I use gnome-display-properties for this or otherwise the following script using xrandr
to activate the use of two screens :

#!/bin/sh

sudo xrandr --output eDP1 --auto --output VGA1 --auto --same-as eDP1
sudo xrandr  --output VGA1 --off 
sudo xrandr --output VGA1 --auto --above eDP1

or 

#!/bin/sh

sudo xrandr --output eDP1 --auto
sudo xrandr --output VGA1 --off

to switch back to just the default one.

Your options may differ.  See the xrandr documention.

You can check /var/log/Xorg.0.log

It should not be necessary.
