How do I stop VINO ? - or all GUI related programs for that matter.... (Xubuntu)

[flameproof]

I want to close all GUI related applications and run Xubuntu as a pure webserver and control it via SSH. I want to control that then with a start.sh and stop.sh script.

First issues I face, how do I stop vino-server? This does not work:

/usr/lib/vino/vino-server stop

And while I am at the topic, what else I can close down, and how?

I guess XCFE is not needed too. How do I close that?
