Turn off a screen in terminal

Question

Hoy.

I have a multi monitor setup and when watching movies I'd like to turn off or black out the other screens.

I've tried

xset -display :0 dpms force off

and

xset -display :0.0 dpms force off

however it turns all the screens off. echo $DISPLAY prints :0 .

Does anyone know some magic?

I just used that linked answer myself but assigned keyboard shortcuts +B to blank the screen and +U to unblank the screen. +1 to your great question! — WinEunuuchs2Unix, Oct 30 '16 at 19:07

I don't know how did you setup your monitors but you can use xrandr to turn off an screen like this:

xrandr --output VGA1 --off

which turns off the monitor connected to VGA1. you can change VGA1 to eDP, HDMI, etc.

It's functional but possibly that you cannot make your monitor back – wsdzbm Dec 08 '21 at 17:45
