Hi. I’m running Manjaro KDE on a Precision 5520 laptop with a Vega 56 connected as an eGPU in an Akitio Node.
Below is the system configuration of my machine.

EndSection I have gotten the eGPU configuration to work well with an NVidia 1070 and replaced it with a Vega 56, but I’m struggling to get it to work with AMD xrandr --listproviders
Providers: number : 2
Provider 0: id: 0x77 cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 3 outputs: 5 associated providers: 1 name:modesetting
Provider 1: id: 0x3f cap: 0x5, Source Output, Source Offload crtcs: 0 outputs: 0 associated providers: 1 name:modesetting  
  1. inxi shows the graphics driver as N/A for the AMD card.
  2. xrandr --listproviders doesn’t show the AMD card :frowning:
  3. When I try to do a ‘startx – -layout egpu’, I get the following error
 
AMDGPU(0) : [KMS] drm report modesetting isn't supported.
(EE) Fatal server error : (EE) no screens found 

I also have the xf86-video-amdgpu and mhwd-amdgpu packages installed. No catalyst drivers were ever installed. Can someone please help to resolve this issue?
