+.SH DPMS
+
+The \-d (\-\-dpms) option was removed from i3lock in version 2.8. There were
+plenty of use-cases that were not properly addressed, and plenty of bugs
+surrounding that feature. While features are not normally removed from i3 and
+its tools, we felt the need to make an exception in this case.
+
+Users who wish to explicitly enable DPMS only when their screen is locked can
+use a wrapper script around i3lock like the following:
+
+.Vb 6
+\& #!/bin/sh
+\& revert() {
+\& xset dpms 0 0 0
+\& }
+\& trap revert SIGHUP SIGINT SIGTERM
+\& xset +dpms dpms 5 5 5
+\& i3lock -n
+\& revert
