+
+## DPMS
+
+Display Power Management Signaling controls power saving features on displays.
+
+Query current settings:
+
+    xset q
+
+Turn DPMS on/off:
+
+    xset -dpms # screen will not timeout
+    xset dpms
+
+Force screen poweroff:
+
+    xset dpms force off
+    xset dpms force standby
+    xset dpms force suspend
+
+Off/standby/suspend are different power-off modes. They have trade-offs in power
+consumption vs. time to restart.
