Spent all afternoon trying to get a 3080Ti working on Fedora Workstation 38. I got Automatic1111 working without any issues so long as I bypassed the cuda check. Nvidia has terrible documentation and everything is outdated. Like F38 was released a long time ago and they have no support yet. F37 is the last supported on their website. I was thinking I would follow whatever RHEL documentation and be fine, but they pay walled that info. I found 3 other sources from Fedora magazine and forum, but none of them worked. Fuck IBM and Redhat. None of the options actually managed to blacklist the open source driver and get the blob working properly.
Tomorrow I’m going to try try Pop OS. They have an ISO prebuilt with the nvidia binary turd prepackaged. I’m also thinking about using Distrobox, Atoms, and Podman to build on top of Pop as an unmodified base. I may finally try Nix as a package manager too.
Most SD stuff requires specific versions of everything, and as you say the documentation is poor even on Windows. Try other forks, and you may get lucky.
