To get VNC running, you just need to install the tightvncserver package.
sudo apt-get install tightvncserver
Then to run, use the following command.
After running the command, the terminal will display the hostname and display VNC is operating on. That’s it! Your pi now has a VNC server running on it. This tutorial goes into detail on how to set it to run on startup.
I use Chicken of the VNC on my MAC as a client to connect to the server.
