Amdgpu USB 3 Displaylink

Support Graphics & Display

Hello. I have a displaylink monitor and I cannot make it work with Ryzen 5800u via USB 3.
Please note that I followed the arch wiki page and it worked just fine for this monitor on another (Intel) laptop.

Can you please help to setup this monitor, maybe some extra config is missing ?

I have some progress:

  1. Kernel 5.15.7-1 with evdi-git. Does not work
  2. Downgraded to 5.10.84-1 and installed evdi. Works

So I guess this is smt related to kernel version vs evdi combination.

This fork worked for me
