Colloid-Catppuccin theme loaded via ~/.config/gtk-4.0/gtk.css at
PRIORITY_USER (800) was overriding moongreet's PRIORITY_APPLICATION (600),
causing avatar to lose its circular border-radius.
- Use STYLE_PROVIDER_PRIORITY_USER for app CSS provider
- Replace border-radius: 50% with 9999px (GTK4 CSS percentage quirk)
- Include missed Cargo.lock and PKGBUILD updates from v0.6.0
Fingerprint auth was missing because moongreet rejected multi-stage
auth_message sequences from greetd. With pam_fprintd.so in the PAM
stack, greetd sends non-secret prompts for fingerprint and secret
prompts for password — moongreet now handles both in a loop.
- Replace single-pass auth with multi-stage auth_message loop
- fprintd D-Bus probe (gio::DBusProxy) for UI feedback only
- Fingerprint label shown when device available and fingers enrolled
- 60s socket timeout when fingerprint available (pam_fprintd scan time)
- Config option: [appearance] fingerprint-enabled (default: true)
- Fix: password entry focus loss after auth error (grab_focus while
widget was insensitive — now re-enable before grab_focus)
Complete rewrite of the greetd greeter from Python/PyGObject to Rust/gtk4-rs
for consistency with moonset, single binary without Python runtime, and
improved security through Rust memory safety.
Modules: main, greeter, ipc, config, i18n, users, sessions, power
86 unit tests covering all modules including login_worker IPC flow.
Security hardening: shell-word splitting for exec_cmd, absolute path
validation for session binaries, session-name sanitization, absolute
loginctl path, atomic IPC writes.
