Ubuntu 20.04 Display Link with Ryzen (integrated graphics) SLOW refresh rate

[myersrj]

Hi there

I have been able to run 20.04 without tearing by using the amdgpu-pro video drivers instead of the open source ones that come by default with Ubuntu.

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.
