@ Geoff Smith (taurusone) this is another, very similar bug, in your case "only" X (graphic environment) freezes. in other cases, the entire system freezes, no response from mouse or keyboard...
i have entire system freezes in KDE (kwin), Unity (Compiz), Gnome (Mutter). unity-2d works fine... probable all desktops without 3D effects... perhaps a bug in 3D driver mesa? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/993187 Title: ubuntu 12.04 64bit completely freezes frequently To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/993187/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
