there was a follow-up commit to the one you quote:

Unless you shoot the client with kill -9 it should indeed run  
x2gosuspend-session on the server before quitting. I would consider  
that as a minor bug, as well.

Double clicking the session should work. So should the resume button.  
Resuming of a running session should be a sequence of  
x2gosuspend-session call on the server and then a x2goresume-session  
call for that same session. Between the two calls you need some time  
for the session to change its state (couple of secs).

If you could come up with a patch, that would be really helpful. The  
last patch you sent was accepted. So will be a follow-up patch (at  
least it's very likely!!!).
