NXServer is a very fast remote desktop (free) product - way faster than X or VNC. Since my core is in a closet, I'd like remote access and since I'm a lame *nix user, I like my GUIs. For this same reason, I find Webmin is a great linux administration tool. Unfortunately startup scripts and the like don't work with pluto/mce (until we make it more of a kubuntu add-on).
Anyway, I recently reinstalled again and did not put NX or webmin on. I am trying to keep it as vanilla as possible.
