OpneSuSE11.1 - Dual Head not working

Hi everybody,

just installed OS11.1, everything’s fine - only my second display doesnot work. While installing it runs as a “double” of the first, after installation it shows fancy colours and patterns.
(NVidia7600GT, 2x Benq 19" monitor). The hardware information shows the second monitor correctly, but the “grafic and monitor property” of sax2 does not show a second display…

what’s gone wrong?
