My girlfriend's old Macbook Pro's screen went kaput, and I have it hooked through dvi-d to my external monitor. All that shows up is the starry default wallpaper that Apple has, and not her desktop. (it's acting as a connected 2nd screen, I can drag the mouse off of her laptop's screen and it appears on the external display.) anyway. is there a way to command the macbook pro to use the dvi output as it's main? So we can see her desktop on my external display? What I mean by command is something to do with the keyboard, since we can't see the screen on her actual laptop to go into system settings. I heard command F3 changes display mode but does nothing when I do that. s.o.s. ?
