Hello Linux Users.
Because Ubuntu 13.04 Raring Ringtail has been just released, the Ubuntu 13.04 tweaks are very popular this time:
By default, displaying your username in the Unity Panel is disabled in Ubuntu 13.04.

To add your username on the Unity Panel, do this:
$ gsettings set com.canonical.indicator.session show-real-name-on-panel true
To remove your username from the panel, do this
$ gsettings set com.canonical.indicator.session show-real-name-on-panel false
This tricks works also for Ubuntu 12.10 and Ubuntu 12.04.
