Hello Linux Geeksters. In this quick guide I will show you how to enable the numlock on Ubuntu 13.10 Saucy Salamander.
If you get issues with the numerical keypad on Ubuntu 13.10, this is how you fix it:
Install the numlockx package:
$ sudo apt-get update
$ sudo apt-get install numlockx
Enable numlock in /etc/lightdm/lightdm.conf.d/50-unity-greeter.conf:
$ sudo sh -c 'echo "greeter-setup-script=/usr/bin/numlockx" on >> /etc/lightdm/lightdm.conf.d/50-unity-greeter.conf'
Restart the computer and everything should run smoothly.
