Ah well. Seems like that part of X2Go Server is highly Debianic  
then... Sorry for that.

The /etc/X11/Xsession.d is a place on Debian systems where other  
package (maintainers) can drop in code that should be executed with  
every Xsession startup.

I attach a tarball of all those script on my Debian wheezy system to  
this mail to give you an impression of what is going on in Debian's  
/etc/X11/Xsession.d.

The last script being executed looks like this:

"""
# $Id: 99x11-common_start 305 2005-07-03 18:51:43Z dnusinow $

# This file is sourced by Xsession(5), not executed.

exec $STARTUP

# vim:set ai et sts=2 sw=2 tw=80:
"""

Greets,
Mike
