--- Comment #13 from Pontus Gråskæg graaskaeg.via.forwarder@neverbox.com --- OK, I was misled by the errors in the dmesg log:
[ 14.186318] [drm:construct [amdgpu]] *ERROR* construct: Invalid Connector ObjectID from Adapter Service for connector index:1! type 0 expected 3 [ 14.186458] [drm:construct [amdgpu]] *ERROR* construct: Invalid Connector ObjectID from Adapter Service for connector index:3! type 0 expected 3 [ 14.186592] [drm:construct [amdgpu]] *ERROR* construct: Invalid Connector ObjectID from Adapter Service for connector index:4! type 0 expected 3 [ 14.186725] [drm:construct [amdgpu]] *ERROR* construct: Invalid Connector ObjectID from Adapter Service for connector index:5! type 0 expected 3
Apologies for the misconception.
