EeePC with an external monitor

Triumph! For the longest time, I wondered why X would never honor my DPI settings, even if i passed it the -dpi 96 command line flag. My fonts would look fine using the EeePC screen but look too small on my external monitor (or if I fiddle with my xorg.conf it'd be the other way around). It turns out I have to add sections for each monitor and name the identifiers something special to normalize that DPI:

Section "Monitor"
  Identifier  "LVDS"
  Option    "DPMS"
  DisplaySize 270 158 # 1024x600 @ 96dpi
EndSection

Section "Monitor"
  Identifier "VGA"
  Option    "DPMS"
  DisplaySize 488 304 # 1920x1200 @ 96dpi
EndSection
