This could be one puzzle piece, indeed. Basically, we can kill  
x2goruncommand and then the session manager would automatically go  
into logout.

However, esp. the GTK desktops (MATE, XFCE, etc.) leave many stray  
processes around (e.g. gvfsd, colord, etc.). For these friends, some  
more intelligence is required. Might have that in the X2Go Server  
renicer code already, because Lee at those early times worked on code  
that detects the complete process tree of a running desktop session.

Nowadays, one could argue that cgroups are another and better  
alternative. But cgroups are not available on non-Linux, so maybe a  
kernel-agnostic approach is a more favourable way to go?
