Black&white screen with TV-out
#1
I've installed the minimal XBMCbuntu, according to the guide by Luigi. Since I have an old ATI card, x1250, I have to use the open source driver "radeon" (AMD don't support in anymore).

After a large ammount of effort, I finally got the driver working and also with TV-out (s-video -> CRT). The problem is that the drivers only support ntsc-standard (not pal). Since my TV is european, it's a pal-TV. I'm 99% certain that it is supposed to support ntsc signal aswell, and it kinda says so in the manual. But I still only get a black&white screen.

Has anyone experienced something similar and might be able to help me? I have previously used TV-out with this computer without problem.

My xorg.conf...

Can someone please move this to the Linux-section? Confused

Just to verify:
Does the screen always display black and white no matter what is on screen from the computer?

If so, then I would suggest trying a different cable. S-Video splits color data from chroma data, so that colors are preserved better than a composite cable. Typically, if you get no color and only chroma (black/white), then it could be something with the tv/computer connectors, or the cable itself (ie, a bent/broken pin in the connector on the tv/computer or cable ends).

No, I only get black/white screen when the linux-gfx-drivers "kick-in". The bios-logo during boot has colour. And tv-out from my laptop works fine, using the same cable.

This is why I suspect it has something to do with the signal the gfx-card "choose" to send, using these drivers and settings. Maybe a setting in xorg.conf, or even perhaps on the TV... Huh

What kind of connection do you use now? Composite? Really sounds like an NTSC-PAL issue to me. You could give an S-Video cable a try since it doesn't suffer from NTSC-PAL color-encoding issues....

I use a s-video cable, connected to a scart-adapter (see pictures...)

You're saying this type of cable should be indifferent to pal/ntsc?

Well, for the most part since the difference between PAL & NTSC is mainly color encoding and since S-video has seperate chroma/luma it doesn't need color encoding so the only difference would be the refresh-frequency (50Hz vs. 60Hz) but that shouldn't be at play here. Try connecting with composite instead and see what happens then...

I don't have a composite connector on my computer. Would it be the same to use a s-video -> composite adaptor?

This *could* work but it's dependend on too many factors. Just give it a try and see how it goes...
