Caveats

• NOTE: I had to reboot after doing this to eliminate display artifacts.
• Also, the dock doesn't appear to support using both of the displayport ports simultaneously :'(
• And MST (https://en.wikipedia.org/wiki/DisplayPort#Multi-Stream_Transport_(MST) ) doesn't seem to work on this dock, so you can't daisy chain monitors.

TLDR

1. download driver from http://www.displaylink.com/downloads/ubuntu (redirects to https://www.synaptics.com/products/displaylink-graphics/downloads/ubuntu)
