How to easily hide the username on the Unity panel

By default, Ubuntu displays one's name on the Unity panel in the top-right corner, but, for various reasons, there are persons more conformable with a no name/no face top bar.

Hiding the username is a simple task, which can be easily accomplished via dconf-editor:

• first, install dconf-editor
  

  sudo apt-get install dconf-tools

• then, open it and navigate to apps-->indicator-session and, on the right-side, uncheck show-real-name-on-panel

Finally, reboot your PC.

To undone the above action, repeat the scenario and check show-real-name-on-panel.
