Many times such phantom ports are available in the dock connector. Or they could have just been left in the configuration but not actually pinned out. DP = DisplayPort. In theory you can daisy-chain multiple DP displays if they all support DP 1.2 [along with the GPU] using something known as "MST", but unfortunately nouveau does not support this at this time. HDMI has no equivalent concept. -ilia _______________________________________________ Nouveau mailing list [email protected] https://lists.freedesktop.org/mailman/listinfo/nouveau
