Hello, I am on EndeavourOS (Plasma 6.4.2), on a laptop with an AMD iGPU and an Nvidia dGPU (using `nvidia-open-dkms` driver). Graphics Processor 1 does show `AMD Radeon Vega 10 Graphics`, whether I am on Wayland or X11. Now on Wayland, Graphics Processor 2 says `llvmpipe` and on X11 it shows the iGPU again. Now I want to mention that my system works perfectly fine and as intended, including the Nvidia card, so I guess this is merely a cosmetic issue.
Means your vulkan stack is likely not installed correctly. *** This bug has been marked as a duplicate of bug 499882 ***
Installing `vulkan-radeon` solved the issue.
