Update: A new graphical application Login Manager Settings has been released since I wrote this article. It makes it much easier to customize the login screen. I recommend using the app instead of following this guide. Theme And Background There are some apps that let you change the appearance (theme and background) of Gnome’s Login Manager (GDM), or its settings. The ones I know of are complicated to use.
