I think that I found solution for this problem. In that site: http://fedoraproject.org/wiki/Xorg/Debugging
"Some issues may be worked around by disabling kernel mode setting. To do this, add nomodeset as a kernel parameter." I did so, and was able to change appearance preferences visual effects to normal and extra. Compiz effects working fine too. Someone with this problem, please confirm my solution. -- Xorg freeze without reason in Ubuntu 10.10 https://bugs.launchpad.net/bugs/658649 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
