--- Comment #49 from Oliver Charles <ollie at ocharles.org.uk> ---
I have a ThinkPad T440p with an Ultra dock and I can also confirm this
behaviour. However, I have managed to successfully get the screen to work
occasionally, but I can't quite determine the steps to get it to successfully
configure. Like others, `xrandr` causes the laptop to freeze and undocking it
resolves it.
