[mythtv-users] Nvidia and DVI to HDMI cable, no signal.

[clemens at dwf.com]

This is a continuation of my discussion in the stream "xorg for Nvidia and
DVI to HDMI cable."  I have changed the title since the question is somewhat
different.

---

Re my previous note about DVI->HDMI, I had a xorg.conf that contained lines 
that I had seen from various postings from GOOGLE.

the Nvidia driver (actually the piece of code that it dumps in xinit.d) 
REPLACED my
xorg.conf with the following:

---

# Xorg configuration created by livna-config-display

Section "Files"
	ModulePath   "/usr/lib/xorg/modules/extensions/nvidia"
	ModulePath   "/usr/lib/xorg/modules"
EndSection

Section "ServerFlags"
	Option	    "AIGLX" "on"
EndSection

Section "Device"
	Identifier  "Videocard0"
	Driver      "nvidia"
	Option	    "AddARGBGLXVisuals" "True"
EndSection

Section "Extensions"
	Option	    "Composite" "Enable"
EndSection

Thats about as minimal as you can get, and is going to assume all defaults.
And with this (I assume) it actually sees the TV, which is a SONY Bravia
and I see the following messages from the Nvidia in the /var/log/Xorg.0.log

Note that it sees the Sony recoginizes the Digital Connection (DFP).
There are some warnings, but no apparent errors.

But I see no video (the TV says that its seeing no signal).

Thoughts?
