I am trying to use an ubuntu 14.10 laptop with a large screen (2 monitors actually) which size is way larger than its graphics card limits. So I thought to use it via LAN (1Gb/s):
with "ssh -X ..." I can start applications on that laptop from a kubuntu 15.10 desktop PC (which has powerful graphics) connected to the large monitors and see those applications on them.
But now I would like to open remotely the entire gnome session.
I tried KRDC from the desktop but I can only join the current low resolution session running on the laptop, getting a window of its screen size.
Then, on the desktop, from the console CTRL-ALT-F2, I executed this:
sudo ssh -X username@192.168.1.2 gnome-session
but it did not do anything, just return to local prompt.
My questions are:
- Is the use of "ssh -X ... gnome-session" a reasonable way to do it and I should just try it harder?
- I would prefer to have that gnome-session on a resizeable window (like a virtual machine) to be able to use other applications on the desktop at the same time. Is there a way to do it?
- Is there a simpler way? (I have seen hw adapters to connect USB3 to 2 2560x1600 monitors, but are quite expensive and I have no clue if they work well with ubuntu and about their image quality).
Many thanks,

no, you can't use X11 forwarding in ssh for whole desktop environment. You might use the native X protocol, but it is usually painful. – Jakuje – 2016-01-30T19:24:46.253
Thanks @Jakuje. Any clue about where to learn more about how to use that native X protocol for my use case? – Yandot – 2016-01-31T12:55:48.710
