what do you do to enable the external monitor?
When it is black like that but you can still move your mouse it is a compiz+dualscreen set up. You can only have a virtual desktop size of 2048x2048 max with compiz. When it enables the external monitor and does so with over 1024x#### then you get this problem with compiz (cuz your netbook is already 1024x600).
What sort of monitor do you have?
Try disabling compiz, connecting and enabling the external, open a terminal and run the command:

xrandr -q
and post the output here, but also answer my other questions please.

I want to know how you detect the monitor which sets up the dualscreen environment with the black screens with moveable mouse. The method.
xrandr manually?
System -> Preferences -> Display?

Also, is it the Acer X233H 23" monitor?
Cuz if it is... wow are you in luck haha. I just wrote a 522 line script for my girlfriend to get that working properly and sexily with muliple configuration options. She uses a Dell Mini 10v and I use an Acer Aspire One which are both netbooks.

So, when you get a chance, answer these questions and the others etc and I will see what I can do to help you out.
