+ "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."
+ "<h2>Font</h2>Here you can choose the fonts that the Login Manager should use "
+ "for various purposes like greetings and user names. "
+ "<h2>Background</h2>If you want to set a special background for the login "
+ "screen, this is where to do it."
+ "<h2>Shutdown</h2> Here you can specify who is allowed to shutdown/reboot the machine "
+ "and whether a boot manager should be used."
+ "<h2>Users</h2>On this tab page, you can select which users the Login Manager "
+ "will offer you for logging in."
+ "<h2>Convenience</h2> 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.<br>"
+ "Note, that these settings are security holes by their nature, so use them very carefully."));
