How to use Jupiter with Ubuntu 11.10 to control netbook power features


The Jupiter applet for Linux has offers netbook users a way to control the clock speed of Intel Atom chips and some other advanced features. Jupiter has been available for a few years, but up until recently there was no easy way to use Jupiter with Ubuntu 11.10 Oneiric Ocelot.

That’s not a huge surprise, since Ubuntu 11.10 won’t officially launch until October, but beta versions of the popular Linux distribution have been available for a while. Now the folks at WebUpd8 have put together instructions for installing a hacked version of Jupiter that supports Oneiric Ocelot.

Basically you need to download the special version of Jupiter from the WebUpd8 repository, install a custom Eee utility if you’re using an Asus netbook, and you should be good to go.

Once installed, you can use Jupiter to change the clock speed of an Intel Atom processor to adjust for “power saving,” “high performance” or “maximum performance” modes. High performance is basically the default clock speed, while power saving underclocks the processor a bit to offer better battery life and maximum overclocks it by a small amount to give you a tiny performance boost.

Jupiter also gives you quick access to other settings including the screen orientation, screen resolution, and wireless options for many netbooks.

    ONE big problem with this Juniper, is that it used MONO, and guess what, that is a big Microsoft Patent problem.  So, best to avoid using it period.

    It it was written in something else, with a FREE license, then ok.
    Mono is to be avoided at all cost.  Don’t even put it on your Linux system at all.

      There is nothing wrong with Mono except that it’s made by Microsoft so anontrolls hate it.

      Just ignore them.

      To be blunt. Those “assholes” at Microsoft put the fucking desktop on the map. Without those “assholes” I’m pretty sure we would be seeing Acorns, Sinclairs, Apple, Commodore…one thing that we WOULD NOT be discussing is Jupiter or anything related to Linux.

      So to use my politest french, please kindly shut the fuck up.

    Anon, STFU. There’s nothing wrong with mono. Grow up.

    That was helpful.. I wonder if there is an official version of Jupiter for 11.10 now?
