Right. Then you turn it back on with

$ xrandr --output LVDS1 --auto

I would just map those two commands to some convenient shortcuts. A
keyboard shortcut is just as fast as wiggling the mouse, and that way
you can just turn the screen on/off when you want it to be on/off. It's
not exactly what you asked for, but it's a fallback if you can't find
something that does exactly what you want.
