In Section "Screen", the DefaultDepth item sets which SubSection 
"Display" is used, i.e. if DefaultDepth 24, then the "Display" section 
that has Depth 24 will be used.

I hope that's right. I figured it out by trial and error. Man pages are 
helpful but I always find I need to do trial and error guesswork to 
figure stuff out. Man pages just kinda give me clues to work with :-).

Resolution defaults to the highest resolution that xorg can actually get 
to work from within above mentioned (designated by DefaultDepth #) 
"Display" SubSection, I think.
