Since Freenx doesn't seem to be easily installable in Ubuntu 14.04 servers (at least up to the time of this writing {sign user="Xavi" datetime="2014-10-24T13:01:06+00:00"}). Therefore, we can use an open-source equivalent alternative, called __x2go__ (x2goserver and x2goclient), which is maintained for GNU/Linux based servers, and with supported clients for GNU/Linux, Mac and Windows.
Quick howto to turn your machine into an X2Go server:
{CODE(colors="shell")}
sudo apt-get install python-software-properties
sudo apt-add-repository ppa:x2go/stable
sudo apt-get update
sudo apt-get install x2goserver x2goserver-xsession
sudo apt-get install x2gomatebindings # if you use MATE/mubuntu
sudo apt-get install x2golxdebindings # if you use LXDE/lubuntu
{CODE}
You also need to install some desktop environment which is supported by X2Go by default, and in our case, we will install one of the lightest desktops possible: __LXDE__ (see http://wiki.x2go.org/doku.php/doc:de-compat for the full list)
{CODE(colors="shell")}
sudo apt-get install -y lxde
{CODE}
__Notes__:
* Remember to install x2goclient in the client computer in order to connect to the server accordingly.
