How do I get LightDM to allow language selection at login?

view story

http://askubuntu.com – On my login screen, I don't see the option for changing the language which will be displayed when I login. After some searching, I found that I need to use gdm as my graphical login manager, and followed the steps outlined here yet I find that I am unable to select the language at login. As I remember from using Linux Mint (which used gdm), there was a pop-out menu at the bottom of the screen for doing this. Has this feature been removed from Ubuntu or gdm? Is there something I forgot to do? Any help is greatly appreciated. (HowTos)
