Dual head display issues with Warty

The file is attached!

You get pretty used to the fact that you can't drag and drop windows, as
it gives a clear purpose to each screen. When I switched to Ubuntu it
took me a good few hours reading x manuals and configuration files and a
day or so of trial and error before I came up with this configuration.
I've also managed to set up dual monitor so that you can drag and drop
windows from one monitor to the other however in this set up X didn't
allow me to use different resolutions on each monitor.

Currently I'm set up as follows:

Primary LCD Panel on Laptop, 1600x1200 resolution
Secondary LCD Panel connected to VGA connector at 1280x1024.
Secondary Panel on the Left of Primary Panel
Using ATI fglrx drivers. 

The only major issue that I found so far is that if the secondary panel
is disconnected X doesn't start with this configuration, so you need to
manually comment out everything related to the secondary panel and start
X again. I've got a basic script that does that for me using 2 config
files one for dual monitor and one for single monitor. Ideally at
startup I'd like to detect home many screens are connected and use the
appropriate configuration, however I haven't as yet spent enough time
trying to figure out how to do this, any suggestions would be helpful. 

Anyway, hope this is of some help.
