Login Manager

In this module you can configure the " "various aspects of the KDE Login Manager. This includes " "the look and feel as well as the users that can be " "selected for login. Note that you can only make changes " "if you run the module with superuser rights. If you have not started the KDE " "Control Center with superuser rights (which is absolutely the right thing to " "do, by the way), click on the Modify button to acquire " "superuser rights. You will be asked for the superuser password." "

Appearance

On this tab page, you can configure how " "the Login Manager should look, which language it should use, and which " "GUI style it should use. The language settings made here have no influence on " "the user's language settings." "

Font

Here you can choose the fonts that the Login Manager should use " "for various purposes like greetings and user names. " "

Background

If you want to set a special background for the login " "screen, this is where to do it." "

Shutdown

Here you can specify who is allowed to shutdown/reboot the machine " "and whether a boot manager should be used." "

Users

On this tab page, you can select which users the Login Manager " "will offer you for logging in." "

Convenience

Here you can specify a user to be logged in automatically, " "users not needing to provide a password to log in, and other convenience features.
