1 out of 2 external displays lagging on Ubuntu 20.04

Hi Zixemike,

I have been able to run 20.04 without tearing by using the amdgpu-pro drivers.
Only thing to be aware of is you need to join displays with you computer or it will slow down to a 3 second lag. You cant just have your DisplayLink monitor on and your computers monitor off. It seems to work perfectly otherwise.

Driver can be found here: https://www.amd.com/en/support/kb/re...ed-linux-20-20

Just extract and run the amdgpu-pro-install -y command.

Hope this helps.
