[i945] shuttle X50/intel 945 "No outputs definitely connected" (needs intel 2.7.1)

[Arsinio]

Binary package hint: xserver-xorg-video-intel

Using a Shuttle X50 with built-in monitor.

When starting X, it falls back to failsafe mode using VESA. From the best I can tell, X can't tell there is a monitor attached. I thought it might be an EDID problem with the monitor, but `get-edid` seems to reporting the monitor just fine.

[Geir Ove Myhr (gomyhr)]

This problem seems to be because of your xorg.conf. I'm not sure if it is a misconfiguration or if the driver is misenterpreting it. Anyway, what happens if you remove/rename your xorg.conf?

[Geir Ove Myhr (gomyhr)]

Also, please upload the output of the command `lspci -vvnn` as an attachment (not in the comment itselft).

[Arsinio (arsinio)]

Geir,
Thank you for your response! I'd venture to say there is an underlying problem somewhere, the ubuntu installation CD couldn't start X properly either, and fell back into safe mode. I wound up installing in text mode thinking there was just some configuration file tweaking needed...

Here is the output of trying to start without an xorg.conf

[Arsinio (arsinio)]

Here is the output of lspci -vvnn:

[Geir Ove Myhr (gomyhr)]

You're right, this is not about the xorg.conf. For some reason, the driver only checks the VGA connection, and does not find anything there. Normally, built in monitors are connected via an LVDS connection. In this case, the chipset is a 945G (not 945GM - which is the mobile version normally used in laptops). I haven't seen a computer with a non-mobile intel chipset and and a built in monitor before[*].

I wonder if the monitor is connected using LVDS, but since the driver sees that it is a non-mobile chipset, it simply assumes there is nothing there (I'm not even sure if the non-mobile chipsets have LVDS possibility, but let's assume it has for now). In this case, the telling the driver explicitly to use LVDS may help. If this is the case, we may quirk the driver to do this for this particular computer.

First, I would like you to add a minimal xorg.conf by running `dpkg-reconfigure -phigh xserver-xorg` and then add the line
Option "ModeDebug" "true"
to the "Device" section (or you can get a ready-made file from http://launchpadlibrarian.net/26665729/xorg.conf).
This will add a lot of extra information to Xorg.0.log the next time you start. Please upload this Xorg.0.log.

Next, I would like to know if the log from the failsafe session tells us anything interesting. By adding the line
  Driver "vesa"
to the "Device" section of xorg.log, that should use the generic vesa driver which is the same as what the failsafe option does. Please also upload the log for this case.

Finally, try to enable the LVDS explicitly in your xorg.conf. I'm not very familiar with the details for how to do this, but I guess following the "Ignore LVDS Quirk" at
https://wiki.ubuntu.com/X/Quirks#Ignore%20LVDS%20Output%20Quirk
should give the basic syntax, except that instead of
Option "Ignore" "True"
you should use
Option "Ignore" "False"
As I said, I'm not sure this is the right way to do it but hey, it just might work. If it does, it should be possible to add a quirk to the driver.

[*] Usually the problem is the other way around: A mobile chipset is used in a PC without a built-in monitor on the LVDS, and the driver implicitly assumes that all mobile chipsets have something attached to their LVDS.

[Arsinio (arsinio)]

Here is the log from the minimal xorg.conf with the 'Option "ModeDebug" "true"':

[Arsinio (arsinio)]

Here is the log from the minimal xorg.conf with debug and the driver set to VESA. An interesting thing to note is that the VESA driver does detect the monitor correctly and displays the EDID information in the log file...

[Arsinio (arsinio)]

Here is the log from explicitly enabling LVDS...no luck there either, in fact, I don't really see anything in the log file to indicate that it did anything different at all. Could this option possibly only be enabled for the mobile chipsets?

On a side note, I really appreciate your effort and fast responses!

[Geir Ove Myhr (gomyhr)]

I can't find anything in those logs that tells me what is going on. I think we should report this upstream. To make sure it is not something they have fixed already, you should test a newer driver. If it is still there, we report it upstream with the logs from the newer drivers. You have two options:
1. You can test the 2.7.1 driver from the x-updates PPA (Personal Package Archive) at https://edge.launchpad.net/~ubuntu-x-swat/+archive/x-updates/ . This PPA contains updated stable drivers that were released too late to get into jaunty. These packages solve a number of problems, but has a small chance of introducing new ones.
2. You can test the latest driver from the GIT master respository. This is the development version of the driver, and you can get it from the xorg-edgers PPA at https://launchpad.net/~xorg-edgers/+archive/ppa (see also info on https://launchpad.net/~xorg-edgers). This has a much higher chance of breaking something, is maybe a bit more complicated, but will probably make the intel developers a little more happy.

If you can test one of these and upload the Xorg.0.log if it does not fix things, then I can file the bug report upstream. I will then ask you to subscribe to it too in case the intel devs have questions or possible workarounds. You may also file the bug upstream yourself if you want to give it a try. There are instructions at http://intellinuxgraphics.org/how_to_report_bug.html. If you file it yourself, I will subscribe to the upstream bug and be able to help you with any questions.

[Arsinio (arsinio)]

Looks like your first recommendation fixed it! I added the package archived, downloaded the 2.7.1 driver, and everything seems to be working. Here is the xorg.0.log:

Thanks for your help!

[Geir Ove Myhr (gomyhr)]

I'm glad 2.7.1 solved the problem. Let's not send it upstream then ;-)

[Bryce Harrington (bryce)]

We've got newer than 2.7.1 in karmic now, so we can consider this solved in development.

[chrisisbd (chris-isbd)]

I have this problem and, for me, it *isn't* fixed by the 2.7.1 drivers.

Here is the relevant section from my Xorg.0.log file:-

... and I do have version 2.7.1:-

chris$ apt-cache showpkg xserver-xorg-video-intel
Package: xserver-xorg-video-intel
Versions:
2:2.7.1-0ubuntu1~xup~1 (/var/lib/apt/lists/ppa.launchpad.net_ubuntu-x-swat_x-updates_ubuntu_dists_jaunty_main_binary-amd64_Packages) (/var/lib/dpkg/status)

My system works because (as described in the first report) the first gdm/X using Intel fails completely on console 7 and I get a second one using the vesa drivers on console 9 which works OK (but no Intel acceleration etc.).

Is there anything I can do to help debug this problem and/or any workarounds?

My motherboard is an Asus P5Q-VM with on-board Intel G45/G43 chipset.

[Ned Taylor (entaylor)]

I had the same problem, and again it wasn't fixed by the 2.7.1 driver.

I had my monitor connected to a KVM switch which was connected to the video output on my machine. I discovered (by accident) that when the monitor was connected directly to the machine the problem went away. The problem turned out to be the cable from the KVM to the machine. When I replaced it everything worked fine. What's weird is that the old cable worked fine for everything else, and once I had started up, I could replace the new cable with the old and everything continued to work fine.

Anyway, I'm now back in business.
