Creating Additional Desktops

New desktop environments are created using the vncserver utility. If vncserver is not already installed, it may be installed from a terminal window as follows:

sudo apt-get install vnc4server

Once the VNC server package is installed, the next step is to assign a password to protect the desktops. This can be achieved using the vncpasswd tool. Run this tool from the command-line prompt in a terminal window and enter the password of your choice.
