For ages, I have been trying to get S-video output on my Mobility Radeon 7500 (driver radeon) in Linux with no success.
From some initial Googling, I nearly died when I found out I’d have to compile some GATOS driver to get some form of TV-out. Today, however, I stumbled across a set of three commands that worked for me with no such recompiling necessary:
xrandr --addmode S-video 800x600 xrandr --output S-video --mode 800x600 xrandr --output S-video --set tv_standard pal
Those instructions only apply to RandR 1.2–powered boxes (i.e. Ubuntu 8.04 and above) — if you have an earlier version, I have no idea what to do. Upgrade.
The above code will set your TV-out to 800⨯600. For some reason, 640⨯480 does not work for me.

Cool!!!!!!!!!
It works!!!!
my laptop IBM R40 s-video connected to RGB scart transfers video on tv
Thanks a lot, Arm & Aysha
Awesome. Thanks for the feedback.
What the heck is RandR? Is that part of X or something specific to Ubuntu? If the former, then you don’t need to “upgrade” to Ubuntu, it’ll run fine as long as you have the latest version of X.
RandR is part of X.
I was a bit hesitant to approve your comment, Uri, as it was very troll-like.
Sorry if I came across as a troll.
Been waiting years for that… at one point, I kept win98 running on an older laptop just to have video out…
Guess I got a little excited because I can finally get video out on my laptop
tks.. its working
yeah!
That worked with puppy Linux too
But where’s the colors??
I have ibm t30 with radeon mobility 7500
Did you guys get colors right away?
Or is it my tv that does something wrong…
ntsc vs. pal … does that have something to do with it?
I actually got black and white when I first did it, but you’re right — it’s because of NTSC vs. PAL. Unplugging the TV, disabling the output, plugging in the TV, and enabling the output always used to fix it for me.
As to how to force it to go NTSC or PAL, I have no idea. There’s probably some hidden var you can set that will do the job.
for ntsc…
xrandr --output S-video --set tv_standard ntscCheck this out if you want a little more info on this. I was very excited when I could finally get video out of my radeon 7500 in Linux. I dont need to use Windows anymore!!!
Thanks, Ryan!
