I was trying to test extended mode on CNL but I wasn't able to do it, 

running xrandr --output DP-1 --left-of eDP-1  I could not get that first
display shows next to the other one, they are always cloned.

Current monitors connected :
1xeDP, 1xHDMI and 1xType-C to DP

Steps to reproduce:
1.Run Ubuntu in Graphic mode, open a terminal and write the command: 
  xrandr --output DP-1 --left-of eDP-1
2. See that extended mode is not working, all monitors still cloned.
