Help text

Turn LEDs on when there is input (/dev/input/event*) activity and turn them back off again after there has been no activity for 5 seconds.

This is primarily intended to control LEDs which are a backlight for capacitive touch-buttons, such as e.g. the menu / home / back buttons found on the bottom bezel of many older smartphones and tablets.

This can also be used to turn on the keyboard backlight LED on input events and turn the keyboard backlight off again when idle.

When build as a module this driver will be called ledtrig-input-events.
