I'm trying to get the S-video out (which I'll call the TV out from now on) to work on my Inspiron 1420n, running Fedora 8. It has an Intel GM965 chipset, with an X3100 graphics card. The X graphics driver is "intel"; The "i810" driver doesn't work with my graphics card.
The basic problem is that I can't get anything to appear on the TV screen. I know the interface to the TV is working because the same setup works if I connect it to a windows laptop's TV out.
I'm trying to get it working using xrandr, as I've seen several places on the web suggesting this was a good way to do it, as then you don't have to kill X to switch the TV on and off.
I've tried several different output resolutions using xrandr, and I've also tried all the different values for the TV_FORMAT parameter to xrandr (NTSC-M, NTSC-443, NTSC-J, PAL-M, PAL-N, PAL, 480p@59.94Hz, 480p@60Hz, 576p 720p@60Hz, 720p@59.94Hz, 720p@50Hz, 1080i@50Hz 1080i@60Hz, and 1080i@59.94H), but I can't get any combination to work. Depending on which TV_FORMAT I choose, xrandr detects different output resolutions from the TV, and some xrandr commands do cause the TV screen to flicker, so there is
some communication going on between the laptop and TV.
When I enable the output, the desktop changes in such a way that I think it's configured the X 'screen' correctly - the desktop picture stretches vertically and the bottom panel disappears, I assume to the bottom of the newly-enlarged X 'screen', but something is just not quite right somewhere as there's no output on the TV. When I turn the TV output off again, the desktop goes back to how it was originally.
There's some sample xrandr output at the end of the post.
Here are the commands I'm using:
Code:
[david@neptune] $ xrandr --output TV --set TV_FORMAT 480p@59.94Hz
[david@neptune] $ xrandr --output TV --mode 1360x768 --below LVDS
[david@neptune] $ xrandr --output TV --off
The first command sets the TV_FORMAT, the second should enable the TV out, and the third should disable it.
If anyone could offer any suggestions I'd greatly appreciate it.
Regards
David Gee
