Hi folks -

I routinely use xrandr (through KDE) to resize the X screen on my laptop,
when I dock it or de-dock it.  Every so often, after resizing it down to
1600x1200 (from either 1920x1440 or 2048x1536) my mouse pointer vanishes.
KDE still sort-of responds to a moving mouse because the panel at the bottom
of the screen appears when I move the mouse (or the imaginary one) down.

But, I can't get any of the windows into focus.  Nor can I click on
anything.  Nor do I have any sort of keyboard input other than
CTRL-ALT-BACKSPACE.  Once I restart the server, all is well.

Is there any set of logs or diags I can get for you guys the next time it
happens?  I can't reproduce it at will, but I figure it'll happen again
within the next few days.

Hardware: IBM Thinkpad T42p with ATI FireGL T2
Software: Fedora Core 3 / Xorg 6.8.1.

The xorg.conf follows, if it's at all interesting:
