This isn't new, but I thought I'd report it since it doesn't seem to
get fixed on its own..

That's obviously my XPS13, and it has nothing attached to it, so just
the internal laptop display.
This is all intel, with the Skylake Iris Graphics 540 (i7-6560U).
Everything seems to work fine, it's just the ugly warning.
