To be sincere, nowadays that X in "dinamically" setup, I'm not sure.

I had previous experiences with xorg configuration that couldn't properly
detect the display resolution but just by forcing it (writing up in 
xorg.conf file) it just worked :-?

Also, using a digital output -DVI instead VGA- (if available) can help X 
to detect the screen size and adjust it accordingly.

Another thing to look into is the driver in use. Different drivers 
deliver different results. Yes, I know that not everyone likes using 
closed drivers but is just another option to test.
