AMD GPU (RX 6800 XT) is not detected on Linux Mint 21.3. What are my options?
#1
I've followed every guide I can find on here, Reddit, and elsewhere and am at a total loss on getting an RX 6800 XT to even be detected, much less work, any guidance will be helpful. I'm running Linux Mint 21.3, kernel 5.15.0-113-generic.

The command lshw -c video | grep 'configuration' returns driver=amdgpu with no version number, but during troubleshooting I reinstalled amdgpu using amdgpu-install_6.1.60102-1_all.deb, the most recent I could find.

I attempted to install ROCm during my troubleshooting attempts following the guide here: https://rocm.docs.amd.com/projects/insta...buntu.html; however, the steps failed at 'sudo apt install rocm" with 

Code:
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created

The following information may help to resolve the situation:

These instructions were last updated two days ago, and I haven't been able to find a work around nor install ROCm. I recall this also being an issue when I set up Stable Diffusion back in 22, but I was able to make a workaround then and I'm hopeful I can here as well.

I've attempted essentially every walkthrough I found when searching "AMD GPU" on here if it applied to any similar linux distro. I have also tried different kernels, including 6.5.0-41.

I'm using hashcat v6.2.6. ./hashcat.bin -I returns the following:

So my CPU is detected, at least, but when I try to run hashcat with "./hashcat.bin -m 22000 /path/to/file.hc22000 /path/to/wordlist.txt" I get the following output, suggesting there are issues detecting my CPU (also AMD)

I found this thread: https://hashcat.net/forum/thread-10695.html, but I can't install rocm, and am not using a VM. There's conflicting information on that thread as well, with one user saying "uninstall pocl" and another saying "install pocl". The pocl package mentioned is already installed on my system.

Sorry if it's too much information, I've been working on this all week and everything's starting to blur together and I want to make sure I post everything relevant. If more information is needed, lmk. I don't use Windows at all and don't have access to an Nvidia machine. 

Ideally, I want to run with my GPU, but I'll accept a CPU option if that's the only way to make this work. Or is AMD just fully incompatible with hashcat? If so, what other options could I use to crack the file? Thanks for your help.
