Scheduled wake from sleep mode / go to sleep mode

[Allen.Lesop]

I'm using my new Pi as a digital calendar for the house, connected to a monitor in my kitchen. It would be ideal if we could schedule it to go into a "sleep mode" where it powers down the monitor when we leave for work and turns back on when we get home.

Any suggestions as to how I could do that? I was looking around on the googles and saw people talking about something called "X" and /etc/kbd/config but those directories didn't come with my NOOBs install?


Thanks everyone.

Does the Monitor have CEC power control?
CEC is a single wire bus on the HDMI cable.
Lots of AV stuff with HDMI now have CEC.

It's an old monitor with DVI connections (I'm using a HDMI to DVI cord)

For anyone looking for something like this (works real well for a display at home you don't want on overnight or whatever)

Code: Select all

vcgencmd display_power 0

will turn it off

Code: Select all

vcgencmd display_power 1

will turn it back on

This will put the monitor into "sleep" mode and wake it back up when needed.


you can use that easily through a cron job.

Yep typed that into a terminal screen, it worked, DVI monitor is off.
er how to turn it on again?
No keyboard or mouse wakeup
