This tutorial shows you how to install Unix's xfce4 desktop onto your server. Though this desktop version will not allow you to set up printing though it, it will allow you to mange your file system a little easier. I sugguest turning it off when you are not using it though.

Explanation Screenshot
First update Ubuntu using the command: sudo apt-get update Open Terminal
Next enter the command: sudo apt-get install xfce4 Enter y when nessary. Open Terminal
Now you restart your machine, I prefer to do this to ensure all files are saved. This screen will appear after you enter your password, select Use default config. Open Terminal
You can access the terminal appliction by going to, Applications Menu --> System --> Xterm Open Terminal
Once you have the terminal application open you can enter the command: sudo update-rc.d -f gdm remove This will remove any startup directives that are in the configuration files, and keep the GUI from starting when the server is started. Open Terminal
You can now restart your machine, and you will log into it as normal. Open Terminal
Any time you want to start the GUI, just enter the command: sudo startxfce4
Now you have installed a GUI on your server that you can use to easier navigate the file system if you so please. Just rember to turn it off once you are done, since all the extra code needed to run the GUI presents a security risk.
Open Terminal
