Are you trying to tell me that your eee, unlike every one I've ever seen, 
doesn't have a display in its lid?

It doesn't matter how many VGA or DVI ports you have, the internal screen is 
one display, and external (VGA or DVI) ports are additional.  You _can_ 
disable either one - most modern PCs disable the external as soon as you 
unplug it, but the _internal_ screen needs either hardware or software 
control, and it's entirely possible that your old configuration either (a) 
couldn't handle multiple displays, so it automatically disabled the internal 
when an external display was connected, or (b) you used to use a function-
key sequence to switch displays which your current setup isn't recognizing.
