Update: still, not disabling efifb and launching a display server causes a corrupted image and freezes the system.

Yes.

No no no, if a GPU driver *fails*, it makes a lot of noise. If it only shows "enabled", it did not find any supported GPUs at all.

Which would make sense if you're on the packaged 4.16 drm, as support for VegaM was added later. You need to install 5.0 from git.

By the way: loading amdgpu only on that laptop would probably be pointless, you need to keep i915kms loaded and then kldload amdgpu.
