Gnome "Screen Resolution" Manager does not detect multiple monitors


Hi,

The new Ubuntu (Hardy, that is) comes with gnome-display-properties, which is supposed to be able to detect multiple monitors and configure them, but it's not doing that for me. I can only see one monitor in the config window, and it is labeled "Unknown". It lets me change the screen resolution just fine, but I can only use one of my monitors.

I am using the proprietary NVidia drivers with a nVidia GeForce G0 7600 on a laptop. One of the monitors is the laptop's built-in LCD and the other is an external LCD connected via VGA.

Another note: I can use nvidia-settings to activate and switch between my monitors, but this has some ugly side effects, like fullscreen apps being shrunken down to a little box on a black background, and Gnome windows and panels not snapping to the edges of the screen.


This is my current /etc/X11/xorg.conf:

# nvidia-xconfig: X configuration file generated by nvidia-xconfig
# nvidia-xconfig: version 1.0 (buildmeister@builder3) Wed Sep 12 14:29:35 PDT 2007
