dmesg dump

There are issues with a new dock (model undisclosed for now) when hotplugging a
monitor to it; it isn't detected properly until the display configurator or
xrandr is run.

This happens with current drm-next as well, dmesg dump attached (I'm not sure
from which kernel it is though). The display is attached at ~102s, xrandr is
run at ~109s.
