in version 19.10 it works more or less
 
works on 19.10 when you upgrade to 20.04lts to stop working.

Ubuntu 20.04 solution
 
This is confirmation that following the instructions on https://github.com/AdnanHodzic/displaylink-debian works with Ubuntu 20.04.

With the official drivers, even after installing flex and bison, it will not work because the makefile cannot find Build.include in the kernel headers.

After running:
sudo apt install git
git clone https://github.com/AdnanHodzic/displaylink-debian.git
cd displaylink-debian/ && sudo ./displaylink-debian.sh

Then, reboot, and "delete all secure boot variables" in bios or otherwise remove secureboot.

Hi Smhanov.
I've followed these instructions without success. I've reported here: https://github.com/AdnanHodzic/displ...ian/issues/391

Please, Could you share more details here.
What does mean `delete all secure boot variables` ?.

Regards.

I can confirm it also worked for me.
I did the above steps, rebooted, checked if secureboot was disabled (it was), when ubuntu booted the secundary screen started working.
I have the secondary screen connected to a Lenovo Thinkpad x1 thru a Thinkpad Dock.
Thanks !!

n https://github.com/AdnanHodzic/displaylink-debian works on Ubuntu 20
 
Thank you djkajo!

I can confirm it worked for me on my dell XPS and Dell D6000 dock following the instructions that you followed as well.

I hope that solution works for everyone here!

Not working after upgrade from 19.10 to 20.04
 
I have tried the displaylink-debian but it has errors - HUNK failed
I am wondering whether it would work if i did a fresh install of 20.04
I am wondering if someone has instructions for completely removing the official DisplayLink driver before trying displaylink-debian
I have a Thinkpad with Intel Graphics
