You could write a script / set of scripts that issue the appropriate xrandr commands to enable / disable that monitor output. For example, I have the following bash aliases on my laptop to enable / disable the VGA output: alias extendvga='xrandr --output VGA1 --auto --right-of eDP1; xrandr --output eDP1 --primary' alias retractvga='xrandr --output VGA1 --off' --Sean
