Ok, I suspect that we need to enable reporting of events from them by some = ACPI video call; and that we will then get events for them on the "Video Bus" in= put device.

In the mean time I have one last 5 minutes idea :) Let me attach another p= atch with some video-bus debugging added. --=20 You may reply to this email to add a comment.
