In Ubuntu 10.10, I added the CPU scaling applet on my panel in order to control the CPU frequency scaling. Since Unity no longer has a panel that supports applets, what mechanism do I use in 11.04 to achieve the same goal?

There's a special app-indicator, Cpufreq.


Install Indicator-Cpufreq

I hope this helped you,


  • It's unfortunate that it's neither a part of ubuntu (a PPA), nor something that can be added easily (without running alt-f2).

    @Mike You could add it to your startup applications so you don't have to start it every time

  • the only thing this app lets me choose from is powersave and performance. nothing else.

There is also a program called jupiter.


Download: http://sourceforge.net/projects/jupiter/files/

  1. 3 perfomance mode
  2. disable wifi/bluetooth/touchpad
  3. change screen resolutions
  4. rotate the display
  • the question asks explicitly for something that works with indicators.

  • The question does not include "indicator". Question asks for a "mechanism". Nevertheless it does what is asked for and works better than any other I have used.

    I think it is a good answer because it makes people aware of more/other alternatives that may suit them better. Even if I do agree with that the answer mentioning the indicator is superior, IMHO. May 4, 2011 at 8:36
  • ok fine, the question explicitly asks for something that works outside gnome-panel, or rather, something that works with Unity. Your screeshot looks nothing like Unity.

    Btw there is a PPA for this: ppa:webupd8team/jupiter

you can also create a launcher. Right click on desktop, select "create launcher" name it, icon it, and put "indicator-cpufreq" as the command. then drag it to the unity launcher. I have a folder in home which keeps my desktop free of launcher clutter while the applet war wraps up.


I know this has been answered already, but I found this link very easy to install the CPU Frequency Scaling.

    Whilst this may theoretically answer the question, it would be preferable to include the essential parts of the answer here, and provide the link for reference. Jul 22, 2012 at 21:10
