Chris? Right, I was trying to ascertain whether the intel_lvds_ddc_probe() correctly detected the missing panel. That function currently requires GMBUS to differentiate between a NAK and an IO error (bitbanging just returns EREMOTEIO regardless, iirc). So far it has been successful in detecting one false-positive for an AOpen All-in-one and hasn't fouled up LVDS detection for the laptops I have. -Chris -- Chris Wilson, Intel Open Source Technology Centre
