Hmm. Judging from your automated screenshots, the login never appears.

HOWEVER - it has had a fix for a NULL pointer dereference in the meantime - can you check whether the current top of tree happens to work for you? Maybe your problem isn't due to "that commit does unnatural things", but simply due to the bug fixed in d89c0c8322ec ("drm/virtio: Fix NULL dereference error in virtio_gpu_poll").
And if it's still broken with that commit, I'll happily revert it and people need to go back to the drawing board.
I sent another mail yesterday which is now at https://lore.kernel.org/lkml/CADVatmOOzCxAgLhCu1tTz=44sgRDXds5-oMZ3V0w4f5kLC... I will just pase that here for you.
Last night's test on 66f4beaa6c1d worked fine. So I guess this has now been fixed.
I have not done a bisect to see what has fixed it, but looking at the log I think it will be that NULL pointer fix.
