Highlights

• Multiple NixOS configurations, including laptop and desktop
• Install and partitioning scripts
• Flexible Home Manager with feature flags
• Modular configuration
• Wayland/X11 Setups
• Multiple fully featured desktop environments (KDE Plasma 5/6 and XFCE)
• Live image ISO build with Nvidia drivers, experimental nix features already enabled, unfree software usage, and some nice options for cli and neovim
• Declarative themes with theme module and stylix

References

• Theopn’s and yutkat’s dotfiles - Wezterm settings
• Getchoo’s flake - Nvidia settings

Structure

Here’s an overview of the repo’s file structure:

• flake.nix: Entrypoint for host and home configurations. Also exposes a devshell for boostrapping the system (nix develop or nix shell).
• hosts: NixOS Configurations, accessible via nixos-rebuild --flake.
  • common: Shared configurations consumed by the machine-specific ones.
    • global: Configurations that are globally applied to all my machines.
    • optional: Opt-in configurations/feature flags, my machines can use.
    • users: Configurations for each system on the machines
  • ryzennova: Primary PC - 32GB RAM, Ryzen 5600G, RTX 2060 6GB | KDE Plasma 6
  • yoganova: Lenovo Yoga 7i - 8GB RAM, Intel i5 1335U | KDE Plasma 6
  • live-image: ISO configuration | Nvidia drivers included | KDE Plasma 6
• home: My Home-manager configuration, accessible via home-manager --flake
  • Each directory here is a “feature” each HM configuration can toggle, thus customizing each machine with configurations for the specific user
• modules: Custom modules that aren’t available in nixpkgs. Can be NixOS or Home-Manager modules (or both!)
• overlay: Patches and version overrides for some packages. Accessible via nix build.
• pkgs: Custom nix packages defined similarly to nixpkg ones. Also accessible via nix build. You can compose these into your own configuration by using my flake’s overlay, or consume them through NUR.

Installation/Usage
