Jupiter adds power management to Linux netbooks
Some netbooks, already come with a built in power management application but, if you’ve installed Linux on top of the default Windows operating system, you will have been missing out on being able to easily switch from high performance mode, to power saving mode. This however, is where Jupiter comes in. The Jupiter power management applet runs in the system tray, where you can then easily switch between maximum performance or high performance, as well as power saving modes. From Jupiter, the screen resolution and orientation can also be easily changed. Adding more power saving features, Jupiter also allows you to quickly disable WiFi, bluetooth and webcam.
The Jupiter app should work on Ubuntu and any other Debian based Linux operating system. The app is based off of the EeePC ACPI utlities, which is found on Eee PC netbooks.
