gnome-display-properties does not let me set up a second monitor or save the monitor configuration

[Erica Peterson]

Binary package hint: gnome-control-center

Currently running Ubuntu 10.10, gnome-control-center 1:2.31.91-0ubuntu1.

I am trying to set up a second monitor in the gnome control center. I click on the 'monitors' button to open gnome-display-properties and the second monitor has been correctly detected (correct make and model appears in the window). If I click on the second monitor and change its status to 'on' and try to drag my cursor into the second monitor, I can only see my cursor appear at the very edge of the second monitor. Yes, the monitor is on, but the screen is black, and the cursor only appears on the very edge. If I then click 'apply' in gnome-display-properties I get an error message "could not save the monitor configuration." Second monitor is a Samsung Electric Company 23" LCD; worked fine under Lucid.
