GDM: how to change theme

[8-me-n]

Hi,

I'm running ubuntu-gnome 13.04 and i can't figure out how to change the theme and wallpaper for GDM.

thank you,

The package needed to change the theme is gnome-tweak-tool, search for tweak tool.
Right mouse click on any desired image to get an option to set it as the desktop background.
I'm glad you asked this, the feature was not working last time i tried a few months ago but it is now.:D

Changing background from gnome-tweak-tool changes only lock screen background. It does not change the initial login screen background. Is there any way to change the initial login screen background?
