So I got my old laptop conected to the TV though the VGA port (doesn't have HDMI) and this is how I got double imagen cloned, the same in the TV than in the laptop.
I want to see ONLY the TV and turn off the Laptop screen.
But when I put the commands:
xrandr --output (the laptop screen) --off. actually turn off the laptop screen like I want, but a few second later it's turn off the TV too.
Any help 
?

Some laptops use a function key (Fn + Fx) keyboard combo to turn off the laptop screen.

yeah, that was my first idea but Fn keys doesn't work with libreelec in my computer :$
There's an option in Kodi settings for "disable other screens" but this only works if Kodi can see multiple screens. If the hardware defaults to mirrored output with a single screen there's not much we can do in software.
