Driver can be found here: "https://www.amd.com/en/support/kb/release-notes/rn-amdgpu-unified-linux-20-20"

Just extract to a directory and run the command "sudo amdgpu-pro-install -y" and then reboot.

Only thing to be aware of is if you try and use only the external monitor with your computer screen off you will get 3 sec delay on clicks.

To make it work perfectly make sure the screen of the computer your DisplayLink is plugged into is never off.

Hope this helps.

I've tried this solution and worked perfectly.

Thank you very much man!
