The Users panel only shows the "Fingerprint Login" row when it can load
GDM's org.gnome.login-screen schema (panels/system/users/cc-user-page.c,
update_fingerprint_row_state); without it the row is hidden before
fprintd is consulted at all. The schema ships in the gdm package under
share/gsettings-schemas/, which the gnome-control-center wrapper did not
carry. GNOME Shell's own wrapper has it, but that does not help:
org.gnome.Settings is DBusActivatable, so the Shell starts it through
D-Bus activation and it runs as a dbus-:1.x-org.gnome.Settings@N.service
under the user manager, with the manager's environment rather than the
Shell's. So the row never appeared on NixOS even with
services.fprintd.enable and a supported reader.
Add gdm to buildInputs so the wrapper picks up its schema directory, as
is already done for the gtk3 and mutter schemas.

Other Project Repositories
The sources of all official Nix-related projects are in the NixOS organization on GitHub. Here are some of the main ones:
- Nix - the purely functional package manager
- NixOps - the tool to remotely deploy NixOS machines
- nixos-hardware - NixOS profiles to optimize settings for different hardware
- Nix RFCs - the formal process for making substantial changes to the community
- NixOS homepage - the NixOS.org website
- hydra - our continuous integration system
- NixOS Branding - NixOS branding
Continuous Integration and Distribution
Nixpkgs and NixOS are built and tested by our continuous integration system, Hydra.
- Continuous package builds for unstable/master
- Continuous package builds for the NixOS 26.05 release
- Tests for unstable/master
- Tests for the NixOS 26.05 release
Artifacts successfully built with Hydra are published to cache at https://cache.nixos.org/. When successful build and test criteria are met, the Nixpkgs expressions are distributed via Nix channels.
Contributing
Nixpkgs is among the most active projects on GitHub. While thousands of open issues and pull requests might seem like a lot at first, it helps to consider it in the context of the scope of the project. Nixpkgs describes how to build tens of thousands of pieces of software and implements a Linux distribution. The GitHub Insights page gives a sense of the project activity.
Community contributions are always welcome through GitHub Issues and Pull Requests.

Donations
The infrastructure for NixOS and related projects is maintained by a nonprofit organization, the NixOS Foundation. To ensure the continuity and expansion of the NixOS infrastructure, we are looking for donations to our organization.
