just a short update, the crude approach I had tried
(hacking /usr/bin/nxagent) seems to be working.
I just had made the mistake of typing "-clipboard no" instead of
"-clipboard none" or "-clipboard client".

I will have a closer look at editing the x2gostartagent to read 
x2goserver.conf, but I don't know if I'll succeed at this point.

Many thanks,
Kris
