I hope anyone can help me, I'm posting this as a new question because all solutions point to installing linux kernel 4.3, but I'm already on 4.4 from the start.

I have tried to install the firmware drivers from the intel website, the GUC 6.1 and the DMC 1.23 (the contents from dmc 1.26 didn't match the installation instructions). This all seem to end without errors

Here is some info from the hardware

*-display UNCLAIMED

I finally got to solve this after days. First, I had the problem that the HDMI cable was not recognized. There recommendations about kernels so upgraded and downgraded several versions but the problem persisted.

I started seeing the drivers as you and installed the Intel Updater Tool. This installed and apparently updated the driver but I had failed to read complete instructions that tell you to add a new source to repository, update and upgrade.

After this, I run the updater tool, but holy, same result: display UNCLAIMED.

Finally I remembered I had altered a line of the GRUB to nomodoset, so I deleted it, rebooted, and voila, the driver was loaded and HDMI recognized.

  • I'm marking your answer as solved (out of ALL the answers). My problems magically disappeared when i used another OS on another machine =) ) – oneindelijk May 7 '18 at 14:48
