OK, I have tested all this now. It is tricky because the old nxclient
requires some more stuff like ~/.x2go/config/nxclient.cfg. I have not
bothered fiddling with this and came up with a different/nicer
solution instead: neatx. It is working nicely here. This is what I
have done (in addition to the steps mentioned before):
1. download and extract
https://storage.googleapis.com/google-code-archive-downloads/v2/code.google.com/neatx/neatx-0.3.1.tar.gz
2. cd neatx-0.3.1
3. apt install python-docutils, maybe you need to install some more,
see INSTALL file
4. ./configure --prefix=/tmp/neatx (you can choose another path if you want to)
5. make && make install
6. create a small wrapper (/tmp/nxclient in my case) with this content:
--------------------------------
#!/bin/bash
PREFIX=/tmp/neatx    # adapt to the same value you used above!
PYTHONPATH=${PREFIX}/lib/python2.7/site-packages
/tmp/neatx/lib/neatx/nxdialog "$@"
--------------------------------
7. chmod a+rx /tmp/nxclient
8. adapt NX_CLIENT in x2gostartagent to point to the wrapper
9. run a new session -> menu working, keystrokes open request windows
(see attached screenshots)

@Stefan: maybe we should include this component from neatx into the
x2go distribution. What do you think?
