matrox 450 problem
 

I am trying to setup a matrox 450 dual head card. running ubuntu breezy badger.
Installed mga 4.3 from matrox site using its install.sh file.
running the same monitor. Also have a nvidia monitor card that came with the dell computer. So I am running the main monitor on it and would like to run another on the matrox 450 card.
I have read all the postings I could find and got X to start but in the var log it says
(EE) Screen 1 deleted because of no matching config section.
(II) UnloadModule: "mga"

Any help would be greatly appreciated...

my xorg.conf file is;
