I found that if you edit the file located in the following directory you can change the way he login screen displays on Ubuntu 14.04.
" /usr/share/lightdm/lightdm.conf.d/50-guest-wrapper.conf "
Enter one the following commands:
sudo gedit /usr/share/lightdm/lightdm.conf.d/50-guest-wrapper.conf
Now add: greeter-setup-script=/usr/bin/numlockx on
If you elevate to a root terminal you can skip "sudo".
Enter you administrator password
Either way it will get you to the same spot.
YOU CANNOT JUST NAVIGATE TO THE FILE AND OPEN UNLESS YOU ARE LOGGED IN AS THE "ROOT USER" WHICH IS NOT RECOMMENDED BECAUSE OF SECURITY ISSUES.
If you want to make it so you have to enter a username and password at the login screen add the following line to that same file as "root":
