I also have this problem (using a laptop with an Intel GMA 945 graphics controller). I can confirm that no crash happens with the following sequence:
Boot laptop with external monitor unplugged,
Disable visual effects,
Plug in the monitor,
Type "xrandr --auto" in Terminal,
Go to Display Prefs,
Turn laptop monitor off,
Keep external monitor on/Set external monitor to max resolution,
Fini!
Now how can I get the external monitor plugged in without having to go through this process?
