As an attempt to remedy the problem I installed and enabled the restricted ATI driver "xorg-driver-fgrlx" and corresponding "xserver- xgl" via synaptic. After reboot I did not experience any freezes, but saw that rotating the cube suddenly consumed more processing time than before (I guess it must use sw rather than hw to render). So I decided to revert back to the open-source driver (uninstalling both packages) and I have not seen any freezes yet. I have slowly enabled various plugins (not the animations yet though) and are still not experiencing freezes.
I'll keep testing and trying different configurations and return with more info :-) -- X freezes when compiz is enabled on ATI cards https://bugs.launchpad.net/bugs/108527 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
