It is possible to have two serverlayouts, he just needs to define which
one is default with a statement like this Option "DefaultServerLayout"
in the serverlayout. Then later if he wants he can tell XFree to start
the single head with the -layout option.

Anyways, that's not why I am writing. I am also having troubles with
dual head setup, but on a Radeon 7500 desktop card.

My /etc/X11/XF86Config-4 file is as follows:

--------------------
 

I don't get any error messages in my /var/log/XFree86.0.log file and
the log file even shows the layout like this: 

Code:
--------------------
    
  (==) ServerLayout "Default Layout"
  (**) |-->Screen "Right" (0)
  (**) |   |-->Monitor "DELL P793 Right"
  (**) |   |-->Device "Radeon 7500"
  (**) |-->Screen "Left" (1)
  (**) |   |-->Monitor "DELL P793 Left"
  (**) |   |-->Device "Radeon 7500"
  (**) |-->Input Device "Generic Keyboard"
  
--------------------


But I still get mirrored displays. I have had dual head running on this
computer with both XFree86 and XOrg on other distros (Gentoo) and I had
saved copies of those XF86Config files and simply modified my Ubunto
one. Can you, or anyone else, see where I've gone wrong?

Thanks for any help

-Sam
