auto-cpufreq VS System76 Power Management

github repository

git clone https://github.com/AdnanHodzic/auto-cpufreq.git cd auto-cpufreq && sudo ./auto-cpufreq-installer

I know that Pop os doesn't recommend installing tlp because it might interfere with system-76 power, Is it the same for something like powertop or auto-cpufreq?

The device had only been purchased ~1-2 months ago so I don't think that dust in the fans would be an issue (as suggested in another post; Intel NUC's overheating - Solution!). The installation of Linux is more or less fresh, the only thing (I think) installed that would affect temperatures is auto-cpufreq (which has slightly lowered temperatures).

I dont know how well it actually works but I use this: https://github.com/AdnanHodzic/auto-cpufreq

auto-cpufreq (switching between performance- and powersaving mode),

You can also use tools like auto-cpufreq to reduce your cpu frequencies when not in heavy load. auto-cpufreq can be configured a lot to meet your specific needs. auto-cpufreq: https://github.com/AdnanHodzic/auto-cpufreq

Also refer to https://github.com/pop-os/system76-power/issues/153 for setting environment variables and making simple scripts with it.

One example would be, I had problems with running native version of Substance Designer. And it had something to do with always using GPU or setting environment variables(https://github.com/pop-os/system76-power/issues/153). But I wouldn't know what to look for if a random guy on a forum didn't tell me to use it with NVIDIA Graphics.

[Update 2022-02-21] It appears that there are two packages, System76-io-dkms and System76-power. From what I gather only the first is necessary. I'm not sure how to install third-party DKMS modules that are not in the official repos. The official Void documentation on this topic is sparse, is there somewhere I can look this up?

Initially it only worked with Intel CPUs but it seems it supports AMD APUs now according to this Github issue https://github.com/pop-os/system76-power/issues/73

system76-power

The performance modes are going to affect how much power the system is using (and thus how much heat it's generating), not the fan curves directly. Those profiles are defined in the system76-power application, source code here: https://github.com/pop-os/system76-power/blob/master/src/daemon/profiles.rs

The script uses udev rules that are run at specific kernel events. It creates one rule for when the Laptop switches to battery power and another for when the Laptop switches to wall power. Both rules run system76-power while providing one of the available power profiles as an argument. I went with battery and balanced respectively.
