Hello Linux Geeksters. As you may know, LightDM is a lightweight display manager used by default on Lubuntu, Xubuntu and Kubuntu, responsable for the login screen, the management of the X servers and facilitates remote logins via the XDMCP protocol. It is used by default on Xubuntu and Lubuntu, among the *Buntu flavors.
LightDM GTK+ Greeter Settings is an open-source graphical user interface that allows the users to easily change the theme, icons, font, background, clock format, login dialog window position, enable or disable onscreen keyboard and other settings of the LightDM Greeter.
Due to a bug discovered in March, 2014, the LightDM GTK+ Greeter Settings could not be added to the default repositories and so, it is not available by default.
