rotate screen on fx5200
i just installed a new Sabayon linux on a system with a FX5200 card. I'd like to rotate the screen 90 degrees to portrait, but don't see how.
the nvidia x server settings app doesn't have rotation settings.
RandR desktop applet let me change resolution, but not rotation.
Option "RandRRotation" "true" and Option "Rotate" "CCW" in screen section in xorg.conf don't work...
