Unable to change power profile in the battery gui

[garare992]

Nothing happens when i press battery or high performance

[garare992]

I didn't have this issue when I was using the pop-os alpha iso.

Can you share your NixOS configuration, especially surrounding power settings like power-profiles-daemon or system76-power?

{
  config,
  lib,
  pkgs,
  ...
}:
{
  services.desktopManager.cosmic.enable = true;
  services.displayManager.cosmic-greeter.enable = true;
  hardware.system76.enableAll = true;
  services.power-profiles-daemon.enable = false;
}

I turned off power-profiles-daemon because I read that it conflicts with system76-power.

[lilyinstarlight]

hardware.system76.enableAll = true;

I don't think you're supposed to do that on non-system76 hardware. I'll try to take a look tomorrow though

I have a same issue when I use system76-power instead of ppd.
It requires root privilege to change power profile. Therefore, it can't be changed from applet.

Can you systemctl status system76-power to ensure that it is running?

Also can you start cosmic-settings from terminal and share terminal output after trying to set a power profile from there?

Thanks!

I can't tell very well because screenshots are hard to read on mobile (well and also in general), but it looks like you don't actually have a working power profiles daemon?

Can you system76-power profile from command line and copy/paste output?

the System76 power daemon is working in that screenshot.

Ugh, digging in to this it looks like sys76-power is very out of date and packaged wrong in nixpkgs...

Given you aren't on system76 hardware, I'd probably still recommend going with power-profiles-daemon. But otherwise someone might need to fix this in nixpkgs first (if it wasn't packaged so wrong I could just overlay it here to update, but it's erroneously in kernelPackages for some awful and clearly incorrect reason.....)

Oh, I see. I hope you report it to whoever it concerns so it gets fixed. But yeah, l'll switch to power-profiles-daemon.

Since I'm not using system76 hardware, can I do without hardware.system76.enableAll = true;? Or does cosmic depend on it?

Yeah that option is intended for system76 hardware and is not associated with cosmic at all

[lilyinstarlight]

It looks like there is a PR to fix it upstream that's not been touched (typical nixpkgs experience...): NixOS/nixpkgs#342921

Hi, I'm the author of the PR. The system76-power package needs an update to work with cosmic. I've been maintaining an out-of-tree patch for it that I will try to get in as soon as that PR merges. However, I believe system76-power is hardware specific and non-system76 machines should use power-profiles-daemon.

[lilyinstarlight]

Thank you for that @sjmonson! You might find luck posting your PR to the nixpkgs review requests Matrix room or on one of the PR review requests Discourse threads

(Also, apologies nixpkgs contributions are so difficult to get reviewed and merged, and that it's so luck-based... (I've really been losing faith in nixpkgs as an upstream, despite previously being an active contributor, subsystem maintainer, and committer for years...))

[sjmonson]

Thanks @lilyinstarlight I'll give that a go! And yeah, as someone who has contributed to other distributions before, I've found the nixpkgs experience quite lacking.
