Package: x2goclient 
Version: 4.0.5.0 

There is a problem when using a x2go session (in both "Publisshed apps" or "Desktop / MATE" mode ... didn't tried on other desktops) and trying to do bidirectional copy/paste from a Windows client (Windows 7 SP1 / x2goclient 4.0.5.0).
It seems that the "copy on select" features is overriding the primary clipboard which makes the copy/paste pretty difficult if not impossible.

How to reproduce :

Local : Windows 7 SP1 / x2goclient 4.0.5.0 in Published Apps ou MATE Desktop mode (but windowed or fullscreen on 1 dedicated screen, not complete fullscreen)
Remote : Ubuntu 14.04 / MATE Desktop with x2goserver 4.0.5.0 and x2gomate-bindings

From Windows, copy some text in Notepad then, on your x2go session (let's say with Pluma or Gedit), select some text you want to replace (just select, not copy) and try to do a paste, that won't work and your clipboard now contains the text that has been selected in the x2go session.
You can even paste it in Windows (but strangely, not in Linux where the clipboard seems empty).

This is very very annoying especially for our use case where our x2go sessions are used as developpers sessions in Published Apps mode and they do plenty of copy/paste all day long.
We moved recently to this infrastructure but this doesn't help its acceptancy due to this bug.

I tried to check the "do not use primary clipboard" in the client preferences but this makes the xserver fails to start (see bug #906), I even tried to add the -noprimary or the -noclipboardprimary that are described here (http://code.x2go.org/vcxsrv?p=vcxsrv.git;a=blob;f=xorg-server/hw/xwin/InitOutput.c;h=5a3d80f7fe17d2e81f634ba80d0494451653b637;hb=934184bfecd402aae891b8740d788b486aa7269f#l722) but that dosn't work either, it seems these options are in the usage help message but are not supported at all so I don't know if using them is helping or not.

Best regards,

Walid Moghrabi
