Has someone some solution for thie issue?

EDIT: The driver I installed https://www.displaylink.com/downloads/ubuntu

Solution 1

I had the same issue with ubuntu_18.04, kernel 5.4.0 and displaylink driver 5.2 after updating to displaylink driver 5.3.1 it started working again. apparently 5.3.1 is also for ubuntu 18.04 although not mentioned in the overview page.

Solution 2

I had the exact same problem using Ubuntu 18.04.5 LTS, kernel version 5.4.0-65-generic, on a Toshiba Portégé X30-E-133 with a Toshiba Dynadock 4K USB 3.0.

It worked for me using the "Latest Official Driver" (DisplayLink USB Graphics Software for Ubuntu, Ubuntu 20.04, Release: 5.3.1 | 05 May 2020) from the official DisplayLink website.

The exact file I used was this.

Simply download, unzip, make the .run file executable, and run it.

A reboot was necessary after the installation and the docking station worked straight away afterwards (screen attached to HDMI port, sound, and USB).

The system already had version 4.4 installed but a screen attached to the HDMI port didn't show up under Ubuntu's System Settings -> Display and Monitor, which was the reason for updating.

I did not uninstall the old version in any way before running the installer for the new version.
