I am using a Raspberry Pi to run an information display in an office. I want the display in power save mode when outside of business hours. I was going to use
cron to execute something at the beginning and end of the day, but
xset dpms force off doesn't work.
I have disabled the screen saver (so the display stays on during the day) with the addition of
xset s off,
xset -dpms and
xset s noblank in the
Here are the results from

xset s blank && xset +dpms && xset dpms force off will blank the display, but it doesn't put it in power save mode. After reading a lot of threads, I still can't get the system time correct either (I think that may be a firewall issue)...
