+DPMS
+====
+
+Description
+-----------
+
+This patch interacts with the Display Power Signaling and automatically shuts
+down the monitor after a configurable amount of seconds. The monitor will
+automatically be activated by pressing a key or moving the mouse and the
+password can be entered then.
+
+Notes
+-----
+
+The number of seconds until the screen will be disabled is configured
+in `config.h` via the `monitortime` option.
+
+This patch was written against the `1.4`-tag.
