How to disable X11 blackout?

sudo systemctl set-default multi-user.target   // disable graphical ui
sudo systemctl set-default graphical.target    // enable graphical ui

Sorry,  I make no sense.
Going to black just because linux going to sleep..
Moving your mouse or typing any key can wake it up.
Or you can setup sleep time in setting.
