Hi List,

I really would appreciate your help, because I ran out of ideas!

Basically dual-head works, but only with a little workaround:
If I start X, with the xorg.conf I attached, the second monitor simply 
isn't activated, although the desktop is expanded to the second monitor! 
I first have to comment out "Screen 0" and "Screen 1" within both 
'Section "Device"' for Card0 and Card1. If I then start X, the second 
monitor is activated in cloning mode. After "reaktivating" the "Screen 
0" and "Screen 1" entries, which I just have commented out, dual-head works.

Do you have an idea what is wrong in my xorg.conf? I "played" around for 
example with commenting out "Xinerama", removing the second 'Section 
"Device"' for Card1, but without success.


Kind Regards,
Benjamin
