You can use ps to find out wich programs are currently running.
Here is the result from my system:

% ps ax | grep stump 
 2299 ?        Ss     0:02 /home/stefan/work/git/stumpwm/stumpwm
 2333 ?        Ss     0:00 /usr/bin/ssh-agent /usr/bin/gpg-agent --daemon --sh

stumpwm.desktop is used to declare a window manager for GDM. These
entries are not propagated as environment variables.
