Nouveau - May 2011 - [Bug 37085] New: HDMI thinks it works but TV says "no signal"

https://bugs.freedesktop.org/show_bug.cgi?id=37085

           Summary: HDMI thinks it works but TV says "no signal"
           Product: xorg
           Version: unspecified
          Platform: x86 (IA32)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/nouveau
        AssignedTo: nouveau at lists.freedesktop.org
        ReportedBy: n.vivia at gmail.com
         QAContact: xorg-team at lists.x.org


It used to work. I'm sure. I used to be able to properly connect my HDMI TV.

Then I upgraded Ubuntu to Natty, installed a second partition with the
proprietary drivers in case I need audio, and linked both home directories,
which may have messed with some setting.

Now, I connect my HDMI TV and get this nice pop-up which asks me to reconfigure
my screen settings. I set the TV's resolution to 1920x1080. The system
thinks
it works, I get a huge desktop and lose my mouse pointer when it goes beyond
the right edge, but the TV says "no signal".

My xorg.conf and dmesg output are here: http://pastebin.com/TvGCPS01
I am using the minimal 4-line xorg.conf, but the same happens with no xorg.conf
at all.

Seems like different people have had conflicting results. Can everyone confirm
that things work with the latest kernel? And if not, please attach your kernel
boot logs and vbios.
