Goal

Provide biometric authentication feedback for greetd-based login setups.

Context

greetd is a modern, minimal, Wayland-first display manager growing in popularity (NixOS, Arch Linux Wayland setups). It decouples the DM from the greeter: any program that implements the greetd IPC protocol can act as a greeter (gtkgreet, tuigreet, wlgreet, etc.). PAM auth via pam_linux_hello.so (EPIC-05) works automatically; this EPIC adds the visual overlay.

Scope

Implement or extend a greetd-compatible greeter that shows biometric auth feedback
Subscribe to D-Bus signals from linux-hello-daemon
Provide a Slint-based greeter (slint-greet) or integrate with an existing greeter (e.g. gtkgreet) via D-Bus overlay
Reuse Slint overlay components from EPIC-10

Dependencies

EPIC-04 (auth daemon)
EPIC-10 (Slint auth overlay — visual component)

Out of scope

SDDM (EPIC-13), GDM (EPIC-14), LightDM (EPIC-19)
greetd session management beyond auth feedback
