I found a realy good solution for my Bug, so you may look if this helps you too.
https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics- drivers-180/+bug/353502 So i found out that for me installing the newest nvidia-driver solved a lot of my Problems since then i do not have any freezes. I am working with all off my 4 cores now, i have enabled Compiz, I am able to show Videos. Even my Sound-Driver does Work now relaiably. (ever once in a while it worked after a new boot, most time there was even no chip found) In the last Month i did try these drivers several times, but without success. But now i tried them again because i read about it in bug 353502 So if you happen to have nvidia-graphics, try it out Andreas Kielkopf -- Clocksource tsc unstable leads to lockups in Ubuntu Jaunty https://bugs.launchpad.net/bugs/355155 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
