Yes, with a cable connect it is possible, of course. But i dont like it to be restricted in my movement by wired to a hdmi-cable. :-) Am 20.01.2016 um 15:07 schrieb Jonathan Billings:> On Tue, Jan 19, 2016 at 10:49:31PM +0100, Joey wrote: >> i try xephyr/xnest, but i dont recognize how i can use a nested display like >> a second screen. > I guess I still don't understand why you need a second, virtual > screen. > > Every projector I've ever used appears as a second screen on my linux > desktop, and I have the choice to either mirror my display or expand > my desktop across both.

Yes. Sometimes i go to the front like a teacher and then i go to the groupdesks. And i hate it always to go back to the front where the cable of the beamer ends only to use my device and to show the whole participants things on the beamer. This feels so much last millenium.

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 :-( maybe its possible to use a nested xserver, but i dont know how i could make xephyr or xnest available for kde as second device.
