[H-GEN] Firefox Fullscreen Spanned over Multiple Monitors - Please Help

[cornernote]

Hello,

I have got dual spanned monitors working under Ubuntu 5.10 using this
xorg.conf file:
  http://mg.pov.lt/xorg.conf

My next issue is getting Firefox to span in fullscreen mode across the 2
screens.  It works perfectly in windows using this extension with a slight
change:
  https://addons.mozilla.org/firefox/1659/

The change is in rkioskbrowser.js under:
  BrowserFullScreen();

Add:
  window.resizeTo(2048,768);
  window.moveTo(0,0);

However it appears that in Linux X, I cannot do anything to the Firefox
window once it has been fullscreened.

My next effort is to modify xorg.conf to force every window that is
fullscreened to take up both monitors.  This should solve my problem.  I am
looking for any assistance in this area as last night was the first time I
have ever seen an xorg.conf file and I am still getting familiar with all of
the settings and their effects.

If anyone can tell me how to modify the file to get the required results
then I would be very grateful.


Best regards,
Brett
