Turn off monitor from Linux CLI

March 21, 2012 by Noah
I keep looking up this information and then losing track of it, so I'm posting it here for my own reference.

This command will turn off the monitor on a Linux box from the command line (sorta like what happens when you have your power saving options configured to do this automatically after a length of time):

xset dpms force off
The monitor turns off until you hit a keyboard button or move the mouse. With this info you could set up a keyboard shortcut to run this command and have something like a "lock screen button" on your netbook, to turn off the display on command and conserve battery life for a little bit longer than usual.

For a "lock screen button" that also locks the screen in addition to turning it off, a pair of commands like this may be handy:

xset dpms force off; xscreensaver-command --lock

Hi I am trying to turn off 4 monitors at a time using the above command. It so happens that it turns off the 3 monitors except for 1 which displays RGB screensaver . Can you suggest a way out to turn off all the 4 monitors .

Thanks a ton !! Very Helpful. You could write a shell script as follows and run it from the Desktop like a batch file in windows

Create a new file with text editor

#!/bin/bash
xset dpms force off

Save file as .sh extension Chmod 755 to set permissions

Thank you. I created a Desktop Icon with that command to put my monitor to sleep.
