My company used to have some display link docks, which I was unable to use due to bugs in the Linux implementations.
For a while I'd keep an eye on updates to see if they'd been fixed but they never were before we moved office.
I'm going to be quite sure we don't get any more in any future offices (we don't have them at our current office)
Every DisplayLink hub or dock or adapter I've tried using has been a terrible nightmare. I've tried on Linux, macOS, and Windows. Now I actively avoid them.
