    NUC6i7KYK black screen when booting into kubuntu 16.04

      I just installed Kubuntu 16.04. When booting, the screen stays black forever and after some time the monitor (AOC U3277PQU) says "No Signal".

       

      After disabling graphical boot, I can say that the NUC's HDMI output dies after starting the X server. The ASCII boot messages up to that point do

      appear. With standard graphical boot, the display never shows anything at all. Nothing to see about it in any log

      (/var/log/Xorg.0.log, $HOME/.xsession-errors).

       

      The only fix I found:

      If I disconnect and reconnect the HDMI cable, it takes a moment and the display works. I Have to do that after the X session started (with non-graphical boot)

       

      Some data:

      - Upgraded BIOS from 0033 to 0035, no change

      - The same works with a different very cheap monitor

      - I replaced the kubuntu kernel by self-compiled unpatched Linux 4.6.2, no change

      - The BIOS is set to HDMI output only

      - The monitor is set to HDMI input only
