Today, one of my friends gave me this tip, so sharing with my friends…
To turn off laptop display you can execute below command
[root@node] sleep 1; xset dpms force off
Above would turn off the laptop display so that you can save power and keep jobs running in the bg.
Any key press or mouse events can bring back the display
Also query ‘xset’ options via
[terminal]
[root@node]$ xset -q
