GTK4 does not reliably read /etc/xdg/gtk-4.0/settings.ini under greetd
without a settings daemon, falling back to default blue accent instead
of Colloid-Grey-Dark-Catppuccin.
Greeter used hardcoded colors (#1a1a2e, white, #ff6b6b) instead of
GTK theme variables, breaking theme consistency across the ecosystem.
Now uses @theme_bg_color, @theme_fg_color, @error_color etc. —
matching moonlock and moonset.
- Add 30s timeout with SIGKILL to power actions (adapted from moonset)
- Add 500ms minimum login response time against timing enumeration
- Cache GREETD_SOCK in GreeterState at startup
- Add [profile.release] with LTO, codegen-units=1, strip
- Add compressed="true" to GResource CSS/SVG entries
- Add SYNC comments to duplicated blur/background functions
- Add nix dependency for signal handling in power timeout
- Add zeroize dependency, wrap password in Zeroizing<String> from entry extraction
through to login_worker (prevents heap-resident plaintext)
- Add MAX_BLUR_DIMENSION (1920px) downscale before GPU blur to reduce 4K workload
- Wallpaper: use symlink_metadata + is_symlink rejection in greeter.rs and config.rs
- Avatar: add is_file() check, swap lookup order to ~/.face first (consistent with
moonlock/moonset)
- greetd errors: show generic fallback in UI, log raw PAM details at debug level only
- fprintd: validate device path prefix before creating D-Bus proxy
- Locale: cache detected locale via OnceLock (avoid repeated env/file reads)
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)
GskBlurNode samples pixels outside texture bounds as transparent,
causing visible darkening at wallpaper edges. Fix renders the texture
with 3x-sigma padding before blur, then clips back to original size.
Symmetric fix with moonset v0.7.1.
Wallpaper is installed by moonarch to /usr/share/moonarch/wallpaper.jpg.
Embedding a 374K JPEG in the binary was redundant. Without a wallpaper
file, GTK background color (Catppuccin Mocha base) shows through and
wallpaper-only windows on secondary monitors are skipped.
Replace unwrap() calls with match-based error handling that falls back
to eprintln — prevents panic when running outside a systemd session.
Consistent with moonlock's logging init pattern.
Address all findings from quality, performance, and security audits:
- Filter greetd error descriptions consistently (security)
- Re-enable power buttons after failed action (UX bug)
- Narrow TOCTOU window in avatar loading via symlink_metadata (security)
- Allow @ in usernames for LDAP compatibility
- Eliminate unnecessary Vec allocation in passwd parsing
- Remove dead i18n field, annotate retained-for-future struct fields
- Fix if/if→if/else and noisy test output in power.rs
Replace CPU blur (image crate + disk cache + async orchestration) with
GPU blur via GskBlurNode — symmetric with moonlock and moonset.
Removes ~15 transitive dependencies and ~200 lines of caching code.
Gaussian blur applied at texture load time when `background-blur` is
set in the [appearance] section of moongreet.toml. Blur runs once,
result is shared across monitors.
- Rework load_background_texture(): use resources_lookup_data()/from_bytes()
for GResource path (no abort on missing resource), add 50 MB file size limit,
handle non-UTF-8 paths gracefully
- Filter error details to debug level only — warn! logs without internal details
to prevent system info leaking into journal
- Make debug logging opt-in via MOONGREET_DEBUG env var (default: Info)
- Truncate greetd error description in stale-session retry path using
MAX_GREETD_ERROR_LENGTH (matching show_greetd_error())
- Add 3 unit tests for load_background_texture edge cases
Replace env_logger file-based logging with systemd-journal-logger for
consistency with moonlock and native journalctl integration. Add debug-level
logging at all decision points: config loading, user/session detection,
avatar resolution, locale detection, IPC messages, login flow, and
persistence. No credentials are ever logged.
display_name() now returns only the first GECOS subfield (before comma)
instead of the full GECOS string with room numbers and phone extensions.
split_shell_words() returns None for trailing backslashes instead of
silently ignoring them.
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.
