well, this one works!

Two caveats, have to switch DP1-8 and DP1-9, otherwise, I have switched sides.

However, I would like to have a clone. But this seems to be a bit tricky,
I can say same-as, bud not as a conjunction of both DP1-8 and DP1-9. 

Is there any possibility to mirror eDP to both DP1-8 and DP1-9? Or the best
I can get is independent screens? 

On NVIDIA, I had to setup xinerama to have a big single screen. However, with
xinerama, xrandr is inoperational. So no luck here?
