If this is checked, KDM will use the settings below for the background. If it is disabled, you have to look after the background yourself. This is done by running some program (possibly xsetroot) in the script specified in the Setup= option in kdmrc (usually Xsetup).
Se sinala esta opción, KDM empregara as opcións en baixo para o fondo. Se non o sinala, terá que encargarse por si do fondo. Isto faise executando algún programa (posibelmente xsetroot) no script especificado en Setup= opción en kdmrc (normalmente Xsetup).
