Hello i hope this is the right place to ask a question about the s-video out using the new intel driver on an i810 chipset. Im running gusty with the intel modesetting branch and am trying to configure the s-video for connection between my computer and tv. When i run randr it doesnt even detect my tv connected...
Screen 0: minimum 320 x 200, current 1024 x 768, maximum 1024 x 1024
VGA disconnected (normal left inverted right)
LVDS connected 1024x768+0+0 (normal left inverted right) 0mm x 0mm
1024x768 59.3*+ 85.0 75.0 70.1 60.0
800x600 85.1 72.2 75.0 60.3 56.2
640x480 85.0 72.8 75.0 59.9
Is there support for s-video in the new modesetting driver for the i810 chipset? or planned to make support for it or am i having an error? Hope u understand what i mean.
You should use master branch not modesetting branch for intel driver. (modesetting branch has been dead and merged to master.)
I can see TV output with s-video on 915GM chipset. Is your i810 integrated with s-video, or through ADD card?

Oh sorry i probably use the master branch, kinda new to this, the one that comes with the ubuntu gutsy I pressume is the master branch. My i810 is integrated with s-video. IBM thinkpad R51.
Could you double-check if it's i810 by command "lspci"? I thought R51 is 855GM.
Please attach Xorg.0.log.

Your are correct, im sorry for posting a bad bug, really sorry.
The lspci shows
Intel Corporation 82852/82855 GM/GME/PM/GMV
Really appreciate your fast answers!
Xorg.0.log is in attachment
We currently don't support any TV out through DVO, which is what your laptop uses. The usual chips (chrontel) have published specs which could be used to write an appropriate DVO driver, and we have several LVDS and TMDS DVO drivers already in the tree that could be used as examples.
mark as wontfix..
Just because intel's not planning on writing these drivers at the moment doesn't mean that the issue is irrelevant. We all agree that having these drivers would be good, while "wontfix" usually means that the upstream maintainers don't want to see the issue fixed.
Leave this to community.
*** Bug 18274 has been marked as a duplicate of this bug. ***
In order to see a video from my HD I have to do the following things:
1) copy video to Windows XP NTFS partition
2) reboot into Windows XP
3) enable DVO
It would be VERY USEFUL to me to have this DVO output working from Linux, I would completely remove Windows XP and no more need it to see my videos...
*** Bug 19322 has been marked as a duplicate of this bug. ***
If this bug is duplicate of bug 18274, then please update the summary: this is not a Thinkpad R51 issue but an Intel 855GM issue (with 'intel' driver).

Xorg.0.log from V.Pagliari http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=493096
A working TV-OUT with 'intel' driver and i855GM chipset, please notice the following lines in attached log:
(II) intel(0): I2C bus "DVOI2C_E" initialized.
(II) intel(0): I2C device "DVOI2C_E:SIL164 TMDS Controller" registered at address 0x70.
(II) intel(0): Output TMDS using monitor section GH19PS
Can we say that problem is in the missing DVOI2C_E + SIL164 initialization?
Some pipe problem?
Created attachment 21803 [details]
my "grep intel\(0\) /var/log/Xorg.0.log"
This guy had a similar problem with LCD being disabled:
Note the same pipe error: FIFO_UNDERRUN VSYNC_INT_STATUS VBLANK_INT_STATUS
The thread contains no solution to the problem, except a hint about the 'intel' driver being the guilty one.
In attachment 21306 [details] we can see another case of TMDS being detected, even if not used.
Can we reduce our problem to TMDS not being detected?
How is it that it is detected on that hardware?

I think I am affected by the same bug on 82830 CGC (pci=8086:3577) ...
I can help to build and test some experimentals versions...
Also I wish I can test latest iegd from intel to compare , but i can't find where to download it...
Tracking at : http://rzr.online.fr/q/stb
@www.rzr.online.fr: I am available for testing experimental versions of the driver. I have an 855GM chipset.
I have read your page but cannot find a proper version to test.
Pushed by frustration of having to close my Linux sessions and boot into Windows, I packaged a chroot live system to use my TV-OUT without rebooting.
Xorg 1.4 + the old i810 driver (v1.7.2) are inside, with perfectly compiling sources.
I hope this will be useful to some of you.
All feedback is welcome (on the SF.net project please)
What is the status here? AIUI dvo, and the sil164 chipset reference here, are supported so are the TV paths hooked up?

It doesn't work, Intel doesn't support it and nobody fixed the driver. There have been attempts to fix the driver by various people, with some results, but absolutely nothing for the (KMS) i915 intel driver.
Just dead hardware in our boxes
Have you had a chance to look at the alternate sil164 driver that is now upstream? Just in terms of removing code duplication I'd like to remove dvo_sil164.c. However considering they are almost identical and the comments in intel_dvo.c, DVO itself needs quite a bit of love first.

I have looked at the intel_dvo.c file and it looks like easy, however my hardware (i855GM rev02) uses the Chrontel70xxx chipset, not SIL. Shall I start from the staging ch7006 driver instead?
I'd suggest looking at these release news:
There is one significant line by Eric Anholt:
Disable TV/VGA output on the CH7017/7018 devices.
I think the i855GM TV-OUT was left for dead there. There is currently a ch7017 and ch70xx driver for DVO, but I am getting a bit confused so I don't know if my hardware has a DVO or a TV-OUT (it has a VGA output and a 5pin S-Video output), I'd say the TV-OUT (S-Video output) is the part dismantled in current driver.
This issue is affecting a hardware component which is not being actively worked on anymore.
Moving the assignee to the dri-devel list as contact, to give this issue a better coverage.
Reassign back to the public - this needs somebody with the motivation and hw to write the corresponding dvo driver.
Mass-closing missing dvo driver bugs. We won't ever do that, so this needs a RE effort from someone else.
