On Ubuntu Xenial 16.04 LTS using kernels 4.6.6, 4.7.x and 4.8.0 (from: <a href="http://kernel.ubuntu.com/~kernel-ppa/mainline/">http://kernel.ubuntu.com/~kernel-ppa/mainline/</a>) I couldn't manage to get HDMI output to any screen. VGA and the rest on this adapter work fine. I resorted to the stock Xenial kernel (as of writing this) 4.4.0-38-generic and I was able to get HDMI working on a 1680x1050@60Hz panel that I have here. Haven't had the chance to test it with something with higher res yet. I should also note that I have manually installed the skl_guc_ver6_1 i915 firmware. I also tested the FC24 live image (uses 4.5.5 kernel IIRC) and that worked out of the box too. Seeing Jani's earlier answer that there is no proper usb type-c alternate mode support yet, I am not sure exactly what's going on and why some older kernels seem to work.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> <li>You are on the CC list for the bug.</li> </ul> </body> </html>
