Lock Key Tray Monitor

A Linux X11 alternative to TrayStatus.
Disclaimer: Independent open-source project, not affiliated with or endorsed by Binary
Fortress Software. Lock-key LED monitoring and synthetic test toggles require an X11 session
(Xkb/XTest); Wayland-native windows restrict cross-client keyboard state synthesis.

FEATURES
• Live Lock Keys & System Counters: polls X11 XkbGetIndicatorState every 150ms for Caps Lock,
Num Lock and Scroll Lock states, supports XTestFakeKeyEvent test toggles, and reads live
/proc/stat CPU%, /proc/meminfo RAM%, and /proc/diskstats per-device KB/s I/O.
• Dynamic System Tray Badges & Floating HUD Overlay: updates QSystemTrayIcon indicators and
provides an Always-on-Top (NETWMSTATEABOVE), draggable mini pill HUD with configurable
opacity, corner docking, and click-to-mute alerts.
• Event History & Audio/OSD Alerts: records timestamped lock-key state changes with CSV export,
floating OSD toast popups, system beep alerts, and block-device filtering.
