Reproducing on a fresh machine
1. Install NixOS
Boot the NixOS ISO, partition, and install as normal. During install, choose KDE Plasma if prompted.
2. Enable flakes temporarily
nix-shell -p git --command "bash"
# or just proceed if git is already available
3. Clone this repo
git clone <repo-url> ~/nixos-config
cd ~/nixos-config
4. Provide the hardware config
hardware-configuration.nix is machine-specific and not tracked in git. Copy the one generated by the NixOS installer:
cp /etc/nixos/hardware-configuration.nix ~/nixos-config/hosts/nixos/hardware-configuration.nix
5. Apply the configuration
sudo nixos-rebuild switch --flake ~/nixos-config#nixos
6. Lock the flake inputs
nix flake update
Commit the resulting flake.lock so future rebuilds use the exact same package versions.
Daily usage
| Task | Command |
|---|---|
| Apply system + home changes | sudo nixos-rebuild switch --flake ~/nixos-config#nixos |
| Update all inputs | nix flake update |
| Roll back last switch | sudo nixos-rebuild switch --rollback |
| Search packages | nix search nixpkgs <name> |
Adding packages
- System-wide (available to all users):
hosts/nixos/configuration.nix→environment.systemPackages - User-level (home-manager managed):
home/duynguyen/default.nix→home.packages - Per-user via NixOS:
hosts/nixos/configuration.nix→users.users.duynguyen.packages
Vietnamese input setup (fcitx5)
After first build:
- Open fcitx5-configtool
- Go to the Input Method tab → add Unikey
- Switch between English/Vietnamese with Super+Space
Unikey supports both Telex (default) and VNI — configure in the Unikey settings.
