Thanks for the extra information. Does it always freeze the system completely? I understood "games crash X" as if X was crashing, in which case some information can end up in the X server log. In the case of total system freeze it is often difficult to find any information at all.
There are some information on debugging such problems on https://wiki.ubuntu.com/DebuggingXorg and https://wiki.ubuntu.com/Bugs/AtiDriver ** Changed in: xserver-xorg-video-ati (Ubuntu) Assignee: Tormod Volden (tormodvolden) => (unassigned) Status: Incomplete => Confirmed ** Summary changed: - games crash X or freeze system if compiz is turned on + [rv350] games crash X or freeze system if compiz is turned on -- [rv350] games crash X or freeze system if compiz is turned on https://bugs.launchpad.net/bugs/153857 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
