Windows

Generic devices

No additional steps should be required.

If you’re encountering problems, feel free to open an issue.

Xbox controllers

If you want to use the guide button in Mumble, the trigger for the Game bar must be disabled.

When the option is enabled, Windows doesn’t pass the input to applications.

Even XInputGetStateEx() doesn’t detect it!

Linux

Poll-driven engine

Uses a little more processing power, but no additional steps are required.

Event-driven engine

Mumble needs read permissions for /dev/input/event*.

The solution usually consists in adding your user to the input group:

sudo usermod -a -G input user

Please note that this allows any applications running under the same user to read data sent by input devices.

If the solution doesn’t work for you, you could allow all users to read the input:

  sudo chmod a+r /dev/input/event*

Please note that this is only meant to be a temporary solution, because:

• It will most likely only last until the next reboot (at which point devfs is recreated).
• It allows any applications to read the input data, regardless of the user they’re running under!

Wayland

On Wayland, global shortcuts must be forwarded to applications by a central component called compositor. Each desktop environment has its own compositor, so support for global shortcut depends on the destkop environment you are using.

KDE Plasma

KDE has settings to define how keyboard shortcuts are forwarded to other programs. By default, most shortcuts will work. Only individual keys that produce text are not forwarded to Mumble. Check System Settings > Application Permissions > Legacy X11 App Support:

If you want to use a mouse button as a global shortcut, you must enable Listening for mouse buttons which is off by default (available since KDE version 6.1).

macOS

Mumble needs to be granted accessibility permissions.
