Public bug reported:
Binary package hint: xorg
I recently updated to Gutsy on my HP Compaq TC4200.
It's a tablet that uses mostly Intel hardware, a Broadcom wired ethernet
(it works), and a Texas Instruments card reader, for what it's worth.
When I come back to it after I've closed the lid (Under Power Management
Preferences I have it set to "When laptop lid is closed: Blank screen",
the default), the poor thing becomes possessed:
* The cursor jumps around insanely when I move the mouse.
* Everything becomes painfully sluggish and unusable.
* Sometimes windows I'm working with go dark and unresponsive (Compiz effect,
though I have this same issue if I turn off desktop effects, so it's probably
not Compiz related)
* top shows that Xorg is hogging up between 40% and 70% of CPU cycles.
* I can't get a Ctrl-Alt-F1-F6 consoles to come up (They flash onscreen for a
split second and then the screen goes black, sometimes with a white arrow
cursor frozen on it somewhere...).
* When I do a Ctrl-Alt-Backspace to reset the X server, I notice the
characters "^@" start appearing across the screen.
* A Ctrl-Alt-Backspace doesn't fix the problem.
* Sometimes the X server resets itself with no outside influence (behaves like
I'd hit Ctrl-Alt-Backspace)
* Sometimes/eventually the laptop becomes completely unresponsive.
I only recently figured out that the problem seemed to happen after I
closed the lid and opened it back up.
I'm going to try switching my "When laptop lid is closed:" option to "Do
nothing" to see if that helps me avoid this crippling and seemingly
random (before I figured out that it might be related to the lid
closing) possession.
