I'm not sure what your point is. None of that addresses the root issue that the thread starter mentioned, or that I confirmed.
And as I said, restarting x2goserver, which restarts x2gocleansessions, usually allows the Windows client to resume the session. I don't know why, but it is a fact that it usually does the trick for me (although not always, I'd say its around 90%)
I am not going to contact the Archlinux package maintainer and tell him where to put the binaries, since as far as I am concerned, he can put them wherever he likes. You are welcome to contact him if it bothers you.
