Kind of the same problem, think it has been reporter in xorg's bug tracker as well (I just do not find the reference right now but there are similar bugs).
I think it happens less frequently when using the ati driver instead of the fglrx driver, but I do not guaranty a fail saif. It has nothing to do (by me) with Beryl/Compiz or XGL. Someone on Xorg's bug tracker emitted the possibility for it to be a memory leak than can possibly occur with any driver, but that where some kind of speeded up using some particular drivers or doing particular things (intensive windows resizing has been reported to be likely to help the bug to occurs). I tried upgrading xorg to the gutsy's one, the I have a bug that prevent me from using the 3D in fglrx, but I seem to have much more frequent freezes with ati's proprietary driver (just for the 2D part) than with the free xorg driver "ati". When freeze occurs, cpu raise to 100% (both cores), if I have the time, I can stop the freeze by killing xorg (one to five seconds to understand that there's going to be a freeze and react). The mouse is still alive, but I'm not able to switch to another terminal. Some tells that it i possible to connect to the host via ssh and kill xorg to get out of the freeze. -- ubuntu randomly freezes https://bugs.launchpad.net/bugs/117651 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
