NVIDIA driver 1.0-5336 - Rotate

Hi, I've just acquired Suse 9.1 and installed the above-mentioned driver. The Suse people told me that to activate the rotate function I had to set the Option 'Rotate' in the XF86-Config to 'CW' or 'CCW'. Unfortunately that doesn't work. Could someone please tell me what I have to do so as to be able to rotate my monitor? I' d also like to know how to integrate that function into the tool in the systray which allows to change the resolution of my screen. Grateful for helpful hints Jürgen
