Public bug reported:
Platform: Ubuntu/Kubuntu 8.10 on a Macbook 2,1 running KDE 4.2
Symptoms: X server crashes when moving mouse pointer out of fullscreen
RDP session. I have an external 20" display, set with xrandr to be below
the laptop display. To trigger the bug, I connect to a Windows host
using RDP and KRDC 4.2, set the view to fullscreen (1680x1050) and use
the system normally a bit. Then, apparently randomly _but always after a
while_, when I try to move my mouse pointer from the fullscreen RDP
session up to the laptop screen, X server crashes.
Backtrace below:
