Change Background of Login Screen in uBuntu 12.10

Annoyed and bored with the same standard login screen? Here's how to turn it into one of your own images.

1. Open the Terminal

2. Type sudo -i and enter your password.

3. Type xhost +SI:localuser:lightdm

4. Type sudo su lightdm -s /bin/bash

5. Type gsettings set com.canonical.unity-greeter draw-user-backgrounds 'false'

6. Type (replacing imagelocation.jpg with the location of your chosen image) gsettings set com.canonical.unity-greeter background '/imagelocation.jpg'

7. Type gsettings set com.canonical.unity-greeter draw-grid 'false' to remove the dotted lines uBuntu that appear.

Restart uBuntu and you should be good to go!
