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-sessionand, 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.
