Nitrux includes energy-optimizing software like Powertop and power-profiles-daemon.
To adequately use Powertop, run it while using the battery so its auto-tune functionality creates the file “saved_results.powertop” in /var/cache/powertop.
To do this, run the commands below.
- 🔰 Information: When using Powertop for calibration, it will toggle various functions, such as the backlight or WiFi. As a result, it may turn your screen black for a while, cause a network connection loss, etc. Do not touch the machine during the calibration.
- Check the available options in Powertop by running the following command
powertop --help.
sudo overlayroot-chroot mount -t devtmpfs dev /dev powertop --calibrate sync umount /dev exit
Important Notes
Powertop needs to run 370+ measurements before it can display accurate power-usage estimates. Each lasts 20 seconds, meaning Powertop must run for 1h30 in total.
