I think the problem is section monitor:

Section "Monitor"
 Identifier "Standardbildschirm"
 Option "DPMS"
EndSection

There is not a refresh info. Do you have a ATI pannel installed into your O.S. ???
Which motinor resolution do you have now ???

I have Resolution 1400x1050.

As far as i know i doen't have an ATI pannel installed. I just used the proprietary-driver dialogue and then restarted.

What can i enter as refresh info, to test it?

This section seems to trigger the problem.

disabling it I can restore the correct color, but at the same time lose 3D-accelleration. Seems to be a bug in the driver itself.

Wich version of driver do you have ??? If you want we can install the last ATI driver, but we do it manually !
