These instructions will walk you through a simple way of confirming AMD GPU functionality on Linux, using a Fedora KDE live USB. Fedora KDE is a good choice because it offers a familiar desktop environment for Windows users, and it also ships relatively up-to-date software and drivers by default.
Everything should work out of the box, no additional setup required.
Important
Fedora 43 was released only a few days ago, at the time of writing. However, it's important to note that they have a 6 month release cycle. During a release cycle, security and bug fixes are provided, but new features generally aren't.
This means that, potentially, the kernel (and therefore the drivers) could be lagging as much as 6 months behind the latest upstream kernel release. Generally speaking, this shouldn't be an issue unless it coincides with the release of a new GPU architecture. In that case, it's possible that the kernel will be too old to support the GPU properly.
