I'm using version 6.10.0 which I compiled from the Debian experimental
package for my Debian lenny system.

The commands I use for turning the S-video output on are:

xrandr --output S-video --set load_detection 1
xrandr --addmode S-video 800x600
xrandr --output S-video --set tv_standard pal
xrandr --output S-video --mode 800x600 --right-of LVDS

After doing that, xrandr says:

Screen 0: minimum 320 x 200, current 2080 x 800, maximum 2080 x 800
VGA-0 disconnected (normal left inverted right x axis y axis)
LVDS connected 1280x800+0+0 (normal left inverted right x axis y axis)
0mm x 0mm 1280x800       60.1*+   60.0  
   1280x768       60.0  
   1024x768       60.0  
   800x600        60.3  
   640x480        59.9  
S-video connected 800x600+1280+0 (normal left inverted right x axis y
axis) 0mm x 0mm 800x600        59.9*+   60.3

The relevant lspci-line is:
01:00.0 VGA compatible controller: ATI Technologies Inc RV350 [Mobility
Radeon 9600 M10]

I pasted the Xorg.log to The steps I did
were: Turn TV on with the commands above, switch to VT and again the
commands from above.

Best regards,
Andreas Juch
