Version: 4.1.0.0-2017.03.11

Using latest Arctica's NX-Libs xrandr support is far better and multihead support in fullscreen mode with the Linux x2goclient works like a charm.
For example, with MATE, the panels are restricted to the first screen and the second one is acting like a real secondary screen in extended desktop mode with working boundaries when putting applications in fullscreen (ie. they don't extend to the whole display as before but they are restricted to their including screen).

So with the Linux client installed on a desktop (I'm personaly using Ubuntu 16.04 + Unity desktop) it works great whereas, in TCE / Displaymanager mode, multiple monitors are supported but the desktop is stretched as if it was only one big screen and not 2 separated screens.

Any idea why, using the same base OS and libs (Ubuntu 16.04 + X2Go client "Heuler" + Arctica libs) I get different multiscreen support ?
I think this is related to randr support but I don't know what differs and why it behaves differently on one case and the other.

Walid Moghrabi
