To change the Lightdm background you just need to do the following steps:

1 – Edit the /etc/lightdm/unity-greeter.conf  (use sudo to get root privileges)

2 – Change the background=/usr/share/backgrounds/warty-final-ubuntu.png line putting the location of the new background image.

3 – Save your changes.

4 – Logout and login again.

5 – Be happy.

  5. I don’t know, you can try, but I think that it will not work for slideshow backgrounds.
