Good point Dave,

Many laptops have to be told in BIOS to do "dual"  monitors or there's a 
keyboard combination that enables the additional output.  Usually that 
key combo cycles through turning off the internal monitor and turning on 
the external, then to dual-mode, then back to internal only. 

What type of video card is it?  Some of the more modern laptops treat 
the external port as a completely separate desktop and you have to set 
up X to drive both.  (Rare-er than the first but starting to become 
popular.)
