Binary package hint: gdm

Description: Ubuntu 10.04 LTS
Release: 10.04

When launching System > Administration > Login Screen, the Login Screen Settings window opens, but everything is greyed out. I click on the "Unlock" button, but it is un-responsive.
When I looked at the processes, I found it is the gdmsetup with the id 6532.
So I then opened Terminal and tried launching it both with and without sudo, but I get the same error both times:

I'm able to launch other applications such as Synaptic Package Manager, Update Manager, etc. without any issues.
As of the time I'm writing this, I have also ran all updates and rebooted since.
I've checked and the user I'm using is a sudoer.
