Is there any unfinished work?

[GeorgesAlkhouri]

Yes, unfortunately this was merely a quick draft to test the build of tlpui. Also see d4nj1/TLPUI#86 and d4nj1/TLPUI#112.

[Aleksanaa]

Maybe write a simple patch on it and wait for the pr to be merged?

[d4nj1]

The issue is that TLP-UI needs an intrinsic default file on runtime and therefore it won't run properly when just deactivated as suggested in https://github.com/d4nj1/TLPUI/pull/112/files
Maybe the application will start then but it won't show the proper default configs at least for TLP versions 1.3 and onwards. As suggested in d4nj1/TLPUI#86 (comment) I could probably add some fallback for Nix packages but other than that you would have to patch this file yourself before creating the Nix package. I will not accept https://github.com/d4nj1/TLPUI/pull/112/files.

[GeorgesAlkhouri]

so the package know uses the intrinisic defaults provided by the tlp package.
One thing to keep in mind for NixOS users is that if you're using tlp via the NixOS module service.tlp, any changes you make to the /etc/tlp.conf file will be overwritten by NixOS with the values from services.tlp.settings defined in your nix configuration every time you rebuild the system.

Also, there is still an issue with using pkexec for the sudo dialog.

is this still being worked on? i might pick it up over the weekend, but i also understand the inherent flaws of using tlpui, as definitions in nix config will override it. A potential solution would be to have tlpui generate the tlp.conf in /etc/tlp.conf and move the nix module for tlp to use /etc/tlp.d/* dropping a file there instead?

[LordGrimmauld]

I gave this PR an update as well as looked into fixing the inherent flaws of the existing nixos module overriding what tlpui generates, that approach can be found in #305278. Happy to take criticism over there too, i understand i made some changes that need to be considered carefully
