How do I make e.g. empathy autostart on login in Lubuntu 12.04?
Apparently it is well documented, http://wiki.lxde.org/en/LXSession#Au...tions_on_login

Put *.desktop files of those applications in ~/.config/autostart, and they will get executed when the session starts.
But apparently I'm a moron because I still don't get it... What's a .desktop file and where do I find them? I looked through the /usr/bin folder where I usually find installed apps not showing anywhere else, but there is no hidden files there.

Please, could somebody please explain it to me as they would to a 3 year old. Thanks.
