10.04 ATI SVideo shows disconnected and TV not working

[molar]

hi everyone, i've installed 10.04 on my computer with a radeon 9550, it's an old one I know.
Anyway I'm trying to get the TV output working. I've tried this solution:
https://wiki.ubuntu.com/X/Config/SVideo

the xrandr says that the S-video is disconnected alhouth it's connected.
I've tried another solution here:
http://ubuntuforums.org/showthread.php?t=1332157

This thread didn't solved the issue also:
http://ubuntuforums.org/showthread.php?t=608151

but I can't find a xorg.conf file on my system so I don't know how to add the lines. also in my case the s-video seems detected just disconnected.

any help will be appreciated.

Does this bug applies to my situation? if I understand correctly there is a patch for that, how can I apply it?

I've tried the process at http://wiki.archlinux.org/index.php/ATI#TV_out but I can't get pass the first line:

xrandr --output S-video --set load_detection 1

I'm getting the following error:

X Error of failed request:  BadName (named color or font does not exist)
  Major opcode of failed request:  149 (RANDR)
  Minor opcode of failed request:  11 (RRQueryOutputProperty)
  Serial number of failed request:  27
  Current serial number in output stream:  27

what can I do?

I've found this to be a bug:
https://bugs.freedesktop.org/show_bug.cgi?id=27649
https://bugs.launchpad.net/ubuntu/+s...ux/+bug/563983

but the bug has been solved. How can I update my system so it will make use of the patch?

Note to moderator: Please consider moving it to a different section.

if anyone is interested a custom kernel was being built with a patch to address this bug, more here:

I was having the same result. In 11.04 a working command for this purpose is:
xrandr --output S-VIDEO --set "load detection" 1

I entered this in this thread because there have apparently been some changes to variable names and the net is rife with the old erroneous variables.
