I have similar problems with a Dell Latitude D610 w. Intel 915GM. After booting without the external screen connected, trying to switch to the external screen gives the result that both screens are black, and then it's impossible to restore to the laptop screen without restarting X. The external screen seems to get some kind of signal that it can't synchronize to. Switching to the external screen w. Fn-F8 early in the bootup process works, and gives a working X environment. This is written in Xorg.log when I press Fn-F8 the first time: (WW) I810(0): Detected possible lid operation, fixing up. (II) I810(0): Display plane A is disabled and connected to Pipe A.
