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. If you choose the second option, you can put your projector content on the projector, and keep your laptop's display for notes. Does your projector not do that? I don't understand the situation where you need to use a second computer and ffmpeg streaming. -- Jonathan Billings <billings at negate.org>
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.
