Jason Conti has ported the Gnome Indicator Applet to work with GNOME 3. It can now be used with fallback Gnome. Included is an Ubuntu Appindicator, Date/Time Indicator, the session indicator, network, Ubuntu Sound Menu, Messaging Menu and if you choose, the Global Menu too.
The indicator applets can be installed from the PPA by running the following commands in the terminal:
sudo add-apt-repository ppa:jconti/gnome3
sudo apt-get update
sudo apt-get install indicator-applet indicator-applet-complete indicator-applet-session
To install the Global menu too, run:
sudo apt-get install indicator-applet-appmenu
Once everything is installed, you will need to remove the existing applets. To do so, press the Alt key and right click the panel. Select remove from panel.
Next press the Alt key and right click again, and select add to panel.
Add the Indicator Applet Complete.
