--- Comment #4 from Elizabeth <elizabethx.de.la.torre.mena at intel.com> ---
This is still easily reproduce with 4.16.0-rc7-commit617cddf0. Whenever SNB
laptop has DP and VGA connected the video signal will be lost in both monitors.
If i use 

     $ xrandr --output VGA-1 --auto 

I'll get video in the VGA monitor, but if I do 

     $ xrandr --output DP-1 --auto

It will return:

      xrandr: cannot find crtc for output DP-1

If only is used one output at the time, besides the laptop's display (LVDS-1),
it works properly.
