The relevant sections are reproduced below. My setup is slightly unusual,
because my external monitor runs at a very high resolution. It satisfies the
following constraints:

 * If I start X without external monitor, I get 1024x768 on the laptop panel.

 * If I start X with my monitor connected, I get a desktop which is
   1920x1200. The entire desktop is visible on the external display, while the
   laptop panel is a 1024x768 viewport into the desktop, which I can scroll
   with the mouse (usually I just turn the panel backlight off, and look at
   the big screen).
 
The main reason I set it up like this is so that I don't need to change config
files or serverlayouts when I go mobile. If I really want a desktop which is
1024x768, I just unplug the external and restart the X server.

The one bug I have with this setup is that the DPMS causes the laptop panel
backlight to turn on. I have not looked into this, instead I just put a cover
on the screen when I'm trying to sleep. :)
