Fedora 30 and Dell D6000 dock

[pjw]

Hi,
Just recently got a new Lenovo Yoga C930, along with a Dell D6000 dock. The dock works perfectly under Windows, with no manual driver installation required: all video outputs work fine.
Under Fedora 30, I can't get any video out (either HDMI or DP): there is not even a flicker of acknowledgement that a monitor is connected. I've trawled through all sorts of suggested options, and haven't managed to make any progress.
I've run the DisplayLink support tool and attached the result - please let me know if anyone has suggestions to get this thing working.

An update on this for anyone else in the same position:
* I tried booting Ubuntu 18.04 off a USB drive, given this is what the displaylink driver officially supports.
* I installed the displaylink driver.
* The Ubuntu GUI display manager didn't work properly (it didn't let changes get applied etc), but I could see both monitors there.
* xrandr could configure the monitors vaguely sensibly.
* But... the result was not usable: the mouse pointer was flashing all over the screen for some reason. So I gave up and rebooted back into my Fedora install.

And when Fedora booted, it magically displayed on both external monitors and the built-in display. The dock now appears to be working perfectly fine. And there are no issues with the mouse pointer flashing all over the screens.

Summary: it is almost as if the dock or the laptop needed to be set to a certain mode to work. The Ubuntu driver did that, and Fedora for some reason couldn't.

Is your Fedora installation running X or Wayland?

Thanks

X - I think wayland got removed at some point of the process of trying to get it to work!

I am not able to make displaylink working on my two fedora workstation, at version 30. But I wasn't also at 29.

It works somehow on ubuntu, with random disconnects and extra cpu usage.
I have two d6000 so I have tested both.

I have just installed a clean fedora 30 on a brand new dell xps, with d6000 docking station.

Download rpm, install make,gcc,kernel sources and I have the displaylink service running and evdi module loaded.

xrands --listproviders gives nothing under wayland, and the local notebook monitor under xorg.

This it driving my crazy :-|
What shuld I check ?
