Jupiter is a system tray applet for controlling battery power and hardware options for laptops and netbooks running Linux. Jupiter has been designed to be a comprehensive applet for quickly toggling settings for screen output, battery power, screen resolution, Wi-Fi , and Bluetooth. Its has packages for Ubuntu, Fedora, Fubuntu and other Linux distributions.
Being able to configure and control hardware options from the app-indicator menu is much easier than searching hardware settings from the Unity Dash.
You can quickly change the video display (internal, external or both), screen resolution, screen orientation (normal, left, right and center) and other settings by clicking on the Jupiter icon from app-indicator menu. Selecting a category opens a drop down menu with configuration options.
Note: If certain devices do not appear in the Jupiter list, it is likely that you might not have the correct drivers installed for the hardware device.
When you change a configuration, a bubble message informs you of the applied changes. For example, if you change the resolution a bubble message will inform you of the new resolution size.
sudo add-apt-repository ppa:webupd8team/jupiter sudo apt-get update sudo apt-get install jupiter
For Asus EeePC netbooks, you can install jupiter-support-eee – required for SHE (Super Hybrid Engine),from this command:
sudo apt-get install jupiter-support-eee
Unity users should log out and log back in after launching Jupiter, so that changes can be applied. Once you log back in, Jupiter will appear in the system tray. You can download the Deb and RPM packages for Ubuntu, Fubuntu, Auro Linux and Fedora from the Sourceforge link given below. The Ubuntu 11.10 package has been modified by Andrew from WEBUPD8 and you can find out more about the applied changes from his website (link given below).
