MacBook Pro 14,1 with Ubuntu 17.10 - Second display not working on dock

I installed Kubuntu 17.10 on my MacBook Pro 14,1 and made some adjustments (mostly enabling kernel modules) to make the basics work fine.
Now I would like to be able to plug my second display in a dock, but that doesn't work.
When I plug the USB-C cable of my second display directly into the mac, it works fine, the screen is detected and turns on, but when I plug it on the USB-C port of a dock that is plugged in the mac, nothing happens.
I just tried on another mac (same model) that still has MacOS, and it works. I also tried with another dock that has a power supply, and on my Linux, it works.
- Tested on 2 docks without a power supply, doesn't work on Linux but works on MacOS.
- Tested on 1 dock with a power supply, works both on Linux and MacOS.
Is there a way to fix this?

Ubuntu 17.04 is end of life, you should use a supported version.

It's not supported any more, and hence off-topic here. Currently supported releases are: 14.04 LTS, 16.04 LTS, and 17.10. Ubuntu 18.04 LTS will arrive in a week or so.

Was the MacOS removed from the system? If not, have you tried with the dock in the MacOS to eliminate the hardware as being the problem?
