> The first question is, what exactly is a "mini-DVI to Video Adapter"?

Of course, but I have no idea.  It's a black (well, white) box to me.
To tell you the truth, I always assumed it was a dummy thingy that exposes the
S-video signal from mini-DVI.

Its size seems to indicate that it has a bit more than just wires, so maybe it
does some conversion, but I expect the only conversion it does is from S-video
to composite.

Still, I'm not sure of that, because as shown in my `xrandr' output, the
nouveau driver seems to detect this adapter as a "DVI-I-0".

You mean using "xrandr --newmode"?  I'll try that, thanks.

Is there something I can do to help get TV-out support?
