There's definitely a lot of variation in experiences. In my case, on my box with an RX 9090 XTX, installing ROCm via apt did "just work" and I can compile and run programs against the GPU, and things like Ollama work with GPU acceleration with no weird fiddling or custom setup. And from what I hear, I'm definitely not the only person having this kind of experience.
