NixOS Configuration

Personal NixOS flake configuration.

Layout

• flake.nix - flake inputs and NixOS configurations
• hosts/ - host-level system configuration
• homes/ - Home Manager user configuration
• modules/nixos/ - reusable NixOS modules
• modules/home/ - reusable Home Manager modules
• modules/shared/ - shared data used by hosts and modules

Hosts

• hosts/thinkpad/default.nix - ThinkPad system configuration
• hosts/thinkpad/hardware-configuration.nix - generated hardware config
• hosts/thinkpad/keyboard.nix - host keyboard selection and built-in keyboard config
• hosts/thinkpad/monitors.nix - host monitor names, fallback rules, and lid support

Host files pass machine-specific data into Home Manager through extraSpecialArgs.

Home

• homes/luka/default.nix - base user Home Manager configuration
• homes/luka/hosts/thinkpad.nix - ThinkPad-specific Home Manager imports

Hyprland

Hyprland is split between system and user configuration:

• modules/nixos/wayland/hyprland.nix enables Hyprland, SDDM, XWayland, and lid policy.
• modules/home/wayland/hyprland.nix configures keybindings, inputs, monitor rules, lid handling, and idle locking.

Keyboard profiles are defined as structured data. Host-specific keyboards live in the host keyboard file. Reusable external keyboards live in modules/shared/keyboards.nix and are selected per host.

Monitor data is host-specific. The ThinkPad monitor file defines eDP-1 as the internal panel, a fallback Hyprland monitor rule, and hasLid = true.

Commands

Build the thinkpad configuration:

sudo nixos-rebuild build --flake .#thinkpad

Switch to it:

sudo nixos-rebuild switch --flake .#thinkpad
