I just checked with 2.6.31-20-generic, and the problem still occurs with i945gme. (Test run on an HP Mini 110.) Same description: with Compiz on, as soon as I click "Detect Monitors" in the Display Preferences, the screen goes black with the cursor split between the two screens. Reboot is the only way out.
I still have to start Metacity temporarily when I connect the monitor or run the xrandr command directly to place the external monitor logically below the netbook's display.
