Examples (Nix)

@myxogastria0808/tadaima includes four example greeters. On non-NixOS distributions with Nix, you build them directly from the remote flake with nix build and configure greetd manually.

Available examples

Package	Description
minimal	No wallpaper, no styling, no CSS
simple	No wallpaper, Catppuccin Mocha styling
image	Static image wallpaper + Catppuccin Mocha
movie	Video wallpaper + GStreamer + Catppuccin Mocha

Setup

1. Build and pin the greeter path

Build the greeter and create a symlink to prevent nix-collect-garbage from removing it:

sudo nix build github:Myxogastria0808/tadaima#movie --out-link /etc/greetd/greeter-link

Replace #movie with #minimal, #simple, or #image.

2. Configure greetd

Edit /etc/greetd/config.toml:

[terminal]
vt = 1

[default_session]
command = "dbus-run-session cage -s -d -- /etc/greetd/greeter-link/bin/greeter"
user = "greeter"

3. Setting a wallpaper (image / movie only)

If you chose minimal or simple, skip this step — they don’t use a wallpaper.

The image example expects /var/cache/tadaima/wallpaper.png. The movie example expects /var/cache/tadaima/wallpaper.mp4.

sudo cp /path/to/wallpaper.png /var/cache/tadaima/wallpaper.png
sudo chown greeter:greeter /var/cache/tadaima/wallpaper.png

4. Create cache directory and enable greetd

sudo mkdir -p /var/cache/tadaima
sudo chown greeter:greeter /var/cache/tadaima
sudo systemctl enable greetd

Reboot and you should see the example greeter on the login screen.
