Laptop and TV-out issue with Intel chipset
 
I've got a Laptop with Intel video chipset. I've got a full slackware 13.37 installation and I'm using the huge-smp kernel all though it's not recommended. But I don't think the issue is kernel related.

The problem is that it detects that there is a monitor connected to the s-video connector, but there is no picture on the screen. It doesn't matter what mode I use, but ideally I want cloning.

What happens when I use KDE and krandertray (or system-configuration for that matter) is that I can choose resolution and everything but no picture shows up on the TV.

When I press the "Identify monitor" (Or something) button both the "1 TV1" and "2 LVDS1" shows up on the same monitor (laptop). That is weird.

Has anyone experienced anything similar or could point me in some direction as to what could be done?

(I haven't had the chance to test modifications to xorg.conf quite yet, but I guess that should work. However, I think it's worth it to get rid of this bug)

I'm starting to think this might be a Xorg/kernel/driver problem after all.

I've tried to configure xorg manually using the intel man-page, and used a modified version of their example. Running Xorg -config <custom xorg.conf> from TTY1 directly starts a black screen (as expected) on the laptop, but doesn't even make the television flicker. No errors are produced and the resulting log-file shows that the television is detected, but doesn't give any errors.

I'm quite lost actually. Would it be appropriate to file a bug-report to the Intel developers? I can upload the custom xorg and log file in a little while if someone should be interested in them.

Strong words. :)

I've done some more research and I fail to see what's wrong. Summarized, I think the issue is laying in one of these lines:

Code:
[  4410.348] (--) PCI:*(0:0:2:0) 8086:27a2:1025:0094 rev 3, Mem @ 0xb0080000/524288, 0xc0000000/268435456, 0xb0040000/262144, I/O @ 0x00001800/8
[  4410.348] (--) PCI: (0:0:2:1) 8086:27a6:1025:0094 rev 3, Mem @ 0xb0100000/524288
[  4410.409] (II) intel(0): Output TV1 has no monitor section
[  4410.363] (II) intel(0): Integrated Graphics Chipset: Intel(R) 945GM
[  4410.363] (--) intel(0): Chipset: "945GM"
These are from Xorg.0.log. Could one solution be that I need to specify a BusID for the PCI: (0:0:2:1) thingy? And how would I do that? I've tried some combinations in xorg.conf but it doesn't seem to make a difference.

I don't know why it says that TV1 has no monitor section, because it has. I made the xorg.conf using the man-pages for xorg.conf and intel. However, it detects the chipset as 945GM, while this is a Intel GMA 950. Would they be compatible?

I haven't configured a clone view now, but as a debuging mode, I only try to get a picture on the TV. For the interested reader, here is the relevant parts of my configuration and log-file:

Code:

And the log file. Things that I know isn't relavant is cut away. Things I think is highly relevant is highlighted.

First, have you tried without any xorg.conf? I find that my 945GME does not require it.

My thoughts on your xorg.conf to achieve a cloned display. Blue denotes alterations and additions. Red denotes deletions.
Code:
Section "ServerLayout"
        Identifier    "X.org Configured"
        Screen      0 "Screen0" 0 0
        Screen      1 "Screen1" 0 0

        InputDevice    "Keyboard0" "CoreKeyboard"
EndSection

Section "Module"
        Load  "extmod"
        Load  "dbe"
        Load  "glx"
        Load  "record"
        Load  "dri2"
        Load  "dri"
EndSection

        Identifier  "Card0"
        Driver      "intel"
        Screen      0
        Option      "monitor-LVDS1" "Monitor0"
        Option      "monitor-TV1" "Monitor1"
EndSection

        SubSection "Display"

EndSection

Thank you for looking through my file.

I have tried without xorg.conf, but with no success. I tried your modifications as well, but still no flickering or picture on the television. However, this now appeared in the log file:

[ 459.433] (II) intel(0): Output TV1 using monitor section Monitor1

So that's a great leap. Thank you :)

Tomorrow night I will try the kubuntu live CD. That works with clone view so I will see what driver gets loaded and what version is used. I will, if I find out how, downgrade drivers to see if I'm in luck.

Dinithion 07-28-2011 11:28 AM
No luck. The good news is that your modifications "works". I started a kubuntu live CD, and your xorg.conf worked perfectly. However, still no picture in slackware. I tried downgrading the intel driver, without luck. Xorg wouldn't discover the new driver.

I think I found the cause though:

CH7xxxx DVO TV-out not supported (Chrontel specs are open so anyone could write the driver): bug#12882.
Textured video is not available on i8xx.
I'm not sure if I've got a CH7xxxx chipset(*), but I guess I have. It's weird that it works in kubuntu though. Oh well I'll just install kubuntu to get it working. I don't feel like spending hours on end to try and fix it. This laptop is permanently connected to the TV, so no TV-out is quite useless. :(

But thanks anyway. And people are still welcome with suggestions. I'll probably wait a day or two before installing kubuntu in case someone gets a brilliant Idea :)

(*) Edit: Everything else in my computer has a Chrontel chipset, so it seems likely that video chipset is Chrontel as well.

Edit 2: Got an older driver to work, but still no picture.

This suggests the problem is in the kernel. Seemed to appear after 2.6.35 and is fixed for some people in 3.0-r2.

Dinithion 07-29-2011 07:17 AM
YES! You're the Google champion!

I can't believe after hours of googling that I didn't find that discussion. Anyway, thank you so much, it works like a charm.

I'm now using the 2.6.34.10 kernel, I'm a little skeptical about 3.0 just yet.

Again, thank you. :D
