Hi -

I'm trying to get S-Video output from my ATI 9200 video card on SuSE Linux Pro 9.3. My PC has three cards; I need S-Video out for two of them, and VGA out for the primary.

I'm using the radeon driver; both the built-in version that came with SuSE, as well as a version I built myself from the tv_output patch on the Gatos site. Both fail the same way.

I've tried the ATI fglrx driver: it does S-Video, but it cannot handle multiple outputs. So I cannot use fglrx: I must figure out some way to do it with radeon (or some other Suse-compatible driver).

Here are my monitor specs:
HF: 15.6kHz
VF: 60.0Hz

Here are the relevant portions of my /etc/X11/xorg/conf:
Section "Device"
BoardName "RV280 5964"
BusID "2:2:0"
Driver "radeon"
Identifier "Device[1]"
VendorName "ATI"
Option "TVOutput" "NTSC"
EndSection
...
Section "Monitor"
Identifier "Monitor[1]"
ModelName "Unknown"
VendorName "Unknown"
UseModes "Modes[1]"
HorizSync 15 - 31.5
VertRefresh 60
EndSection
...
Section "Modes"
Modeline "800x600" 4.2 800 840 968 1056 600 601 605 628
Identifier "Modes[1]"
EndSection

And here's the resulting /var/log/Xorg.0.log error file:
...
(II) RADEON(1): Monitor[1]: Using hsync range of 15.00-31.50 kHz
(II) RADEON(1): Monitor[1]: Using vrefresh value of 60.00 Hz

<= THE RADEON DRIVER REQUIRES 800x600 RESOLUTION FOR NTSC
OUTPUT: 640x480 OR SOME OTHER VALUE *WILL NOT WORK* FOR

????Any suggestions?????

Any idea what "Modeline" settings I can give it so that it will at least
accept the "800x600" part without second-guessing me and substituting "640x480" instead????

Thank you *very* much in advance!

on your screen that you want s video out on did you edit the horizonantal and the vertical refresh rate properly. what i suggest is to find out what those values are and then edit your xorg.conf to those values then try it . if the refresh rate is not right the module will default to 640x480.

Hi -

Thank you very much for the response.

The S-Video line is plugged in to a generic, glass-CRT, 27" monitor. Here are the specs:

Here's (one of *many* combinations) of xorg.conf "Monitor" section I've tried:
And here's (one of) my (failed!) attempts at a modeline that tries to coerce these specs into 800x600 resolution (the tv_output driver *needs* to be at 800x600 in order to take effect):
I can't think of anything else I can do as far as editing the horizontal and vertical refresh rates properly - please let me know if you have any ideas!

I think the $1,000,000 question right now is to figure out why the Xorg module doesn't think the refresh rate is "right". Or to figure out the right ModeLine values.

Thanx again - any other ideas/advice would definitely be appreciated!!!

the vertical refresh rate is wrong it has to be two numbers seperated by a hyphen like 30-70 or something like that .go to the monitors manufactuers website they will have the refresh rate of the montior in question


my xorg config is like this :



Section "Monitor"
Identifier "Generic Monitor"
Option "DPMS"
HorizSync 30-81
VertRefresh 56-75


thats what it is suppose to look like
