The $STARTUP env variable will be set for every Xsession based X11  
session on a Ubuntu or Debian (and alike).

Please do a grep on /etc/X11 and see its output (grep -r STARTUP /etc/X11).

In case you want to use $STARTUP in your own scripts, please know that  
it is not a good idea to use that var name on Debian nor Ubuntu systems.

Using X2GO_STARTUP or any other variable name will not work with  
existing scripts in /etc/X11/Xsessions.d. Thus, closing this issue and  
tagging as "not-a-bug".

Greets,
Mike
