[Daniel Knittl-Frank <492782@xxxxxxxxxxxxxxxxxx>]

this has been happening to me for about a week now running fully
upgraded natty with nouveau driver. graphic card is 01:00.0 VGA
compatible controller [0300]: nVidia Corporation G86M [Quadro FX 360M]
[10de:042d] (rev a1)

after some time the mouse cursor will randomly disappear on my external
monitor, with no errors in Xorg.0.log (but errors in kern.log)

other times the cursor is still visible, but if the cursor changes shape
(textcursor, loading, links) it will be verry sluggy for a moment
(pulseaudio also hangs while this) and trash kern.log with "no space
while unhiding cursor" messages. when the symptom is a disappearing
cursor only the "EvoCh" line is written to the log file, i.e.

    Feb  7 10:28:05 kbook kernel: [49943.295050] [drm] nouveau 0000:01:00.0: EvoCh 0 Mthd 0x0000 Data 0x00000400 (0x0002 0x01)
    Feb  7 10:33:01 kbook kernel: [50239.740629] [drm] nouveau 0000:01:00.0: no space while unhiding cursor
    Feb  7 10:33:01 kbook kernel: [50239.871880] [drm] nouveau 0000:01:00.0: no space while unhiding cursor
    ...

starting the monitor resolution tool will completely freeze X, logging
out will not restart X, killing X with ctrl-alt-backspace will hang the
screen. the only thing to bring the mouse cursor back to a usable state
is to restart the machine (either using shut down from the gnome panel,
or after X has hung up using sysrq-reisub)

i'll be glad to provide further log files or system information. this
bug is really annoying.
