Default Re: gdm blank screen for 270 under Ubuntu Natty

Ok, I'm back to natty and have progressed somewhat. The trick to getting video seemed to be adding the BusID to xorg.conf, but then I lost it when i started to debug the HDMI output. Eventually, I got video from the HDMI but now I can't get it back on the laptop display.

Moving on to the HDMI audio -- I have not been able to activate this in Linux. All works fine in Windows (as do both laptop and HDMI display), and Windows sound configuration shows 2 devices: Realtek audio and NVidia HDMI audio -- selecting the latter provides sound from the HDMI.

However, in Linux, I don't see any such NVidia HDMI device or any audio card other than card#0, which is Intel HDA. I had a similar problem with my desktop under Maverick, but this was fixed by discovering that card1 device 3 was the NVidia (hw=1,3). In this laptop, I don't see any such NVidia device in /proc/asound or via aplay -L.

Thanks, Norm
