The newer versions of Blender only support CUDA and HIP as render devices, whereas in Blender 2.83 we still had the option to use OpenCL for rendering. You could say the blame is on AMD for giving subpar HIP support on Linux, and that would be fair IF the OpenCL backend didn't exist in Blender 2.83.
Of course, to add insult to injury, they now don't port the RT acceleration to Linux, which just makes the experience truly inferior to Windows. As I pointed out in the original comment, this is a reasonable decision from a business standpoint. I just find it sad because Blender is one of the darlings of the open-source movement, so seeing them neglect Linux so much is frustrating.
The video and compute drivers were merged some time around the ROCm 5.0 release last year. If you have a sufficiently recent kernel, you shouldn't need to install any additional drivers.
On Debian Bookworm or Ubuntu 23.04, you can `apt install libamdhip64-dev` and you'll have everything needed to use Blender's HIP GPU rendering.
