Hi there,
imagine a medium sized office room, where four engineers hack away (all of them currently have Fedora 22 workstations, to stay on topic.) On that room there's a fifth PC, hooked to a big TV on the wall (also running F22) that has Firefox running full screen with some visualization of sorts (dashboard thingy). Those five computers are all on the company wired network... nothing you haven't seen a thousand times before.
Now, Sally, one of the engineers wants to share her desktop with the others and uses application XYZ to project/cast/extend/send it to the big TV (via its PC, of course). All of them discuss whatever was on her mind, and five minutes later, she closes application XYZ and the office goes back as it was before. Fred wants to do the same, and he does. Actually all of them can.
They asked me what is XYZ.
I was thinking on a member of the VNC family, but what they want to do is the reverse of what one normally do with VNC. To make things more... interesting? XYZ must never go out of the corporate LAN and if it were Open Source, the better.
Any ideas on XYZ?
Best regards, Amit.
PS. Erm... one last thing. If there's a solution, could it include sending the audio as well?

It seems you want to screencast, something like chromecast I guess, but interactive sessions. I do not know of any such program. I can think of two hacks though.
1) You can use your company's video conferencing setup to screen share with the desktop with the big TV.
2) Just unplug the TV from the desktop and plug your laptop in, and extend your display. I have a script that will automatically pick the optimal resolution for the display using xrandr. You can write something like that yourself (or if you like the idea, I can send my script).
Hope this helps,

You are right about that. The closest existing thing, as far as I know, is an Android device miracasting to a TV. Note, however, that the remote display is dumb, in the sense that for as long the remoting session is up, it will do nothing but show the desktop.
Thanks, Amit.
Hey,

So, got any solution for this? I'm also interested...
TIA, Carlos.

One of the advantages of Pulse Audio (now that it seems to work!) is the ability to send two video + audio paths to different monitors, specifically by an on-board sound chip and a GeForce video card with sound sending its video to a local monitor, and video + audio output to a TV via an HDMI port. (Local sound comes from the mobo chip.) I too have a TV in different room, and I ran an HDMI cable thru a short piece of PVC pipe thru the wall to the TV. You will need a method of preventing the display from timing out. Lisi recommends inputting xset -dpms. I haven't tried that yet, as I won't be home until the end of the week. If that doesn't work, a mouse jiggler will.

I have not tried this, but you can run the vnc viewer in "listening" mode on the big screen tv, then run vncconnect on a workstation to connect an existing vnc server there to the viewer. Could be worth a try.

Wow... I didn't know PulseAudio was able to do that. Must check the docs...
Thanks a lot, Carlos.

Is this the same idea or mechanism as reverse vnc? Or "tech support mode", as sometimes can be found?
I think it could work, yes.
Thanks a lot, Carlos.
