[XFree86] Using TV-OUT on a Radeon-7000-based dual-head card

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Alon,

    TV-out is not supported yet by either the xfree86 or DRI trees.  I
believe there may be experimental support in the gatos project
(http://gatos.sf.net), but I've never tried it.  You might inquire
there.  Also, there are only two display controllers on radeon hardware
so it can only drive two outputs (some combo of DVI, CRT, and TV-out). 


hope this helps,

Alex

Hello all.

After setting up my Hercules 3D Prophet to do dual-head (thanks for the
help again Alex & Co.:) ), packed with new enery to fight yet another
battle, I want to use my TV-out to see DVDs (or any other thing).
Being the optimistic I am I thought that simply plugging in the RCA
cable from the card to the TV would do the trick -- it didn't. This is
what I have so far:

1. I learned that the TV shows (tries to show) the contents of the
second CRT monitor (I have two standard VGA connectors).

2. The image shown on the TV is just a bunch of lines dancing around
the
monitor.

3. I do know it's trying to show the image from the monitor since I can
things change on the TV when they change on the monitor -- for example
opening or closing a window with a white background will create or hide
a brighter section of lines on the TV

4. When I try a single-monitor XF86Config the TV is blank

5. In console mode the TV is blank

6. I've tried lowering the resolution of both screens or one of them to

800x600 -- same thing

7. When the TV-out cable is connected, the second CRT displays badly,
as 
if its cable is malfunctioning (worse colors, and some bluriness)

Some Google searching led me to a small utility name atitvout. Running 
atitvout detect gives me:
CRT is attached.
TV is attached via S-Video.

(is sais "TV is attached" even when it's not)

Trying to use it to actually activate the TV gives me no results or 
error messages in the form of "unsupported by your card, blah blah
blah".

Anyone has any leads as to where I can find relevant information, or 
what steps I need to do to make this work?

And last but not least, system info:

Redhat 9 (with many RPMs from Fedora)
Kernel: 2.6.0test9
XFree: compiled by myself, 4.3.99.14
Video-card: Hercules 3D Prophet 7000 dual-vga-head + tv-out (Radeon 
7000-based)



Thanks alot.
