xorg output
Ok, so it looks like VGA and DIN share DAC2; this is usually wired the other way around for most oems. So you do need the DVI to VGA adapter to use TV and VGA. Can you attach your xorg log with ums? No need to compress attachments.

This might be a dupe of bug 29985. Make sure your kernel has this patch: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=54bfe496cec7586f76f713a277435dd3ac6fd4c4 I checked 2.6.36-rc5 (it contains this patch as I understand). Have no improvements yet. Created attachment 39028 [details]
connected TV when it rarely works
I attach xrandr output when TV works with KMS (it happens rarely). If I do --off TV then it reports disconnected. Then I do: $ xrandr --newmode tv 133.5 1024 1100 1212 1400 768 768 770 794 $ xrandr --addmode DIN tv $ xrandr --output DIN --mode tv $ xrandr --output DIN --set 'load detection' 0 but output does not work after that. works for me now. was fixed by kernel parameters: radeon.modeset=1 video=DVI-I-1:1280x1024-24@60e video=DIN-1:1024x768-24@60e or radeon.modeset=1 # video=DVI-I-1:1280x1024-24@60e "video=9-pin DIN-1:1024x768-24@60e" |
