I've just installed cpufreqd in a fresh installation of Ubuntu 14.04 through:

sudo apt-get install cpufreqd

After that, I tried to execute it by sudo cpufreqd. But nothing happens (neither error or indicator displayed). Even I can't see any new process in the system monitor.
Then I installed cpufrequtils through sudo apt-get install cpufrequtils and I tried again to execute sudo cpufreqd with the same (no) result.

I know there exist indicator-cpufreq, I was using it for some time; but I realized that I need something more configurable and complete like cpufreqd.

Similar alternatives to this are welcome.

indicator-cpufreq is what you need for the panel

The daemon is the core part and plugins (I only know the panel one though ;)) let you have control over what, when, how. The indicator is one of those plugins (and the easiest one).

cpufreqd is started automatically after installing. For it to work you need either APM, a recent ACPI or PMU. And the modules cpufreq_powersave, cpufreq_userspace, and cpufreq_ondemand (you need to load these for cpufreq to work). It has a configuration file that explains all the different settings in /etc/ and has samples. What is best for you is up to you to decide ;)

An alternative would be TLP.

Just a warning: the tools for management should already be in the kernel (and working). It is called "laptop-mode-tools".

  • Now, I messed up something and doesn't matter which governor or frequency I select, the cpus are always in 2.90GHz (the maximum). Is there any way to reset the cpufreqd.conf and any other configuration file for this to the default values?? – Akronix Apr 26 '14 at 18:15

    99% chance that means the modules are not loaded. check with "lsmod" if they are. – Rinzwind Apr 26 '14 at 18:34
  • Hello @Rinzwind, thank you for your help. Here output for lsmod: http://pastebin.com/DSTSd2NG Here output for cpufreq-info: http://pastebin.com/QszeTYMj – Akronix Apr 26 '14 at 18:38
