x-server crashes on startup with intel GMA3000

Thank you for reporting this bug. Please add your xorg.conf and the Xorg.log.

I looked in /var/log/ for the xorg log.

As far as I can tell, its not writing anything there. There is an Xorg.0.log, but that comes from before the problem. When I try to start up the x-server now, as far as I can tell its not writing anything in /var/log/

is there somewhere else to look?

No, just go ahead and attach the /var/log/Xorg.0.log, that's the correct file.

Also, we will probably need a full backtrace. See http://wiki.ubuntu.com/X/Backtracing for directions on doing that.

When it crashes it does not produce and Xorg.0.log file.

Also, I've tried alt-SysRq (my kernel is set up for this) but it doesn't help with this crash.

I've tried running gdb from a remote terminal, I'll paste the output below. When I do that, it ends up hanging in the usual way. I've also looked around to see if its doing a core dump anywhere, but couldn't find one. (I did install xserver-xorg-core-dbg, and add the untrap signals lines to my xorg.conf).

Thanks for posting. Could you please add the line
Driver "vesa"
to your /etc/X11/xorg.conf Device section.
Maybe it is a hardware issue but Gutsy Live CD still works without problems?

Adding
Driver "vesa"
to xorg.conf does work. It allows X to come up. So this is good, though it doesn't give me all the choices of screen resultion I'd like.

In answer to your second question, no, the Hardy live CD does not work. It hangs.

Also, I just tried the live CD on a second computer with the same hardware setup, and this too hangs. (video card "Intel Corporation 82Q963/Q965 Integrated Graphics Controller").

So this is a problem with the driver for the intel card?

If the machine can't be reached over the network, then usually that means there has been a kernel failure. That it fails with -intel but not -vesa is a strong clue that the issue is video card related, but it could just be due to trying to use some feature of your hardware that -vesa doesn't support or something (e.g. DRI/Compiz).

The error message about no device for 0.2.1 is normal, it just means there wasn't a second monitor detected.

I'm going to bump this over to the kernel bug team to triage at this point.

Hi eb207,

As unggnu mentioned earlier, care to attach the output of 'sudo lspci -vvnn'.

You mentioned this does not happen with a Gutsy LiveCD and that you upgraded from Gutsy to Hardy. Do you by chance still have the Gutsy kernel available on your system. Would you be able to boot from the Gutsy kernel - might help narrow down that this is indeed a regression in the kernel. Also, just as a test, care to try testing with the Intrepid Ibex 8.10 kernel. It was most recently sync'd with the upstream 2.6.25 kernel and is currently available at the following PPA (personal package archive):

https://edge.launchpad.net/~kernel-ppa/+archive

If you are not familiar with how to install packages from a PPA basically do the following:

Add the following two lines to /etc/apt/sources.list

deb http://ppa.launchpad.net/kernel-ppa/ubuntu hardy main
deb-src http://ppa.launchpad.net/kernel-ppa/ubuntu hardy main

sudo apt-get update

You should then be able to install the linux-image-2.6.25 kernel package. Please let us know your results. This will indicate if the bug exists using the upstream kernel and where the kernel team will want to focus getting this resolved or pull the fix from. Thanks.

Thanks eb207,

Just wanted to add another quick note that actually rather than editing your /etc/apt/sources.list file it's probably safer to create /etc/apt/sources.list.d/kernel-ppa.list to include the lines:

deb http://ppa.launchpad.net/kernel-ppa/ubuntu hardy main
deb-src http://ppa.launchpad.net/kernel-ppa/ubuntu hardy main

It avoids possibly messing up the default repository settings that exist in /etc/apt/sources.list

Thanks.

It does look like a kernel issue.

I just booted with an earlier kernel:
uname -a
Linux parapithecus 2.6.20-16-generic #2 SMP Thu Jun 7 19:00:28 UTC 2007 x86_64 GNU/Linux

and it works. that is, i took the vesa line out of xorg.conf, and it doesn't crash this kernel.

I'll try it with that upstream kernel, probably tomorrow.

thanks!

I just tried X (without the vesa line) with the 2.6.25-1 kernel, and found that it also hangs.

I also have a modification to what I said about the 2.6.20-16. The first time I boot into that kernel, and startx, it works. However, if I log out, and try again, then it too hangs. (I'm not using gdm at this point. so by logging out, I go back to the console and then try startx again).

thanks.

Hi eb207,

Thanks for testing. When you're running the Intrepid kernel, would you be able to grab the dmesg output from that machine again? I just want to get the most recent log information we can. Thanks.

Here is dmesg running

Is this bug still being worked on? It's still broken on a fully updated Hardy as of August 12th.

My only workaround (other than using drivers which don't support my monitor's native resolution) is to boot into an older kernel (in recovery mode), run the X fixer, then reboot. Sometimes.. sometimes it works.

I think this bug is related to this https://bugs.launchpad.net/ubuntu/+source/linux/+bug/255961

The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the upcoming Intrepid Ibex 8.10 release. As a result, the kernel team would appreciate it if you could please test this newer 2.6.27 Ubuntu kernel. There are one of two ways you should be able to test:

1) If you are comfortable installing packages on your own, the linux-image-2.6.27-* package is currently available for you to install and test.

--or--

2) The upcoming Alpha5 for Intrepid Ibex 8.10 will contain this newer 2.6.27 Ubuntu kernel. Alpha5 is set to be released Thursday Sept 4. Please watch http://www.ubuntu.com/testing for Alpha5 to be announced. You should then be able to test via a LiveCD.

Please let us know immediately if this newer 2.6.27 kernel resolves the bug reported here or if the issue remains. More importantly, please open a new bug report for each new bug/regression introduced by the 2.6.27 kernel and tag the bug report with 'linux-2.6.27'. Also, please specifically note if the issue does or does not appear in the 2.6.26 kernel. Thanks again, we really appreicate your help and feedback.

This issue is still unresolved. Intel driver still hangs on my Dell Optiplex 745 on Kubuntu 8.04.1 with Ibex kernel. Using vesa driver as a workaround helps, but is not the solution :-)

Unfortunately it looks like the kernel team was unable to address this during Intrepid's development cycle. Can we just get confirmation this is still an issue with Intrepid's final release? Thanks.

I am NOT experiencing this issue any more with the release version of Intrepid Ibex.

I will also test tomorrow with a live cd of Intrepid and clean install. I will let you know how it went.

I have tested LiveCD with Intrepid and it seemed to be fixed there. I also checked the Intrepid alpha4 LiveCD to see if it was the kernel upgrade from 2.6.26 to 2.6.27 that did it, but I could also not reproduce it with alpha4.

In Hardy (32-bit, fully updated) it's still very much an issue, though. I can get around it by using the i810 driver, but that has other bugs.

I tested with ubuntu 8.10 live cd and can confirm this bug has been fixed.

Thanks. Marking as fix released.

Per a decision made by the Ubuntu Kernel Team, bugs will longer be assigned to the ubuntu-kernel-team in Launchpad as part of the bug triage process. The ubuntu-kernel-team is being unassigned from this bug report. Refer to https://wiki.ubuntu.com/KernelTeamBugPolicies for more information. Thanks.
