How to activate numlock on by default in openSUSE with Xfce
Problem:
You have openSUSE with Xfce desktop environment installed and you want to turn numlock on by default so that you can use the number-pad on your keyboard at the login screen and after logging-in to Xfce desktop. This should have been the default behavior but sadly it’s not! Anyway, it’s an easy problem to fix. This solution is written for openSUSE but it should work on almost all GNU/Linux distributions with Xfce desktop environment and LightDM display manager.
