On the powertop page of archlinux wiki it says:
There are two ways to automatically apply the suggested settings:
- Recommended: You can apply these settings at boot by using module parameters, udev rules and sysctl. For details, see the power management page.
- You can use the --auto-tune feature from powertop which sets all tunable options to their GOOD setting. This can be combined with systemd service to have the tunables set on boot. Remember to enable/start the service.
Currently I use the second method.
I have 3 questions:
- Will the results be identical?
- Why is the first way the recommended one?
- How exactly to implement the first method?
Also, a comment on this post post says:
No need to install powertop, just install and run TLP. Feel free to check the variables in powertop afterwards, they'll already be activated by TLP. :-)
If I already use tlp does it mean that it applies the powertop sugegsted settings by itself? Or, to ask differently: do I need powertop if I use tlp?
On the TLP webpage there is a note:
On the other hand, attempting to run
powertop --auto-tuneon each boot may overwrite TLP’s settings depending on the actual boot order.
Is it a bad idea to apply powertop settings at boot?
