+Subject: power: Add a watchdog to keep X's builtin screen saver disabled
+
+X's builtin screen saver may activate DPMS. Since we want to activate
+DPMS ourselves according to our own policy we must make sure that X's
+screen saver remains disabled.
+
+This code is a copy of the original found in gs-watcher-x11.c from
+gnome-screensaver which stopped being used in GNOME 3.6.
