I am using Ubuntu 10.04 LTS. When I attach an external monitor the default is that the new monitor is placed to the right of the samsung n150 netbook I am using. This opens the desktop back ground on the screen, not duplicates though. When I go to System>preferences then monitors and change the screen to be on the left, the desktop background disappears and I cannot set it so that the background is still there.
My goal is to be able to rearrange the relative positions of the monitors without the desktop backgrounds being distorted.
