I decided to give Ubuntu Server a try. All I have to say is wow. It is very clean cut and doesn't even come with a GUI!
I decided to install the package "kubuntu-desktop" since I'm more of a fan of KDE then Gnome. I set it up so that my winterm loads a Ubuntu distro - which is great. I'm starting to implement Citrix and would like to know if there is a Linux distro out there that pushes to a Citrix interface.
