bump... Anyone else have any luck with clam shell mode?
Well, what I usually do is keep my lid open, cuz if I close it, then it sleeps--but it works just like it was closed.
I have a macbook core 2 duo--with the GMA 950--the intel one you've got. Anyways, right click desktop, go to graphics options, output to, digital display (or analog display) and that will directly output to your external display. You can also do extended desktop.
Just right click the desktop, then go to graphics properties. You can set it to display to both your display AND your macbook then--you can even change the resolution of both using some of the other tabs. just look for it.
Hope that helps!
