Thanks for your reply.
This program does just what xrandr does.
I didn't find a way to separate screens. It seems to define by default a virtual workspace, and let you just put both screens in this virtual workspace.
The command at the bottom of this mail does just that.

I want that the monitors will not show the same workspace. Both should show different desktops.
It is like running xorg twice.

Try arandr.
I have the same setup and arandr does the job perfectly. Moreover, it
saves the settings as script that you can call upon boot.
