+                is a service that restores the display backlight
+                brightness at early-boot and saves it at shutdown. On
+                disk the backlight brightness is stored in
+                <filename>/var/lib/backlight/</filename>. Note that by
+                default only firmware backlight devices are
+                saved/restored.</para>
