I need for my users to be able to easily login remotely (with desktop GUI) to my brand new Ubuntu 12.04. I have searched the web and found tons of information about VNC, Vino, FreeNX, Citrix etc. However I am not very tech-savvy and cant really figure out what I need and how to get it up :-)
My users come from different platforms, some from Windows and some from Mac OS X. What software should I be looking to get them to be able to remotely login to desktop on my server?
Also I found several places talking about enabling Remote Desktop som the System->Preference->Remote Desktop
But I cant seem to find such a thing :(
Id be really thankful for any help!
