Virtual Display have different meanings.

i need a solution like a dualscreen. i want to move with mouse windows from one screen to the other. and i need that i can stream the 2. screen for example with ffmpeg. with ffmpeg i can stream a part of the desktop (also the second screen)

i try to use the panning function of x-server. but with panning (desktop larger then monitor) the controlpanels and widget of the screen are resized and spread to the whole desktop. after resize a lot of preferences are destroyed :-(

It sounds like what you want to do is use Xdmx (xorg-x11-server-Xdmx package) with maybe x11vnc on the system hooked up to the projector.
