Displaylink not working

Hi,

I have been having trouble using my usb-c dock which works with displaylink.
Followed the docks but without success.

The system does not even seem to recognize the displays. The dock itself is working properly since I am using it as a hub for keyboard/mouse/… as well. Next to that I have Windows and mac machine for work which also seem work without any issues.

Have you followed this guide yet?

Do note:

DisplayLink devices on Linux still only have experimental support. While some people have had success in using them, it is generally not an easy process and not guaranteed to work.
