Disable the internal keyboard of laptop automatically when using external keyboard(s).
Writting it in Rust just for fun. A shell script is equivalent.
Run it in a systemd service to enable it automatically.
This tool is only for Linux laptop, and it is really simple so I'm not interested in accomplishing it as it already works.
- libevdev-dev
- libudev-dev
Use udev to
- collect the information of input devices in
/dev/input/eventX - monitor the
udevevents, or to say the events of inserting and removing a device
Invoke ioctl with signal EVIOCGRAB to disable the internal keyboard. And use evdev to achieve that for convenience(I don't want to write unsafe code).
