Gaussian blur applied at texture load time when `background_blur` is set in moonlock.toml. Refactored wallpaper loading from per-window Picture::for_filename() to shared gdk::Texture pattern (matching moonset/moongreet), avoiding redundant JPEG decoding on multi-monitor.
Moonlock
A secure Wayland lockscreen with GTK4, PAM authentication and fingerprint support. Part of the Moonarch ecosystem.
Features
- ext-session-lock-v1 — Protocol-guaranteed screen locking (compositor keeps screen locked on crash)
- PAM authentication — Uses system PAM stack (
/etc/pam.d/moonlock) - Fingerprint unlock — fprintd D-Bus integration, async init (optional, window appears instantly)
- Multi-monitor — Lockscreen on every monitor, single shared fingerprint listener
- i18n — German and English (auto-detected)
- Faillock warning — UI counter + system pam_faillock
- Panic safety — Panic hook logs but never unlocks
- Password wiping — Zeroize on drop
Requirements
- GTK 4
- gtk4-session-lock (ext-session-lock-v1 support)
- PAM (
/etc/pam.d/moonlock) - Optional: fprintd for fingerprint support
