[i946GZ] - only output to vga not hdmi or dvi

[Jeremy Lucier]

Binary package hint: xserver-xorg-video-intel

I upgraded from Hardy to Ibex RC, and instantly hit a problem which I've been trying to solve for over 4 hours now. A little background, I have a 946GZ Intel gfx card, connected via HDMI to my Asus VK222H monitor (22" widescreen). Prior to the upgrade, it ran perfectly fine under Hardy with the Intel driver and it recognized all the resolutions properly, etc. Now, onto the problem:

Basically, upon gdm attempting to show itself (it doesn't), I receive the following errors from X:
- (EE) intel(0): No valid modes.
- (EE) Screen(s) found, but none have a usable configuration.

So, I figure my Xorg.conf is out of date. So I of course recreate the file using dpkg reconfigure, and the same occurs. I try setting the BusID and also hardcoding in which driver to use within the xorg.conf -- but still nothing. I've tried a few recommendations such as the procedures listed under the launchpad doc's, but still I haven't had any success.

Basically, the only way I can view GDM/Gnome/etc is by using the slower VESA driver.

Thanks for reporting this bug. For the sake of troubleshooting, could you try to connect your monitor using VGA and DVI if available? Also, although dpkg reconfigure should probably effectively do the same, could you remove your /etc/X11/xorg.conf alltogether? Finally, the developers like to have the output of lspci with the options -vvnn.

I haven't seen any other bugs for 946GZ yet, so there will probably not be many others who can confirm or help troubleshooting.

I attempted the connection using DVI with no success (it returns the same as it does under HDMI). I've also tried HDMI and DVI with no xorg.conf at all, and failed under both with the same errors.

I'll attempt the VGA when I get home (in around 3 hours) with the xorg.conf removed, and also after a dpkg reconfigure. I'll also grab the lspci -vvnn as well.

[Jeremy Lucier (jrlucier)]

Under VGA, the intel driver and X load properly. I've attached the Xorg.0.log for the VGA session.

[Jeremy Lucier (jrlucier)]

lspci -vvnn for VGA. - This does work.

[Jeremy Lucier (jrlucier)]

Xorg DVI file - Fails.

[Jeremy Lucier (jrlucier)]

lspci -vvnn for DVI

[Jeremy Lucier (jrlucier)]

Xorg HDMI - Original problem, fails.

[Jeremy Lucier (jrlucier)]

lspci -vvnn for HDMI

It looks like your DVI and HDMI connections are not detected (the logs for DVI and HDMI are identical). The driver doesn't see any connected monitors, and therefore doesn't know what to do. I think it should be possible to add stuff to xorg.conf to override it, but hopefully someone else knows exactly what. I think something along the lines of
Option "monitor-TMDS-1" "My DVI monitor"
in the Device section and then a section with something like
Section "Monitor"
        Identifier "My DVI monitor"
        ...
EndSection
where ... probably contains the modelines that you find in the Xorg.0.vga.works.log. If you want to dig a bit yourself you can check out the monitor section of the xorg.conf(5) man page.

[This is an automatic notice.]

We'd like to forward your bug upstream, however upstream requires
that you first test it against their newer driver code.

To save you the effort of building the driver from source, we've built
packages for the driver and its new dependencies.

So you have a couple options:

 1. Download and test .debs for intrepid, from:
     https://edge.launchpad.net/~intel-gfx-testing/+archive

 -or-

 2. Download and test the Jaunty alpha-2 (or newer) Live CD,
     (which includes a beta of the new xserver 1.6 as well).
     See http://cdimage.ubuntu.com/releases/9.04/ for ISOs

Thanks ahead of time! You can simply reply to this email to report your
findings.

P.S., if you wish to forward your bug upstream yourself, please follow
these directions to do so:
  http://intellinuxgraphics.org/how_to_report_bug.html

[Jeremy Lucier (jrlucier)]

I just tried option number 1 (installing the test debs) -- that did not fix the problem at all.

I'll attempt #2 tomorrow. :)

Hello
I have the same problem for using Sony VPL-ES5 LCD Projector, I'm using ASUS P5GC-VM PRO mainboard with onboard Intel® 945GC Chipset I also tried GIGABYTE GA-G31M-S2L with the same Graphic chip and I've had same problem.
I atached the xorg log file.

[Iman (ghasrfakhri)]

In addition I have only VGA output.

[Bryce Harrington (bryce)]

Thanks for the confirmation. Guess this can go upstream now.

[Bryce Harrington (bryce)]

@lman, you have a completely different video card model, not appropriate to this bug report. You should report it as a separate issue as we will not be investigating it as part of this bug. See http://wiki.ubuntu.com/X/Reporting for directions on reporting X bugs.

[Bryce Harrington (bryce)]

jlucier, I've forwarded your bug upstream to https://bugs.freedesktop.org/show_bug.cgi?id=19548 - please subscribe to this bug in case upstream needs further information or wishes you to test something. Thanks ahead of time!

[Bryce Harrington (bryce)]

jlucier, upstream has asked to see the Xorg.0.log from your test with the newer driver, as they believe it should work with that.

Also, have you had a chance to test against jaunty? That could also be useful in case the newer xserver plays a role in this.

[Jeremy Lucier (jrlucier)]

Here's the Xorg.0.log with the newer driver's installed.

[Jeremy Lucier (jrlucier)]

Just tested with Jaunty [Alpha 3] -- same exact problem/issue.

[Bryce Harrington (bryce)]

Jeremy, upstream would like you to join the upstream bug report for further discussion of this issue. Please join it via https://bugs.freedesktop.org/show_bug.cgi?id=19548, otherwise they may close it due to lack of information rather than continue investigation of your issue.

[Jeremy Lucier (jrlucier)]

Joining the bug report upstream. Attached is the latest Xorg.0.log from boot up (before reverting back to vesa).

[Jeremy Lucier (jrlucier)]

Here's the latest Xorg.0.log with debugmode set to true.

[Bryce Harrington (bryce)]

Looks like this was fixed as of the 2.7 release, which is available in karmic now, and in the x-updates ppa for jaunty. Closing as fixed.
