My experience is that when I plug in the projector while X is already running it loses sync..basically a black screen...
But when I start X while connected to the projector it displays fine (1024x768).. This is a HP pavilion ze4900 (with i810 video card)...
it can get worst than that. In a few cases (mostly Compaq), if you don't have the projector connected before you turn the notebook on, you don't even get the text boot sequence to show. Using the function keys on the keyboard you get the feeling that the SVGA port is being activated (the LCD screen blanks etc etc), but you still get no image.
Way out: 1. Connect the projector 2. Switch to console with Alt+Ctl+F1 (or F2...) 3. Toggle to projector setting (or shared setting) As you are in text the projector will beam the command line. 4. Start another X session by command startx -- :1
This works for me almost always subject to X resolution being within power of projector. By experience mostly 1024x768 works.
