Custom Shortcut for switching off the display

Question

I want to add a Custom Shortcut (Keyboard → Custom Shortcuts → Add) for turning off the display but to do that, what 'Command' should I should use?

I want to set a button to switch off the display and switch on.

Answer 1

$ xset dpms force off

Screen wakes up after moving the mouse or pressing a key.

Manually turn off monitor

Answer 2

open your terminal and type as

sudo apt-get install python-xlib

after installing it ,type as

gedit monitoroff.sh

and paste the following code

#!/usr/bin/python

import time
import subprocess
from Xlib import X
from Xlib.display import Display

display = Display(':0')
root = display.screen().root
root.grab_pointer(True,
        X.ButtonPressMask | X.ButtonReleaseMask | X.PointerMotionMask,
        X.GrabModeAsync, X.GrabModeAsync, 0, 0, X.CurrentTime)
root.grab_keyboard(True,
        X.GrabModeAsync, X.GrabModeAsync, X.CurrentTime)

subprocess.call('xset dpms force off'.split())
p = subprocess.Popen('gnome-screensaver-command -i'.split())
time.sleep(1)

while True:
    print display.next_event()
    p.terminate()
    break

Then type as

chmod +x monitoroff.sh

Then open your unity dash and type as keyboard and open it.

after opening it click at + symbol to add it.

Then in the name field type name as monitor off & at command field type path of the script. In my case it is ~/monitoroff.sh

after adding it click ok.

then select it with mouse and then press your hotkey , in my case it is F11.

to power on your mouse again click your mouse or press escape key .

Then
