set a Power Profile from terminal

[harshit9715]

I am trying to disable few cores and reduce frequency when I close the lid.

Hi, I am able to run a script when I close my laptop lid.

I was wondering if I can switch power profiles (custom ones) using CLI.

Actually, it's possible. You just have to know GUID of a custom profile. Unfortunately, there is no such info in GUI yet but you could take a look at dconf-editor or dconf and find desired GUIDs for your script:

dconf dump  "/org/gnome/shell/extensions/cpufreq/"

# YOU CAN USE IT like this:

$ cpufreq-application -p efd73d3a96e8e59fc8cbb3625c8a4b5b

# OR

$ cpufreq-application -p efd73d3a96e8e59fc8cbb3625c8a4b5b --no-save

# (to switch without remembering)

$ cpufreq-application --help
Usage:
  cpufreq-application [OPTION...]

Also, you can use cpufreqctl for tuning CPU parameters from user space.
