Linux Keyboard OSD Notifier

A basic OSD notification and tray indicator that notifies capslock and numlock states

Features

• System consistent design (for KDE)
• Supports theming via system preferences
• Works with user-space permissions
• A tray indicator that shows active states of modifier keys

Why?

Some keyboards have no light for indicating capslock and numlock states (like mine). And there's no way to understand the active state until press the key. And most OEMs won't provide some mini-tools like that for Linux. So I made a OSD Notifier for Linux.

Working Mechanism

The application is hooking modifier keys via X11 to handle state changes (since Wayland doesn't provide a way without requiring root permissions). And using a Wayland window to show OSD.

FAQ

• I am using X11 and the application is not working.

  The application is using Wayland APIs to show OSD window. So application is not supported on your platform.

• I am using Wayland however OSD doesn't shown.

  Please ensure your system is supporting XWayland and ensure a composer setting is not blocking listening modifier key events to prevent data leaks.

  If you are using KDE, you can change the behavior via System Settings > Security & Privacy > Application Permission > Legacy X11 App Support.

  

• The Wayland window is stealing focus/keeping on bottom when I press modifier key, how can I prevent that?

  If you're using KDE, you can import the window rule to fix that. Since Wayland doesn't provide a way to set them, you should use a window rule or accept it as is.
