Two points here:

1.  Default video mode for laptop cards are sometimes BIOS settable.
2.  Default video mode for every video driver may be different.

For example:

The radeon driver will 'mirror' the video to the external vga adapter.  
In this mode, just plug in the projector and it will be a mirror of the 
screen display.  HOWEVER, any application that uses direct access to the 
video card (such as a video player) will not send it to the projector.

The commercial ati driver fglrx, does NOT mirror the display by 
default.  However, if I use the laptop CRT/LCD buttons to switch to 
external, then start X, it will even do videos.

Steps with fglrx driver:
sudo init 3
close up and head to meeting
plug into projector
hit CRT/LCD button  -- for DELL Latitude D600 is <Fn>F8
I now see my display on the projector
sudo init 5
