There seems to be two problems in your Xorg.0.log. First, it doesn't find any connected monitors (even though you have one one the HDMI connection) and then after it has already given up there is a crash. Let's focus on the HDMI connection for now.

First, I would like you to try the intel drivers from https://launchpad.net/~ubuntu-x-swat/+archive/x-updates/ . With these you may need to add the line
  AccelMethod "uxa"
to the "Device" section of your xorg.conf.

 I see that you have tried the karmic package xserver-xorg-video-intel_2.7.99.1+git20090602.ec2fde7c-0ubuntu2_i386.deb. Mixing Jaunty and Karmic packages may have some unintended consequences, so I would rather recommend that you test out a full installation of Karmic, or use the xorg-edgers archive which has the very newst drivers compiled for Jaunty: https://launchpad.net/~xorg-edgers/+archive/ppa.

Could you try some of the suggested options, report the result here and upload Xorg.0.log for that run. It would be nice if you could include the line
  Option "ModeDebug" "true"
in the device section of you xorg.conf, since this will add additional information to Xorg.0.log.

[Robin Zhang (robinzt)]

I have tried: xserver-xorg-video-intel_2.7.1-0ubuntu1~xup~1_i386.deb from https://launchpad.net/~ubuntu-x-swat/+archive/x-updates/.
But it is still failed to find my monitor.

[Geir Ove Myhr (gomyhr)]

It would be nice if we could get this upstream, and let them see if they can find the problem. There is some more information we would like to be able to file a good upstream bug.
- If possible, test with a recent version of the driver. Right now, this is pretty easy, as the Karmic Daily LiveCDs now are working: http://cdimage.ubuntu.com/daily-live/ (there should also be an alpha-2 soon). If you could confirm that it is still a problem there and upload the resulting Xorg.0.log with ModeDebug enabled, that would be perfect.

Otherwise, you it looks like you have provided all the information they want upstream, but it would be great if you could take a look at http://intellinuxgraphics.org/how_to_report_bug.html and provide any information that you haven't already. I don't think the output of dmesg should be necessary for this kind of bug, but I guess it doesn't hurt.

Report bugs to upstream:

https://bugs.freedesktop.org/show_bug.cgi?id=22189

[Geir Ove Myhr (gomyhr)]

Robin, thanks for filing the upstream bug report. It would be nice if you could also test with a Karmic LiveCD (on a USB stick if you would like) and report the result and Xorg.0.log with ModeDebug enabled upstream. Karmic has a very recent development version of the driver (from June 2nd) and I think the upstream developers would appreciate a confirmation with a recent driver. Alternatively you may use Jaunty with the xorg-edgers repository, but I think that is more of a hazzle.

[Geir Ove Myhr (gomyhr)]

Robin, there is a patch upstream that you may test. If you are not comfortable with building packages or simply want to save some time I have built two sets of packages for you and put them at http://www.kvante.info/LP384660/ . You will need use the xorg-edgers PPA to use it (https://launchpad.net/~xorg-edgers/+archive/ppa), since there are some dependencies from there. If you don't want to install it to you computer, it should be possible to use a Jaunty LiveCD and the xorg-edgers-live-test script.

You will probably not need the -dbg packages. There are two versions of the packages:
* xserver-xorg-video-intel_2.7.99.901+git20090610.9d3c3b05-0ubuntu0sarvatt~jaunty_i386.deb
This should be the same as the one in the PPA right now. I just included it so that you can test two packages that are built in exactly the same environment so that the applied patch is the only difference.
* xserver-xorg-video-intel_2.7.99.901+git20090610.9d3c3b05-0ubuntu1gomyhr~jaunty_i386.deb
This is the latest package from the PPA, but with the upstream patch from
http://bugs.freedesktop.org/attachment.cgi?id=26664&action=edit included.

If the patch works, the first package should not detect your HDMI monitor, while the second should.

[Robin Zhang (robinzt)]

Thanks Geir Ove Myhr.

I will try your package later.

[Robin Zhang (robinzt)]

Yes, the "sarvatt" version cannot work, but "gomyhr" (patched) version can detect my TV and can set resolution to 1360x768 @ 60Hz.

 xrandr report:

Screen 0: minimum 320 x 200, current 1360 x 768, maximum 1360 x 1360
VGA disconnected (normal left inverted right x axis y axis)
HDMI-1 connected 1360x768+0+0 (normal left inverted right x axis y axis) 820mm x 460mm

freedesktop 22189 was marked duplicate of 21322. Updated the bug watch.

[Bryce Harrington (bryce)]

According to the upstream bug report, this is now fixed upstream via a patch to the kernel drm code, so I'm reassigning to the kernel.

    drm/i915: hdmi detection according by reading edid

    According to investigations from windows team ,hw team,
    and our test results on all 4x platofrms available
    (gm45, g45b, q45, g45a, g45c, g41a, and g41), we find
    currently Hot plug live status and Hot plug interrupt
    detection are not reliable, sometime the results from
    the two approaches are contradicts. So we chose edid
    detection for hdmi output.

When will this fix be availiable in Ubuntu 9.10?

[Leann Ogasawara (leannogasawara)]

This should already be in Karmic (see commit below). Marking this Fix Released.

Well I now have Karmic, but I still cannot get my DVI ports to do anything. They still show up as HDMI.
My current kernel is 2.6.31-7-generic #27-Ubuntu SMP

[Casandro (casandro-lion)]

Well now the bug has changed for me, xrandr now gives:
Screen 0: minimum 320 x 200, current 1280 x 1024, maximum 8192 x 8192
VGA1 connected 1280x1024+0+0 (normal left inverted right x axis y axis) 337mm x 270mm
   1280x1024 60.0*+ 75.0
   1024x768 75.1 70.1 60.0
   832x624 74.6
   800x600 72.2 75.0 60.3 56.2
   640x480 72.8 75.0 66.7 60.0
   720x400 70.1
DVI1 disconnected (normal left inverted right x axis y axis)
DP1 disconnected (normal left inverted right x axis y axis)
DVI2 disconnected (normal left inverted right x axis y axis)
DP2 disconnected (normal left inverted right x axis y axis)

When one monitor is connected to the DVI-I output (via an VGA Adapter) while the other is connected via DVI. The DVI one does not work.

[Geir Ove Myhr (gomyhr)]

Casandro, since you still have a problem, you probably don't have the same bug as the original reporter (Robin Zhang), even though you may have the same symptoms. In such cases you should file your own bug report instead of commenting here.

[Casandro (casandro-lion)]

Ohh sorry, I guess we can close the bug now. It was the monitor, it IDed it self incorrectly It works with another monitor.
