I haven't had an idea how to help further, thus kept quiet.

This is interesting though - and could explain your problems.


First of all, you shouldn't set LD_LIBRARY_PATH at all. The new X2Go Server
versions don't do it and you shouldn't either. /usr/lib/x86_64-linux-gnu in
there should even be fully redundant and messes with the default linking order.
Not just that, but it means that our DT_RUNTIME trick in nxagent, which is
supposed to override libX11 linking against a compatibility symlink (libX11 ->
libNX11) installed in a specific directory, is not working - hence loading the
wrong libX11 library and thus leading to nxagent failing to open its internal
display.

Be careful when you mess with stuff with that.
