I've found the solution : In the panel, just add the "indicator applet" (in french "applet de notification").
It will add 3 indicators to the panel: battery status (only on my laptop) Mail status Volume status Be careful, If you remove Mail indicator, it will also remove volume indicator, damned ! -- indicator-sound doesn't start, exits when started by hand https://bugs.launchpad.net/bugs/528589 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
