Dell D6000 And XPS13 9360

[Toto]

Hello !
I've recently purchased a laptop (Dell XPS13 9360) along with a Dell D6000 dock. After installing the drivers, the dock didn't work when I plugged one or more screens. I've managed to get the screens working by using the old intel drivers as suggested by DisplayLink (http://support.displaylink.com/knowledgebase/articles/1181623-displaylink-ubuntu-driver-after-recent-x-upgrades). Unfortunately, I still have some issues for which I can't seem to find an answer.

My first problem is that there is a lot of lines which look like that in my dmesg :

[drm:drm_wait_vblank [drm]] *ERROR* Unsupported type value 0x45, supported mask 0x7400003f

I haven't been able to find the source of that problem.

The other problem that I have is the following : the dock randomly disconnects and the screens turn off. I say randomly because it can happen after a few hours or just a few minutes. The dock reconnect a few seconds later, but the screens are still turned off, and I have to unplug the usb-C cable and plug it again. After doing it a few times, nothing works and I have to reboot my computer. Is there a fix for that ?
I'm using Ubuntu 17.04 and as far as I know every thing is up to date.

Same problem with my new DELL XPS13 (Ubuntu 16.04) with dock D6000 : random reset, need to unplug and plug to work....

After a few days of struggling, I managed to find a solution on Ubuntu 17.10. Hope this works for everyone having problems with the D6000 dock. Below format is markdown (to lazy to convert it)
