One thing missing from Freya out of the box is adequate power management tools. This isn’t a problem if you’re using this agile linux distro on a desktop but can be critical when using Elementary OS on a laptop. Here’s a quick and dirty setup to get you the bare minimum power management on your fresh Freya install.
NOTE: add ppa’s at your own discretion. Alternatively you can simply download the packages.
- Install tlp…
sudo add-apt-repository ppa:linrunner/tlp && sudo apt-get update sudo apt-get install tlp tlp-rdw
- Then install powerTOP…
sudo apt-get install powertop
- Calibrate powerTOP (this will take a while and many strange things will happen… walk away)…
sudo powerTOP --calibrate
- Check the report with (hint: the
powertop.htmlfile will be saved to the root of your home folder)…
sudo powertop --html
- Open the
powertop.htmlfile and check out the suggestions under the Tuning tab.
- You can write the script suggestions to your
/etc/rc.localfile or if you trust everything that powerTOP says, you can just add the line
With just this most basic of configuration you should be able to squeeze out more juice from your average charge cycle.
