Can you remind me if you've tested this already with other distros? And, if not, can you perhaps give this a try? E.g., knowing if this works using a recent enough Fedora as a guest, as they ship upstream-like kernel (kind of like Tumbleweed), but any other data point helps. As Stefan said, it still seems a DRM issue to me, so it'd be cool to know if we're the only one that are failing...
