Fixing screen not waking up (xorg) on Ubuntu from command line

Sometimes after xubunutu screen is in hibernate mode the screen does not wake up.

Open terminal ALT+CTRL+F1 (tty)

  sleep 5 && xrandr -d :0 --output 'eDP-1' --primary --auto

Then switch fast back to the graphic mode (ALT+CTRL+F7) wait a few seconds for the screen to wake up.

'eDP-1' is the name of your screen

You can see connected screens running
    xrandr -d :0
