Freeze observed with both nvidia-glx : 1:96.43.05+2.6.24.12-16.34 nvidia-glx-new 169.12+2.6.24.12-16.34 -- [hardy] nvidia + compiz + xorg freezes for a few minutes https://bugs.launchpad.net/bugs/218743 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
