sure enough there is no DISPLAY environment variable set. So I set it and
then the error message became:

Failed to connect to session manager: Failed to connect to the session
manager: SESSION_MANAGER environment variable not defined

I notice there are several other variables missing which do appear on
another machine with working xfce system, i.e. one still on stretch 
distribution, such as XDG_MENU_PREFIX=xfce-, XDG_CONFIG_DIRS=/etc/xdg 
as well as SESSION_MANAGER and several others.
