizontal -- same problem.

Symptoms: The mouse pointer is corrupt, and then the computer hangs (requiring
cold reboot) or reboots.

Question: What does the Option "ForceMonitors" "nocv" option do? I tried looking for reference documentation on the options but couldnt.
