1) In gnome-appearance-properties:
[x] Aply this theme to the login screen (displayed/enabled only if the user has admin rights)
2) In gdmsetup:
[x] Apply the following theme to the login screen: [Current | v ]
[x] Use the following custom background: [/path/to/image [ Choose... ]]
3) In gdmsetup or as a separate entry in System > Administration:
[Change look of login screen] --> that button would run $gksu -u gdm dbus-launch gnome-appearance-properties, and add something like a notice or window title to differentiate the dialog from System > Preferences > Appearance)

2) In gdmsetup:
[x] Apply the following theme to the login screen: [Current | v ]
[x] Use the following custom background: [/path/to/image [ Choose... ]]
3) In gdmsetup or as a separate entry in System > Administration: e-properties, and add something like a notice or window title to differentiate the dialog from System > Preferences > Appearance)
[Change look of login screen] --> that button would run $gksu -u gdm dbus-launch gnome-appearanc
