I am seeing the same errors on Intrepid with standard updating (not bleeding-edge) and a Nvidia video card. Running Nvidia drivers and compiz. I'm seeing hard lock ups on X. Have three so far today and never saw this happening before today.
Xorg.0.log reports these errors before the hard lockup requiring a hard reboot: [mi] EQ overflowing. The server is probably stuck in an infinite loop. [mi] mieqEnequeue: out-of-order valuator event; dropping. -- Xorg hangs due to EQ overflowing https://bugs.launchpad.net/bugs/276518 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
