Cannot unlock with Swaylock on NixOS

[cloudlena]

Running Hyprland on NixOS, I have a setup for Swaylock to lock the screen after a while. When it gets locked however, I cannot log in anymore. It just keeps telling me that the password is wrong. The exact same setup works using Sway.

Am I doing something wrong or is that a bug in how the NixOS setup is connected to PAM? Might be connected to swaywm/swaylock#290.

Tagging @fufexan because it may be connected to Nix.

You need to add security.pam.services.swaylock = { }; to your system config.

See: NixOS/nixpkgs#143365

Indeed, that fixed it. Many thanks, @donovanglover!
