TV out Radeon

Hi all, I am trying to get TV out to work on my laptop with Ati Mobility X300, When I was on debian I could use the ati catalyst tool which I am unable to install on arch. It is not very big deal, but there definetely is a way to get this to work with opensource radeon driver. Now I've gotten here: The output is 800x600 since the output doesn't support higher resolution. I invoke this output by this script I made:

#!/bin/sh
xrandr --output S-video --set load_detection 1 
xrandr --addmode S-video 800x600
xrandr --output S-video --mode 800x600
xrandr --output S-video --set tv_standard pal
#xvattr -a XV_CRTC -v 1

with a little help of some howto page. What the page didn't say was how to solve the problem: The TV output is just cut desktop -> TV[800x600] LCD[1024x768] like that. How can I do that? On debian it worked, I suppose it is just lack of knowledge about the xrandr tool. Thanks

Here http://www.thinkwiki.org/wiki/How_to_ge … phic_cards is the howto page.

Nothing guys? It really bugs me... I hope there's somebody who knows something about radeon drivers.

The TV output is just cut desktop -> TV[800x600] LCD[1024x768] like that. How can I do that?

You're going to have to explain that to me. Do you want the same output on both screens? Do you want to see part of the desktop on the tv? do you want the tv to be next to the desktop (no overlapping?)

you can dictate location of the screen with --left-of, --right-of etc... or --pos <value>x<value>

man xrandr has some clear examples on this

EXAMPLES
       Sets  an output called LVDS to its preferred mode, and on its right put
       an output called VGA to preferred mode of a screen which has been phys‐
       ically rotated clockwise:
              xrandr  --output  LVDS --auto --rotate normal --pos 0x0 --output
              VGA --auto --rotate left --right-of LVDS

       Forces to use a 1024x768 mode on an output called VGA:
              xrandr --newmode "1024x768" 63.50  1024 1072 1176 1328  768  771
              775 798 -hsync +vsync
              xrandr --addmode VGA 1024x768
              xrandr --output VGA --mode 1024x768

       Enables panning on a 1600x768 desktop while displaying 1024x768 mode on
       an output called VGA:
              xrandr --fb 1600x768  --output  VGA  --mode  1024x768  --panning
              1600x0

       Have  one  small 1280x800 LVDS screen showing a small version of a huge
       3200x2000 desktop, and have a big VGA screen display the surrounding of
       the mouse at normal size.
              xrandr --fb 3200x2000 --output LVDS --scale 2.5x2.5 --output VGA
              --pos 0x0 --panning 3200x2000+0+0/3200x2000+0+0/64/64/64/64
