Has anyone here gotten X to work on the S-video output of a dual-output
Radeon card? I've been messing with my X configuration trying to get my
card to drive a signal into a TV and I've gotten all of nowhere. There's
a lot of noise on the web about framebuffers, dual head versus cloned
versus Xinerama, proprietary versus reverse-engineered drivers, etc., and
I am having a hard time figuring out what is supported and what is simply
not possible.
My ideal setup would be to be able to use the computer with the one head,
as I have been, normally, and occasionally fire up the S-video out with a
totally separate X session to display videos, where I could optimize the
display resolution and everything. But again, I have no idea if that's
possible.
A nice fallback would be to use the comptuer normally, occasionally
turning on the TV and having a cloned output of the computer's screen,
downsampled to the TV's resolution (does the framebuffer do that? what
does the framebuffer do? What is a framebuffer? And don't say STFW,
because the Web doesn't seem to know, either)
Presently I can't get anything to display to the TV at all, except that
if I boot with it turned on then i get the bootup process, up until X
starts, at which point it goes to crazy interference.
Any help appreciated. I don't know what information is relevant to
provide. My card is a Radeon 9200 with VGA and S-video out; my X server
is XFree86 version 4.3.0.1 (Debian) [thanks again for helping me get back
to XFree86 from Xorg]. I think I understand the XF86Config file pretty
well at this point.. I just have no idea what to put in it.
An off-list discussion would be fine, also.
Thanks in advance,
Brandon
