Can I force Linux to rescan for monitor changes at boot


I have a small IT shop and one thing we are interested in doing is offering Ubuntu or Debian on the refurbs. To save time I installed a monolithic kernel (with all driver support) and booted into it. When I took the drive out and put it on another machine it worked. The OS ran and worked fine. I figured this would work since Linux is available as a Live CD. The only problem was that xorg.conf wasn't regenerated and Linux couldn't load the GUI. This is very common and happens whenever I change monitors. This is usually a pain to fix. What I was wondering is if there's a way I can force on boot up to redetect the monitor, video card, etc. like a live CD. Any help?

You might be able to use udev. Here is a page that describes how to manage devices based on device characteristics such as manufacturer, model, etc. We know that the Linux system is capable of querying monitors and finding their resolution.

The parent page is amazing in the amount of different areas that are covered in this "how to" site. Much of the information can be applied to any distribution.
