Problem NOT using Xinerama with Quadhead

[Markus Manninger, Ing.]

Hi,

I made my quadhead system running but just with the option "Xinerama" 
"on" ... if i change it to of the xserver hangs after starting. If i use 
the xinerama everyting runs well but i need to access the different 
displays.

Here is my xorg.conf:

Maybe someone can help me how to turn off the xinerama feature?

Thanks,
Max
