I keep my Laptop PC always connected to my HDMI tv. When I am watching a movie on the tv, i use the command
xrandr --output LVDS1 --off to turn my laptop screen Off (it is annoying to see the movie on a small screen beside the Tv).
So, with this command, the Laptop Screen is Off, and everything is displayed in the TV
The question is: How do i Turn my Laptop Screen BACK ON? Right now, i have to remove the HDMI cable, then it turns on. I Would like to do it via Command Line. How?????
