In our previous article, we took a look at the Ubuntu Linux Unity launcher. On the right upper corner of the desktop you have application and system indicators.
|Ubuntu Linux 11.10 Unity Desktop
Ubuntu calls the information area the Application and System indicators.
Clicking the icon of the right most point of the bar gives you access to settings, informs you if updates are available or it you need to restart your computer, switch between accounts and "power" down your system.
From here you can configure your instant messenger, email, check your battery life and configure power settings, Bluetooth, WiFi and speakers. On the computer in the screen shot, Dropbox has been installed and the indicator icon shows up on the same area.
Notifications from your email, messenger apps and system will pop-up in this area.
