nouveau and hdtv-out

Is it possible to get hdtv-out going with nouveau?  i have the breakout pod supplied with my nvidia 7600 gs card, and i used it to output 1080i to my tv via "TVOutFormat" "HD1080i" in xorg.conf.  well, since the 190.xx releases, this causes a kernel panic on my machine, so i said to hell with and just switched to nouveau, but haven't seen anywhere how to get hd going with nouveau.  i can output a standard resolution, but because it is hooked up via component cables, the picture has a blue tint to it.  any help at all would be appreciated.  thank you.

EDIT: the 1080i out was with nvidia driver
Another EDIT: the option is "TVStandard" not "TVOutFormat".  But i did use "TVOutFormat" "Component" to force component out.

Is your TV listed in the output of "xrandr"?

Re: nouveau and hdtv-out

yessir it is, but only as having a possible max res of 1024x768, which is obviously not the case.  Which works just fine, but with the aforementioned blue tint.  So my problem is twofold:  force component output, and enable 1920x1080 interlaced.

Re: nouveau and hdtv-out

Hmm.  You should probably ask the nouveau guys if the support is supposed to be there, or if its easy to add.  Also, try more recent versions (kernel26-nouveau-git and xf86-video-nouveau-git from the AUR for example) to see if it's been fixed since the official packages were released.

Re: nouveau and hdtv-out

Also, what about xrandr --addmode?

Re: nouveau and hdtv-out

that very well may work, but the problem i am having is that, i believe, the nvidia driver encodes or formats the video differently when component video out is forced with the xorg option.  when component video out is not switched on, the video has a blue tint.  but for the sake of trying everything, what would the correct parameters to add 1080i be for --addmode?  i understand that it is 1920x1080i, but how do i get it to do the interlacing?  thanks for the help, guys.

1920x1080x30?  I'm not actually sure.

Re: nouveau and hdtv-out

Try this:
1)

gtf 1920 1080 30

This is in order to generate the desired modline. Replace 30 with the desired refresh rate.
2)xrandr --newmode the_output_of_gtf. This is in order to create the modline for xrandr
For example:

xrandr --newmode "1920x1080_30.00"  80.18  1920 1984 2176 2432  1080 1081 1084 1099  -HSync +Vsync

3) Assign the new mode to your tv in xrandr:

xrandr --addmode DVI1 1920x1080_30.00"

Replace DVI1 with your actual tv device and then try to switch to that new mode.
