Default Problem with HP dock and Ubuntu

Hello all,

I have a problem to run HP universal dock (USB-C) with my laptop in Ubuntu.

USBs and NIC works fine, but not Display outputs (2 displayPorts, I have two full HD monitors). Both full HD monitors are black and without signal from dock.

I installed display link driver 5.2.14 and also latest dkms. Installation was successfully done.

My PC:
HP ProBook 440 G6
Ubuntu 18.04.3 LTS (with latest updates)
Intel® Core™ i5-8265U CPU @ 1.60GHz × 8
HP universal dock USB-C (2UF95AA#ABB)

Can someone tell me please how to solve this problem?

Thank you in advance for your response.

To be able to determine the root cause for this behaviour and learn a bit more about your configuration I will need to take a look at the log files you can collect them by following steps In this article.

Thank you,
