How can I dim only select screens of my multiple-monitor linux system?
I have 5 monitors connected to my computer 4 *15 inch and one 27 inch.
sometimes i want to use only the main screen (27) and have the rest black or in power save
How can i do this? I'm running ubuntu linux 13.10 with kde.
To blackout all screens I use
xset dpms force off but this will be undone as soon as i touch the mouse or keyboard.
