Linux support for multiple screens
Linux does not yet offer explicit support for the DisplayPort MST hub built into this dock, so multi-screen support is not fully functional under Linux. A single screen works fine and is fully controllable, but multiple screens are handled by a some unconfigurable fallback mode, and appear a single display; they cannot be individually configured in terms of resolution, relative position etc.
On the ThinkPad X240, one way to use two external screens is to attach one to a dock port, and another to the laptop's own mini DisplayPort port.
