    Default TV-Out Lucid - Output S-video disconnected

    Hi all, I had s-video working great (well svideo to composite adapter) in karmic but trying out the new mythbuntu beta I can't get it to work using the same xorg.conf
    I'm not getting any output to the tv at all, playing with xrandr gives no errors but doesn't help

    original (worked in karmic xorg.conf)

    load detection has always been flaky on XPRESS chips and as such is disabled by default. You can force load detection (and try and detect the output) or the actual connector on using xrandr.

    Thanks agd5f, adding option "enabled" true to the monitor section of xorg.conf worked getting zaphod going.

    Now just if dri worked in zaphod mode I'd be set, for now the old xorg.conf will have to do.

    I'd love to get zaphod fully working so I can have mythtv on its own screen without hacking around with a windowed size and the aspect is messed up because its counting the whole virtual resolution and such.

    zaphod log in case anyones interested

    wierd mythfrontend.log when running in zaphod mode with dri obviously disabled

    DRI with zaphod requires kms.

    hmm after fooling around with xorg.conf I cannot seem to get zaphod working with kms enabled. This time the s-video is enabled but no modes are found despite me defining them in monitor and screen.

    Well KMS doesn't want to play nice, after fooling around with different xorg.conf configs it seems to always return with the following error. The laptop screen is on but the tv-out isn't enabled.
    I tried using the xorg-edgers ppa with newer drivers but that didn't seem to make any difference.

    Is this a bug or do I just suck at tweaking my xorg.conf?
    Here is the zaphod xorg.conf that I can use with KMS off.

    I've got simmilar problem with KMS and S-video.
    On my Lucid installation S-video gets disabled at boot time on KMS because of DAC encoders conflict:

    Do you know how to enable S-video even in clone mode of DVI output?
    Forced load_detection option doesn't enable it as it did on UMS - xrandr always tells it's disabled.

    Btw, agd5f, could you please take a look at my GL problem on the second head (RV370 card) - I get no errors with glxinfo or glxgears output but glxgears works good only for 1-2 seconds, then my desktop freezes from one to few seconds, then 1-2 seconds of glxgears working OK and so on...
    my primary post with logs
    I wonder if the line:
    [ 1.399922] radeon: No suitable DMA available.
    has anything to do with this problem.
    I've tried to mix some video related settings in BIOS but it didn't help either.
