> I have no idea why VENC is not working for you when using connector_status_unknown, but I just tested DPI with connector_status_unknown (i.e. changed the above func to return unknown for DPI), and it works fine with X and X omap driver. And xrandr confirms that the connection status is unknown: # xrandr Screen 0: minimum 320 x 200, current 1920 x 1200, maximum 2048 x 2048 HDMI-1 disconnected (normal left inverted right x axis y axis) None-1 unknown connection 1920x1200+0+0 (normal left inverted right x axis y axis) 0mm x 0mm 1920x1200 60.00*+ 60.00 + Grep also shows that there are many drivers using connector_status_unknown, so I'm guessing it should work fine...
