tv-out xrandr problem


Hi all. I've been away from linux for a very long time and it's good to be back. I was hoping someone could help me with my s-video tv-out problem.

I am using a widescreen toshiba laptop running xubuntu hardy with an ati-mobility radeon. I am using the open source ati drivers (my card is no longer supported by the proprietary ones). In order to enable tv-out I execute the following commands:

xrandr --addmode S-video 800x600
xrandr --output S-video --mode 800x600

The tv screen then turns from just black to black with which/grey lines flying all over it. My laptop screen experiences no change. I'm running compiz right now.

I have not edited my xorg.conf at all since install. Here is a copy of it.

==================================================================

# xorg.conf (X.Org X Window System server configuration file)
#
# This file was generated by dexconf, the Debian X Configuration tool, using
# values from the debconf database.
#
# Edit this file with caution, and see the xorg.conf manual page.
# (Type "man xorg.conf" at the shell prompt.)
#
# This file is automatically updated on xserver-xorg package upgrades *only*
# if it has not been modified since the last upgrade of the xserver-xorg
# package.
#
# If you have edited this file but would like it to be automatically updated
# again, run the following command:
# sudo dpkg-reconfigure -phigh xserver-xorg

I'm really stumped by this. Any help at all would be appreciated.

Thanks

I'm not sure how this applies to xubuntu but in Hardy Heron (8.04) I do the following.

On my Fujitsu-Siemens Amilo L1300 and Hitachi 32" I connect the TV to the vga out and then run "xrandr -q" this should show the VGA output to be connected.

After this I run the standard screen resolution under preferences and click "detect screens"... It might take a while and then I set the resolution for the TV to 1024x768 (I haven't been able to get it to accept a higher resolution).

I hope this points you in the right direction.
