nixos-config VS System76 Power Management

Here’s Mitchell Hashimoto (founder of HashiCorp) setup config.

https://github.com/mitchellh/nixos-config

In my case, I started by installing the NixOS using the Gnome Installer on VmWare fusion, and then modified it using the example config from mitchellh as a guide. Actually entering the configuration yourself definitely helps with learning.

I have a NixOS dev environment in a VM which I built based on https://github.com/mitchellh/nixos-config. Similar to that setup, I use Flakes for my main configuration, and use home-manager to install + configure dev tools that I want available across multiple projects

Yes, maybe not as easily. Check my setup https://github.com/kohlerm/nixos-config which I forked from https://github.com/mitchellh/nixos-config a while ago

Hi, if u can not get a linux pc - then have a look on the following thing (nixos). https://github.com/mitchellh/nixos-config

I'm developing mostly using console applications like vim so I don't need GUI apps for what I'm doing and this made me wonder if it's not better to simply spin a Linux VM inside my macOS to do my development. Something like this: https://github.com/mitchellh/nixos-config (this guy is one of the founders of Hashicorp)

One of the most popular NixOS configs on GitHub does this https://github.com/mitchellh/nixos-config

The README describes the experience, though the author takes the approach of using the VM mainly for terminal-based stuff.

This post focused solely on the Nix package manager and Nix packages - for anyone that uses MacOS but is interesting in trying NixOS (or using it within a VM in MacOS), I definitely recommend Mitchell Hashimoto's NixOS repo: https://github.com/mitchellh/nixos-config

Honestly, doing that may be easier and a better option than using Nix packages in MacOS.

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.
