Comment 1 for bug 113815

Thanks for reporting this issue.

This could be tough to figure out without some additional information, though.

Could you run /usr/share/bug/xserver-xorg-core/script and attach the output to this bug report?

Also, could you describe what you're doing prior to it freezing up? any particular software you're running? Does it freeze while you're using it, or after its been inactive for a time?
