# Install scripts using Nix to achieve cross-distros
|
|
- This directory is currently WIP.
|
|
- See also [Install scripts | illogical-impulse](https://ii.clsty.link/en/dev/inst-script/)
|
|
- See also [#1061](https://github.com/end-4/dots-hyprland/issues/1061)
|
|
|
|
**NOTE: The sdist/nix is not for NixOS but every distro, using Nix and home-manager.**
|
|
|
|
## plan
|
|
TODO:
|
|
Write a proper `flake.nix` and optionally `home.nix` and other files under `./sdist/nix/iiqs-hm/` to install all dependencies that `./sdist/arch/install-deps.sh` does. (**excluding** the screenlock)
|
|
|
|
TODO:
|
|
In this script, implement the process below:
|
|
1. Warning user about "this script is only experimental and must only use it at your own risks.", and prompt `y/N` (default N) before proceeding.
|
|
2. If nix not installed:
|
|
1. install nix via [NixOS/experimental-nix-installer](https://github.com/NixOS/experimental-nix-installer)
|
|
2. Enable nix for shell
|
|
- Update: Skip this step cuz the nix-installer will handle it automatically e.g. in `/etc/zsh/zshrc`.
|
|
3. Ensure the experimental feature, Nix Flake, is enabled.
|
|
3. cd to `iiqs-hm` and use something like `home-manager switch --flake .#iiqs` to install the dependencies.
|
|
4. Install screen lock using system package manager of the current distro.
|
|
|
|
Note that this script must be idempotent.
|
|
|
|
TODO:
|
|
Write guide for people already use nix, so they can manually grab things from this repo to their own Nix/home-manager configurations to install the dependencies.
|
|
|
|
## Attentions
|
|
### PAM
|
|
On non-NixOS distros, programs using PAM (typically screen locker) will not work if installed via Nix, so user has to use their own distro's package for the screen lock.
|
|
|
|
- One problem is that Debian(-based) distros use modified version of PAM which supports `@include` directive in `/etc/pam.d` config files but the PAM from Nix does not support it, see [this comment](https://github.com/NixOS/nixpkgs/issues/128523#issuecomment-1086106614).
|
|
- Another problem is the location of a suid helper binary that is necessary, see [this comment](https://github.com/end-4/dots-hyprland/issues/1061#issuecomment-3403195230).
|
|
|
|
The problem could be solved by using the system-provided libpam instead.
|
|

|
|
|
|
### NixGL
|
|
On non-NixOS distros, packages installed via home-manager have problem accessing GPU, especially Hyprland because it requires GPU acceleration to launch. `nixGL` should be used to address the problem. Example code in `home.nix`:
|
|
```
|
|
{ config, lib, pkgs, nixgl, ... }:
|
|
{
|
|
nixGL.packages = nixgl.packages;
|
|
nixGL.defaultWrapper = "mesa";
|
|
|
|
# other lines not showed here ...
|
|
|
|
home = {
|
|
packages = with pkgs; [
|
|
cowsay # normal packages that does not need nixGL
|
|
lolcat
|
|
# other lines not showed here ...
|
|
]
|
|
++ [
|
|
(config.lib.nixGL.wrap pkgs.firefox-bin)
|
|
(config.lib.nixGL.wrap pkgs.hyprland)
|
|
# other lines not showed here ...
|
|
];
|
|
# other lines not showed here ...
|
|
};
|
|
}
|
|
```
|
|
|
|
And in `flake.nix`:
|
|
```nix
|
|
{
|
|
inputs = {
|
|
nixpkgs.url = "nixpkgs/nixos-25.05";
|
|
home-manager = {
|
|
url = "github:nix-community/home-manager/release-25.05";
|
|
inputs.nixpkgs.follows = "nixpkgs";
|
|
};
|
|
hyprland = {
|
|
url = "github:hyprwm/Hyprland";
|
|
};
|
|
nixgl.url = "github:nix-community/nixGL";
|
|
};
|
|
outputs = { nixpkgs, home-manager, nixgl, ... }:
|
|
let
|
|
lib = nixpkgs.lib;
|
|
system = "x86_64-linux";
|
|
pkgs = import nixpkgs {
|
|
inherit system;
|
|
overlays = [ nixgl.overlay ];
|
|
};
|
|
in {
|
|
homeConfigurations = {
|
|
mydot = home-manager.lib.homeManagerConfiguration {
|
|
inherit pkgs;
|
|
extraSpecialArgs = { inherit nixgl; };
|
|
modules = [ ./home.nix ];
|
|
};
|
|
};
|
|
};
|
|
}
|
|
```
