Im running this server through Putty and VNC viewer. im running ubuntu 14.04 LTS

Whenever I use the command "sudo apt-get install unity" in the terminal and in the Putty console It just says its already updated to the newest version. Another thing I dont understand is why I dont have anything at the top right hand side of my screen like the "log off" button or the Side panel with all the icons as seen in the first picture (the second picture is literally my ENTIRE server box) I feel like im missing something.
