    Intel NUC Kit NUC6i7KYK HDMI sleeps but won't awake Ubuntu 16.04; Displayport works fine

    DazWilkin

      Have 2 monitors connected DisplayPort (via mini connector) and HDMI.

       

      The DisplayPort monitor sleeps and wakes correctly.


      The HDMI monitor once it sleeps, won't wake. The only solution for me is to pull the HDMI cable form the back of the Skull and reconnect it.

       

      I'm runnng the latest BIOS on the Skull.

       

      Any help would be appreciated.
