Since my monitor takes an awful lot of time to turn back on after being physically turned off, I'm looking for a command or a simple utility to turn off my screen with a shortcut. Setting a black screensaver is not satisfactory; I want the screen to "hibernate" (the same effect I would get by turning off the computer while leaving the screen physically on).
I use Alex Cabal script to turn my two monitors screens off and on and it works very fine for me.
# turn screens off/on
# (ɔ) alex cabal
if [ -f $screenOffLockFile ];
notify-send "Screen on." -i /usr/share/icons/gnome/48x48/devices/display.png
while [ -f $screenOffLockFile ]
xset dpms force off
xset dpms force on
You can go to your distro's settings, and add a shortcut => putting the command - xset dpms force off, then put a hotkey(say F9). That's it, whenever you hit the hotkey, your monitor's screen will turn off
