I do not know if this is still an issue with the newer versions but, in
older versions of X2Go Server on some distributions, one needed to have
started X before hand.  We never fully resolved the issue but it wasn't
that X had to be running.  It was that starting X started some process
which X2Go needed but could not start as a non-privileged user.  If you
start X from the console, even if it fails, does that now enable you to
connect using X2Go Client? - John
