I guess I have some digging to do in that direction. Thank > you. In i915 we register both a HDMI and a DP connector for the same physical DP connector, and a sink attached via a DP++ dongle/cable will appear on the HDMI connector instead of the DP connector. But I don't know if nouveau follows this same pattern or not. -- Ville Syrjälä Intel OTC _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
