--- Comment #4 from Jani Nikula <jani.nikula at intel.com> ---
It looks like the external connectors aren't connected to the integrated
graphics, at all. I presume xrandr won't list them either. Sorry, closing. If
you find any evidence to the contrary (like Windows working okay with this)
please reopen.

You might have better luck through the Thunderbolt connector on the thing; I'm
not giving any guarantees though.

Side note, you are missing DMC firmware:

[    2.375361] i915 0000:00:02.0: Direct firmware load for
i915/skl_dmc_ver1.bin failed with error -2
[    2.375410] [drm:i915_firmware_load_error_print [i915]] *ERROR* failed to
load firmware i915/skl_dmc_ver1.bin (0)
