System76 Power Management VS undervolt

See: https://github.com/pop-os/system76-power

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.

Macbook Airs of that era ran Sandy Bridge processors, so, assuming apple didn't factory under volt them, you can usually get away with at least a 100 mV under volt, which would increase all core performance, extend turboboost time, and increase battery life.

it being Debian means you can also easily install the liquorix kernel from the MX control panel, to get some decent gaming focused optimizations. I'd also suggest checking out https://github.com/georgewhewell/undervolt and considering undervolting your laptop, as it's about the only performance hack you can do with older, low powered laptops. It makes a big difference on the chromebooks I was mentioning, lower battery usage, lower temperature, and able to run at full boost speed with no real issues. That, and configuring zram with zstd compression and zram-size=ram can be a real gamechanger on machines with low memory. Also, it might be worth it to just get some more memory, if that's an option, but I couldn't tell you without knowing more about the laptop.

undervolt on linux

With intel you can easily use intel undervolt to extend battery life (I use this on my T580: https://github.com/georgewhewell/undervolt

I dualboot Linux Mint and Windows 10 on my laptop. I already use Throttlestop for undervolting on Windows, and wish to do the same on Linux. So far the only ways to undervolt an Intel CPU in Linux that I have found are 3 similar softwares based on the same project: https://github.com/mihic/linux-intel-undervolt . Out of these 3 the only one I could understand to install was this one: https://github.com/georgewhewell/undervolt . According to the documentation, it should work with my CPU.

Hello all. I'm using a Predator Helios 300 (2020) and was using Throttlestop before switching to Nobara. Stumbled upon this undervolting program on GitHub and just wondering if this is safe to use given that Nobara is using a custom kernel? My laptop tends to go around 95ish in temps while gaming and I know that's normal for a gaming laptop, I just want to lower it a bit.

I used undervolt (https://github.com/georgewhewell/undervolt). Not sure about intel-undervolt, didn't try it.
