Jupiter – Light weight power and hardware control applet

Sponsored Link
Jupiter is a light weight power and hardware control applet for Linux. It is designed to improve battery life of a portable Linux computer by integrating with the operating system and changing parameters of the computer based on battery or powered connection.

Additionally, Jupiter provides quick access to some of the commonly needed hardware controls like screen output and resolution, WIFI, and bluetooth.

If you use Linux on a portable computer, let Jupiter take the effort out of going mobile.

How to change CPU speed display in Fahrenheit

By default the temperature in Celsius is hard-wired into Jupiter.

If youwant to change CPU speed display in Celsius to Fahrenheit use the following procedure

First backup your copy of existing jupiter configuration file

cp /usr/bin/jupiter ~/jupiter

Next edit the file:

gksudo gedit /usr/bin/jupiter

Find the following section in the file:

def get_temperature(self):
temp = int(self.collect_data(self.temp))
temp = temp / 1000
return str(temp) + ‘ ºC'

change to:

def get_temperature(self):
temp = int(self.collect_data(self.temp))
temp = temp / 1000
temp = ((temp * 9) / 5) + 32
return str(temp) + ‘ ºF'

Save, logout and login.

After changing this you need to disable your jupiter PPA otherwise when you update next time this will overwrite this change

    I have this app installed and it is great…apart from 1 thing. If you have set video displays to external on your laptop…and you take away your laptop without remembering to change the video setting to show both external and internal, then when you log on you end up with a blank screen and no way (that I have found yet) of getting your screen to display.

    Installing this screwed up my sudoers file.
    I kept getting these awful errors, and couldn’t use sudo. I had to reboot into recovery mode to fix it.

    It had appended a line that starts with %jupiter ALL=NOPASSWD: …
    But instead of creating a new line at the end of the file, it put it at the end of the last line.

    It should have checked to make sure that it was on a new line before appending to the file. I was seriously confused about what was going on for a while. MAJOR bug!

    I installed Jupiter in my notebook and netbook. It was OK with the notebook Dell XPS. However, my netbook Asus eeePC 1201T became veeeeery slow (e.g., more than 5 minutes to finish the boot AFTER typing the login password — and it was really slow in all the programs I worked, like browsers and LibreOffice). I tried to uninstall the package jupiter-support-eee but the problem remained. So, I uninstalled jupiter and everything became OK again.

    Hi, u can download the deb package from here:


    then, via root user, type in terminal:
    dpkg -i jupiter_0.0.50.2_all.deb

    and you are done.

    However, i still havent figured out for it to start automatically on startup.
