Just installed fresh Ubuntu 20.04 on my Ryzen 5700G, which has AMD Radeon Vega integrated. I have installed the AMD driver. I'm unable to choose the iGPU in any program. For example Blender shows that there's no compatible device - I've tried Blender 2.9 with OpenCL and Blender 3.4 with HIP - same result.
On a laptop with Ryzen CPU and integrated Vega 8, running Windows, I can see the card in Blender 2.9
What do I have to do, to have the GPU visible?
