Public bug reported:
Turns out that Displayport Multi-Stream Transport has not been
implemented for Skylake, causing blank screen issues (now that hangs
have been fixed..) when plugging external displays to outputs connected
to the MST hub. Disabling DP MST allows at least one of the outputs to
work, if there are several behind the hub.
