114 "Control Center with superuser rights (which is absolutely the right thing to "
115 "do, by the way), click on the <em>Modify</em> button to acquire "
116 "superuser rights. You will be asked for the superuser password."
117 "<h2>General</h2> On this tab page, you can configure parts of "
118 "the Login Manager's look, and which language it should use. "
119 "The language settings made here have no influence on "
120 "the user's language settings."
121 "<h2>Dialog</h2>Here you can configure the look of the \"classical\" "
122 "dialog based mode if you have chosen to use it. "
123 "<h2>Background</h2>If you want to set a special background for the dialog based "
124 "login screen, this is where to do it."
125 "<h2>Themes</h2> Here you can specify a theme to be used by the Login Manager."
126 "<h2>Shutdown</h2> Here you can specify who is allowed to shutdown/reboot the machine "
127 "and whether a boot manager should be used."
128 "<h2>Users</h2>On this tab page, you can select which users the Login Manager "
129 "will offer you for logging in."
130 "<h2>Convenience</h2> Here you can specify a user to be logged in automatically, "
131 "users not needing to provide a password to log in, and other convenience features.<br/>"
