Configuring Xorg to be Intelligent.

[Scott Ryan]

I am trying to configure Xorg for two setups. Currently I have to manually 
change between when my laptop is in the docking station and when it is  out 
of it. In the docking station my monitor supports 2048x1535 @ 75Hz, and when 
it is out of it, it only supports 1400x1050 @ 60Hz. Is there I way I can 
configure Xorg to intelligently detect which config file to use, or is there 
a way of putting both configurations in the same config file?

Many thanks
