[mythtv-users] ATI Radeon VGA to RGB SCART problems

[Rob Beard]

Hi folks,

I was hoping someone might be able to help?

I've have had a cable made up to connect the VGA output from my ATI 
Radeon 9200SE.  I'm trying to configure Ubuntu (Fiesty 7.04 Beta) to 
display X Windows on the TV using this ATI card.  When I plug the cable 
in the TV will default to the correct scart socket but I don't get 
anything on the screen apart from a slight brownish glow right at the 
top of the screen which fades down the screen to black.  It appears that 
the TV is switching to 60Hz too.

When I restart the machine the TV looses sync as it goes through the 
bios and bootup (I figured this would be the case with it being too much 
for the TV to handle).

The configuration I used from was from the MythTV wiki here: 
http://www.mythtv.org/wiki/index.php/RGB_Scart

I adjusted the video card identifier so it would find the screen.  The 
instructions I used for the cable were from here:

The contents of my xorg.conf are below:

This is the first time I've tried something like this and I'm a bit 
stuck.  Could anyone advise what I'm doing wrong here?

Ta,
