Jupiter, an applet originally created to work with Eee PC, was later turned in to a life saver, or I should rightly called, ‘power saver’ for many Ubuntu (and other Linux distribution based on Ubuntu) users. If you have used Ubuntu for some time you might have realized that the laptop battery on Ubuntu lasts less than half than what it is on Windows. Jupiter is the best tool to improve laptop battery life and overheating on Ubuntu.
Jupiter’s developer Andrew Wyatt announced the demise of Jupiter today. Andrew says that majority of the problem that Jupiter initially aimed to solve such as multiple monitor support, WIFI / Bluetooth radio control etc are already fixed in one way or another and its only task now is to tune the kernel for the applied power state.
Today however the majority of the problems that Jupiter was created to either work around or solve have all been fixed upstream or are no longer as useful as they once were; like multiple monitor support, WIFI / Bluetooth radio control, and Eee PC specific support for things like a scaled 1024×768 resolution. Today, Jupiter’s remaining valued feature is simply its ability to tune the kernel for the applied power state.With that said, I would like to announce that I am retiring Jupiter Applet effective today. The kernel tuning functionality has been merged into the Fuduntu Linux distribution thus rendering Jupiter itself completely obsolete.
Andrew, not every one uses Fuduntu but I respect your decision to stop its development. As for the Jupiter users are concerned, Jupiter will continue to work as previously so you need not to remove it from your computer now. It may be incompatible with future versions of Ubuntu.
There is no doubt that Jupiter will be missed. We will see in coming days what can be done to manage power and overheating issues in Ubuntu in coming days.
