dmesg log: boot with eDP; HDMI hotplugged later
Some dual screen setups are currently broken. All the scanlines below the mouse
cursor are wrong, sometimes containing a shade of gray and others repeating the
image above it. I've seen this in APL and GLK using DSI+HDMI, eDP+HDMI and
DSI+DP. In the DP case, however, the screen goes blank and reports lack of
signal.
