make USE_LIBWEBSOCKETS=1If target device is incorrect. Use the --dev <PATH> option to specify a device event. List available devices run ls -l /dev/input/by-id/
sudo out/keylogger --dev /dev/input/event7There is a list of options available

Rootless method gives you direct access to your keyboard.
To run rootless, follow these steps:
-
Create a udev rules file (for example, /etc/udev/rules.d/90-keylogger.rules)
echo "SUBSYSTEM==\"input\", OWNER=\"$USER\", MODE=\"0660\"" | sudo tee /etc/udev/rules.d/90-keylogger.rules > /dev/null
-
Reload udev rules
sudo udevadm control --reload-rules sudo udevadm trigger
