I want to use Plasma-manager in my system. I have enabled flakes in configurations. Now what to do to use it. The output generated by tool rc2nix can be copied through terminal but when i put that in home.nix , it says that plasma is not available which is true but then how do I use this tool. flake file.
First, you need to pass the plasma-manager input to your home-manager config in some way. I use the NixOS module for home-manager which I declare like this in my flake.nix (if you have a different setup, this might not be necessary or you have to do it in a slightly different way):
<span style="color:#323232;">homeManagerModule = {
</span><span style="color:#323232;"> imports = [home-manager.nixosModules.home-manager];
</span><span style="color:#323232;"> home-manager.users.myusername = import ./home.nix;
</span><span style="color:#323232;"> # This will give us access to the inputs in the home-manager config
</span><span style="color:#323232;"> home-manager.extraSpecialArgs = {inherit inputs};
</span><span style="color:#323232;">};
</span>
Now the home-manager config (in my case home.nix) can look like this:
You probably forgot to import the plasma-manager module into home-manager. If you want to have a cleaner setup, I’d also recommend against just copying the complete output of rc2nix into your config since it tends to contain a lot of unnecessary stuff. What I usually do is:
Store the current config in a file, i.e. rc2nix > old-config.nix
Make whatever changes I want in Plasma in the graphical settings app
Store the updated config in a new file, i.e. rc2nix > new-config.nix
Get the difference, i.e. diff old-config.nix new-config.nix and add what I want to my actual plasma-manager config.
This of course only works if you’re starting from a relatively unmodified installation of KDE, but in that case it’s worth the effort imo.

Now don’t know what to do. I got your latter advice regarding diff but first I need to make this work. I am on unstable nixos version. and
The problem seems to be that home.stateVersion is not set because you commented out both the declaration in flake.nix as well as the line that imports home.nix. It’s a bit difficult to see whether the config is otherwise fine since there is a lot of visual clutter due to all the commented-out lines.
