just because something is installed doesn't mean it is running. You need to run your vnc server to connect to it. Presumably you automatically start it when you log in to the desktop.
If you want to use vino for vnc, and have it autostart after boot, then you should consider configuring your display manager to automatically log you in when you start.
Please note that I don't use vino, but from your description of the problem, I think this approach should work.
