I am using Zorin OS 16.3, using kernel 5.15.0-86-generic. Just installed the OS and updated it. My AsRock Challenger RX 6600 isn't being recognized as RX 6600 within the OS. I have attached multiple screenshots for reference. I have tried installing the proprietry drivers but it still doesn't solve the problem. I reinstalled the OS, just to get a clean start for getting help from the forum.
Asrock challenger 6600 is a graphics card whose component is AMD's GPU which is being recognised
No orries there
AMD® Dimgrey_cavefish is just the open source driver name for RX 6600 as said here:
(I just happen to have the same GPU in my old eGPU as you, though it's a Sapphire Pulse and not ASRock Challenger)
I have also Sapphire Pulse RX 6600
