Yes, I forgot to mention this.

Yes, and as Prof. Ripley correctly guessed that the DisplaySize setting was 
wrong. SaX2, the X11 setup tool of openSUSE, adds up the width values of both 
Xinerama devices, which results in a wrong DisplaySize width value. I filed a 
bug at openSUSE and already got a reaction. It seems unclear whether it is 
correct to add up the values.

Thanks for the advice. Correcting the DisplaySize value helped, and it didn't 
break the Xinerama setting.
