You have too much hope in Displaylink !! I use their driver with Ubuntu 18.04 and it has a lot of bugs that have never been corrected !!
Now Ubuntu 20.04 is going to be released soon but still no avalaible updated drivers since 10 months !! and if you ask for a beta driver they don't have !!!
I have been so stupid to buy a screen using that technology !
