I have a machine I've been using as a DVR in that other OS. I recently
upgraded the tuner and video cards and decided now's a good time to do
something Mythical.
So one of the first steps is getting X displaying on the TV. The video
card (an EVGA Geforce 6200 with 512 MiB) has DVI, VGA, and S-video. I
have an S-video -> composite adapter in there. I think I have to use the
binary-only Nvidia driver. But, it won't start X. When I run
sudo /etc/init.d/gdm start
I get a brief flash of something on the TV and
May 22 01:03:17 dvr kernel: [19696.782125] agpgart: Found an AGP 2.0 compliant device at 0000:00:00.0.
May 22 01:03:17 dvr kernel: [19696.782147] agpgart: Putting AGP V2 device at 0000:00:00.0 into 4x mode
May 22 01:03:17 dvr kernel: [19696.782202] agpgart: Putting AGP V2 device at 0000:01:00.0 into 4x mode
May 22 01:03:18 dvr kernel: [19697.409739] Xorg[3733]: segfault at fffffffc eip b7f9c58e esp bfbe4148 error 4
in /var/log/syslog. There are no errors in /var/log/Xorg.0.log and no
comments at all in /var/log/dmesg. It does this three or four times,
then gives me a chance to pick a new driver. I never let it get that
far.
The current xorg.conf (minus commented-out lines) is at
http://royalty.mine.nu:81/dvr.xorg.conf
and a log from its failed attempt is at
http://royalty.mine.nu:81/dvr.Xorg.0.log.gz
I only want one monitor (a regular 4:3 CRT TV). It would be nice if it
would show something on a CRT that I'll only connect during emergencies.
How can I do this?

That is possibly the case.
Something lurking at the back of the skull says that your xorg.conf file
also requires the line in the driver section to tell x to use the S video
output. I might be wrong.

That looks like the critical error.

I got the thing to show on the TV. Lemme log in and see what I did to
xorg.conf... ah yeah, once I got it up enough to see X, I ran that
Nvidia thingy to tweak your X settings. Its "write changes to X config
file" wrote all _sorts_ of changes. Moved my comments all together at
the top of their section so I can only guess where they originally went.
And changed the names of things from sensible ones like "TV" to dumb ones
like "Monitor0". And added some options I don't think I need.
Section "Device"
Identifier "Videocard0"
Driver "nvidia"
VendorName "NVIDIA Corporation"
BoardName "GeForce 6200"
Option "NoLogo" "true"
Option "TVStandard" "NTSC-M"
EndSection
Section "Screen"
Identifier "Screen0"
Device "Videocard0"
Monitor "Monitor0"
DefaultDepth 24
Option "TwinView" "0"
Option "metamodes" "nvidia-auto-select +0+0"
EndSection
Section "Extensions"
Option "Composite" "Enable"
EndSection
It's in greyscale, so I looked on the net and all of the solutions seem
to be basically "use S-video". Would if I could but I can't -- the amp
doesn't speak S-video. But, it does speak Component, so I ordered some
4-pin S-video -> Component adapters (they were hard to find). I hope
they work.

Try out the nvtv program, possibly with the nvtvd. That should enable using
the S-video output of most NV cards, and it provides a bit more flexibility.
Be careful with that program though, because IIRC it's based on reverse
engineering, and at times I have gone a bit too far with adjustments, and
had to reset the X server. I think I used a gtk frontend to nvtv. I used
that with an S-video adapter years ago, and an Nvidia GeForce 2 IIRC with TV
out. Finding the right mode can be a little tricky IIRC, and it involved
some trial and error.
In another setup I have used a converter box. The box converts VGA from the
video card to S-video, or RCA. The box does scaling, and converts the
signal automatically. There are a surprising amount of boxes that do this.
I have so far liked the StarTech converter box. Some of the other converter
boxes generate a lot of heat from what I've read in reviews, and so far I've
been fairly happy with the StarTech. I haven't used the remote on the unit
I have yet (haven't needed to), but the rest of it works fine.
Note: some of the wireless VGA converter boxes are a bit misleading, because
they warn against using them within range of a wireless network, due to
interference.
One last thought: I didn't need to modify my xorg.conf to use the nvtv. I
had a somewhat odd setup though, because I had 2 video cards, and some weird
hacks I wrote going on in my X server.

A greyscale image can come from a PAL/NTSC confusion. Do you have a PAL
source or an NTSC source?
