This is a little trick for those who use Unity but do not want our user name is displayed in the panel. It is a very simple process but we have to resort to the infamous terminal. We write:
1. Gsettings September com.canonical.indicator.session show-real-name-on-panel false
2 unity -. Replace
If the second command does not work, reset our session and resolved.
Note: To leave everything as it was wrote: gsettings September com.canonical.indicator.session show-real-name-on-true panel
