I'm seeing the same thing with a radeon 8500LE. I can still ssh into the system so I'm attaching some debugging info. If you need anything else, please say so, I can obtain new traces etc when it happens again.
File contains: - X backtrace - X strace - dmesg - /proc/mtrr - lspci -vvv Unfortunately I already killed compiz before performing an strace etc. ** Attachment added: "debugfiles.tar" http://launchpadlibrarian.net/8534201/debugfiles.tar -- random system freeze when desktop-effects activated https://bugs.launchpad.net/bugs/115283 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is a bug contact for compiz in ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
