I’ve purchased a Dell “universal” USB 3/USB C docking station featuring Display Link, essentially allowing you to use it to drive external displays with the intention of using it for my laptop when sat at a desk with external monitor, mouse and keyboard. Since I run Ubuntu or Linux Mint as my primary operating system, some extra steps were required to install the Display Link drivers.
The first thing you need to do is download the Display Link drivers from the official website: https://www.displaylink.com/downloads/ubuntu
Once downloaded, it’s a reasonably straight forward process to install the drivers. First thing that’s required is to install pre-requisites
sudo apt-get install dkms libdrm-dev
Next run the downloaded file replacing the version number with whatever the one you downloaded is. (Note, this command assumes you’re in the appropriate directory already):
Once finished you should have a message asking if you are running xorg and if you want to reboot. It’s actually best to reboot regardless of your display driver, so select
Y for yes and let your machine reboot. Then you should be able to plug in your USB dock and your external devices with them all working.
For more information, the Display Link website actually has some good resources. Checkout their Ubuntu setup guide here: https://support.displaylink.com/knowledgebase/articles/684649
