The bidirectional clipboard mode doesn't break with the Linux 
in either MATE desktop or Plasma 4 desktop. I'm using x2goclient 
on Fedora 27 client machine.

I used PuTTY's X11 forwarding/tunneling to do this. The bidirectional
clipboard mode breaks in the same way with this method in both MATE
desktop and Plasma 4 desktop.
