Having trouble installing a piece of hardware? Want to know if that peripheral is compatible with Linux?

SVIDEO -> Composite messed up in X, fine in Windows?

I'm trying to plug into a craptastic TV that has only composite in (no SVIDEO)

Under Windows this works fine, though it is ugly (duh?).

Under X (using ATI's fglrx 3.9.0 drivers) the picture shows up, is far more legible than in windows, but shows up in black and white with strange crosshatching. How do I get this to work right... full color?

I know there is a fix for this for nVidia cards using nvtv, but I'm unaware of a similar utility for ATI cards.

IBM T41p (2373GEU)
Pentium-M 1.7GHz
1024MiB PC2700
ATI FireGL T2 128MiB
Standard SVIDEO out to RadioShack composite<->SVIDEO adapter

Arch Linux
fglrx 3.9.0
KDE 3.2.3

Does anybody have any insights into this?

I had the same problem. I think it's a composite/S-video problem. I fixed it after a couple of headache.

That's what i did:

1. Configured fglrx driver for Dual Head in XF86-config
2. Installed the atitvout package.
3. run "atitvout detect pal auto active tvout"
4. restart X server
5. I got color TV.
6. :-)

By the way, how did you setup the fglrx driver, ie XF86-config: dualhead, clone, ... ???

Have fun

I've tried dualhead and clone. Clone seems to be messed up no matter what. Dual head works for svideo.

atitvout doesn't work on my system...
