xserver jammed up (only mouse working)

[Wookey]

Binary package hint: xorg

I was doing very typical work (for a minute or so after 50mins away) when the machine stopped responding. The mouse moved but keyboard LEDs dead and no screen action. Not even ctrl-alt-F1 or -backspace did anything.

htop told me that the Xserver was running at about 70%, and /var/log/Xorg.0.log said: "[mi] EQ overflowing. The server is probably stuck in an infinite loop. " which seems about right.

I upgraded to Maverick and noveau instead of Karmic and nvidia a couple of weeks ago, so I suspect the noveau driver.

Hey Wookey,

Hi, have you had a chance to test if this bug is still present in natty?

If it does (and if you're the original reporter), please boot into natty
and run the command:

  apport-collect <bug-number>

which will update the bug with fresh logs and tag the bug as affecting
natty. (It is best to run this right after reproducing the problem.)

[bugbot (bugbot)]

We're closing this bug since it is has been some time with no response from the original reporter. However, if the issue still exists please feel free to reopen with the requested information. Also, if you could, please test against the latest development version of Ubuntu, since this confirms the bug is one we may be able to pass upstream for help.

Problem finally went away with upgrade to Oneiric.
