Just joined this forum and thread because I got my USB 3.0 docking station from Dell a week ago, unfortunately not knowing about the deliberate choice of having it incompatible with Linux. I do need it for work, I am a researcher at Emory university and - given that everything has been said already - I would like to express and emphasize the need of DisplayLink programmers to come up with drivers as soon as possible. I will keep my device hoping that the solution will (really) be available by the 3rd quarter of this year.
Then finally this Wiki article will contain some good news:
https://en.wikipedia.org/wiki/DisplayLink#cite_note-29
I would like to encourage other costumers to keep on expressing their interest for having DisplayLink hardware drivers for Linux and also their concern about the company's Linux adverse policy! I hope this (3 year waiting time for costumers) situation will not repeat in the future.
Best regards,
D. Hofmann
