http://askubuntu.com – I'm using Ubuntu 11.10 on Desktop but Ubuntu originally was installed on laptop. Numeric keypad on my keyboard was set as mouse moving and mouse button. No matter how I toggle Num lock and change the QWERTY to AZERTY and change back, I can't use numeric keypad probably. (HowTos)
