I installed teamviewer on my lubuntu by this way :
I got a problem with terminal tho... How the **bleep** i autostart teamviewer without terminal ?
(im not pro with linux, newly installed...)
I don't understand how your question is related to the topic you linked, as it does not talk about autostart.
I think what you want to do is, open Extras / Options and enable "start with system" in TeamViewer. It should then start automatically the next time you log in.
