The gtk greeter ships with a working configuration file but you can optionally run the "LightDM GTK+ Greeter Settings"(lightdm-gtk-greeter-settings) application and customize the greeter in many ways.

Entrance

Entrance display manager

Entrance is a configurable DM designed for the Enlightenment desktop environment which allows selection of multiple themes, icons, and the enabling of virtual keyboards. The default installation offers a wallpaper with randomly displayed icons for each user account, although a fixed icon can be specified and custom icons compiled and added. When multiple Entrance themes are installed it is possible to have a default theme displayed on startup and individual themes that appear for each user as they begin login.
