Now I am trying to connect my TV using HDMI port, but wasn't so lucky with that. I would like to know the current status of HDMI out support for GF108 (NVC1). I am trying with the latest code from nouveau/master tree (2fee6f5). When I connect the tv, it's not getting detected by the laptop. I see a small change in brightness of the laptop screen for a moment and nothing else. Usually there is nothing in the dmesg as well, but once I saw the below line.
