Dual Screens on one device (intel)

I am using ubuntu mate 18.04

I believe it uses lightdm as display manager. I have 2 monitors connected
to the same device (intel hd onboard graphics, with 2 ports, one HDMI, one
VGA).

Because of the nature of the applications I run, I need to have 2 separate
X11 screens. I would need to move the mouse between each, but other than
that they should be independent. I should not be able to move windows
between monitors.

I believe that a setup with one Display, and 2 screens, with one monitor
per screen, would work.

Using the display manager gui app I just get a monitor as extended, and it
is on the same Screen.

   -

   Am I correct that one Display, with 2 screens, with one monitor per
   screen, would do what I want?
   -

   And how would I set it up?

Im following this guide:

http://web.archive.org/web/20130429073111/http://en.gentoo-wiki.com/wiki/X.Org/Dual_Monitors#Single_graphics_card.2C_Multiple_X_screens_with_ZaphodHeads

 Xorg: Independent Mode
<https://unix.stackexchange.com/questions/365796/xorg-independent-mode>

this does not mention zaphodheads
https://download.nvidia.com/XFree86/Linux-x86_64/304.137/README/configmultxscreens.html

it seams what i want is called ZaphodHeads - Multiple Screens with the same
device

however the result i get is 2 blank screens only with the text cursor on
the top left corner

it seams to me this is the problem:
