+    <title>Description</title>
+
+    <para><filename>systemd-backlight@.service</filename> 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/systemd/backlight/</filename>. During
+    loading, if the udev property <option>ID_BACKLIGHT_CLAMP</option> is
+    not set to false, the brightness is clamped to a value of at
+    least 1 or 5% of maximum brightness, whichever is greater. This
+    restriction will be removed when the kernel allows user space to
+    reliably set a brightness value which does not turn off the
+    display.</para>
