NixOS Configuration

my personal nixos config utilizing flakes & home-manager

features

• hosts: main-desktop (gaming/dev) and server (self-hosted services)
• WM/DE: hyprland by default, with mango and niri boot specialisations
• theme: rose pine via stylix
• secrets: managed via agenix
• formatting: alejandra
• monitoring: prometheus, alertmanager, grafana, loki, and alloy validation through flake checks

file structure

• flake.nix: main flake.
• hosts/: machine-specific configs and hardware settings.
• users/: user-specific entrypoints.
• secrets/: encrypted agenix keys.
• modules/:
  • system/: system-wide modules (core, hardware, users).
  • home/: home manager config (shell, dev, programs, window managers).
  • desktops/: base configurations for hyprland, mango and niri.
  • stylix.nix: themeing config.

installation

1. clone:

   git clone https://github.com/vMohammad24/nixos-config.git ~/nixos-config
   cd ~/nixos-config

2. apply your hardware-configuration.nix:

alot of stuff in this project is hardware-specfic, so you should generate a hardware-configuration.nix using the nixos-generate tool and place it in the hosts/(main-desktop/server) directory of the project.

review modules/system/hardware.nix and each enabled compositor's monitor file. make sure the host SSH key is authorized to decrypt its agenix secrets.

3. build and switch:

   sudo nixos-rebuild switch --flake .#main-desktop
   sudo nixos-rebuild switch --flake .#server

The mango and niri boot specialisations are included in the main desktop generation.

validation

Run these commands from the repository root before switching:

nix fmt
nix flake check
