View Full Version : [all variants] ATI Radeon 7500 tv-out issue.

July 5th, 2008, 02:12 AM
Hi everyone,

I have setup a Mythbuntu box on an old Dell GX269. The machine has a ATI Radeon 7500 VGA card with tv-out (S-video). I'm using the "Radeon" driver and it seems to work fine. I want the machine to only use the tv as its display - no monitor!

Currently I have to type in the terminal:

xrandr --addmode S-video 800x600
xrandr --output S-video --mode 800x600
xrandr --output S-video --set tv_standard pal
to make the s-video work.

Is there some way i can edit the xorg.conf file to only use the s-video as display and to do this automatically so i can take the monitor away?

Ok, I fixed my own problem.

To get the S-video to work on boot-up and without the VGA, I added this to my xorg.conf file:

Section "Device"
Identifier "ATI 7500"
Driver "radeon"
Option "ForceTVOut" "true"
Option "TVStandard" "pal"

Section "Monitor"
Identifier "S-Video"

Section "Screen"
Identifier "Default Screen"
Device "ATI 7500"
Monitor "S-Video"

I removed the VGA monitor settings altogether.:)
