I am only staying with windows because of a feature that so far I cannot find that linux has. i am trying to find a way to blank 2 specific monitors and leave my primary monitor on. Preferably with a bash or with keyboard. This will be used when watching a video on the primary screen and not needed the other 2 monitors. IE the setup I have in windows is a program that allows me to "blank" any monitors i want with a keyboard shortcut. I have a nvidia gfx card.

I would tun xrandr to find out how my outputs were named and then, assuming my three montiors are called DVI-I-2, DVI-I-2 and DVI-I-3, use the following to leave DVI-I-1 on while toggling 2 and 3:
xrandr --output DVI-I-2 --off --output DVI-I-3 --off
xrandr --output DVI-I-2 --auto --output DVI-I-3 --auto
How you bind that into your workflow is up to you.
I haven't tested chaining multiple --output arguments (I only have two monitors), so you may need to split each command in two. And if --auto doesn't work, setting --mode explicitly should. man xrandr will show you the light.

Will it be possible to reverse the command to on or would I have to manually hit the power button to turn them back on? Oct 13, 2013 at 21:52

1The second line is the one that turns them back on (or should do - as I go onto say, you might need to explicitly specify a mode)– Oli ♦Oct 13, 2013 at 22:00
