Numlock activate at startup in login screen

It is very annoying that the numlock is not activated at startup in the login screen GDM, especially when using a password that contains numbers.

Make sure that the universe repository is enabled.

Execute the following commands in a terminal

sudo apt-get install numlockx

sudo gedit /etc/X11/gdm/Init/Default

Add the following lines at the end before the line “exit 0″:

if [ -x /usr/bin/X11/numlockx ]; then
/usr/bin/X11/numlockx on
fi

Put off your numlock and restart X by pressing Ctrl+Alt+Backspace

The numlock should be activated now and every time when you reboot
