Binary package hint: xorg

xorg crashes with 9.10 and ubuntu-bug and uing ppa is also not working. Says network fault in the only shell available. But apt-get is working.

Hi Arun,

Please attach the output of `lspci -vvnn` and `dmesg`, and attach your /var/log/Xorg.0.log (and maybe Xorg.0.log.old) file from after reproducing this issue. If you're using a custom /etc/X11/xorg.conf please attach that as well.

[This is an automated message. Apologies if it has reached you inappropriately; please just reply to this message indicating so.]

[Arun S L (arun-sl)]

finally did one tweek to get it working...

:-)

moved /lib/tls/i686/cmov/libc.so.6 out

ldd picked /lib/libc.so.6 and bingo... everything is working fine now...

Please let me know if there is a factual solution down the line.

[Julien Cristau (jcristau)]

sigill in memcpy sounds like a libc bug to me. closing as not our bug.

[Bryce Harrington (bryce)]

Arun S L - I've forwarded this bug upstream to http://bugs.freedesktop.org/show_bug.cgi?id=27436 - please subscribe yourself to this bug, in case they need further information or wish you to test something. Thanks ahead of time!

[Bryce Harrington (bryce)]

Upstream believes this to be a bug in libc, not X.org. Reassigning to libc

[Kees Cook (kees)]

Can you attach the contents of your /proc/cpuinfo file? It seems like glibc is choosing the wrong library for accelerated memcpy maybe?

BTW, instead of building your own glibc, consider using the existing debug symbols for the regular eglibc build in Ubuntu. See https://wiki.ubuntu.com/DebuggingProgramCrash for details.

[Matthias Klose (doko)]

Please could you check an eglibc built without --enable-multi-arch?

  deb http://ppa.launchpad.net/doko/ppa/ubuntu lucid main
  deb-src http://ppa.launchpad.net/doko/ppa/ubuntu lucid main

[Matthias Klose (doko)]

it's not in glibc. there's already an eglibc task open

[Bryce Harrington (bryce)]

doko, explain why you set this back to xorg-server? Upstream does not believe it to be an xserver bug.

[Matthias Klose (doko)]

@bryce: we are using now eglibc for over nine months. this has nothing to with glibc.

[Bryce Harrington (bryce)]

doko, it's been determined already this is not an xorg-server issue so no task needs to be open against xorg-server.

[Shaved Wookie (shavedwookie)]

I'm getting this on a machine with: Kubuntu Lucid AMD 64, Radeon HD 4850 running ATI driver.

Lucid Beta 2 live cd works fine, but my installed version (which worked fine a few weeks ago until I updated recently) gets to KDM and then just stops. Mouse and Keyboard don't *seem* to respond, however Alt+SysRq+RSE drops me to a working root shell.

The only real uncommon errors I can see in kdm.log / Xorg.0.log are:

"Kcrash: Application 'KDMgreet' is crashing..."

and shortly after:

"Error setting MTRR (base = xd0000000, size = 0x100000000, type = 1) Inappropriate IOCTL for device (25)"
DDXSigGiveUp: Closing Log
drKonqi: cannot connect to X server 0.0"

Please let me know if there's any info I can provide to help.

[Shaved Wookie (shavedwookie)]

Just remembered... Two details that may / may not be important:

1. I boot with radeon.modeset=0 as I just get a black screen otherwise
2. This machine is also running xorg-edgers ppa

I understand that xorg-edgers is unsupported, but thought it worth adding in case the original poster was using X-E as well.

[David Leonard (david-leonard)]

Similar problem with fresh install of ubuntu desktop 10.04/i386 under VMware Workstation 5.0.0-13124;
X would just keep crashing out (even with failsafe/vesa) with :

  Illegal instruction at address 0xb76c1ca3
  Caught signal 4 (Illegal instruction). Server aborting

Workaround/solution was to move /lib/tls/i686/cmov/libc.so.6 out of the way.

That library owned by: libc6-i686 (2.11.1-0ubuntu)

gdb session of "X -once :0":

[Jan Van Sanden (lambdacore)]

I also got this Bug.
Fresh install of 9.04 in a VM under ESX 3.5, then upgrade to 10.04.

gdm kept crashing until I renamed /lib/tls/i686/cmov/libc.so.6 to /lib/tls/i686/cmov/libc.so.6-old so it is no longer used.

Thus I can confirm the workaround in comment #10 as working.

[volinthius (volinthius)]

I'm experiencing this bug as well. Running Lucid on Hardy's qemu (0.9.1-1ubuntu1).

Renaming /lib/tls/i686/cmov/libc.so.6 away bypassed the bug.

[Arun S L (arun-sl)]

status: Confirmed → Won't Fix
What does this mean? Every time there is a tls update, i need to manually

cp /lib/libc.so.6 /lib/tls/i686/cmov/libc.so.6 by booting from CD?

There is no way out yet.... !

[Arun S L (arun-sl)]

Maverik the problem is even worsened!!

/lib/libc.6.so is itself effecting the crash!

[Arun S L (arun-sl)]

Sorry for being late to respond.

missed the question amidst other comments

the cpuinfo file asked is being attached

[Chris Halse Rogers (raof)]

This appears to be a eglibc bug, not an Xserver bug. Closing the Xserver tasks.

Has anyone actually answered Doko's question -
“
Please could you check an eglibc built without --enable-multi-arch?

  deb http://ppa.launchpad.net/doko/ppa/ubuntu lucid main
  deb-src http://ppa.launchpad.net/doko/ppa/ubuntu lucid main
”

[Jan Van Sanden (lambdacore)]

Just tried to install 10.04.2 LTS (32bit, desktop) from scratch in a newly created virtual machine running on a VMware ESX server.
xserver kept crashing until I deleted file /lib/tls/i686/cmov/libc.so.6
Only then I was able to install via restarting gdm.
So this bug is still relevant and prohibits installation for the unsuspicious admin.

[Arun S L (arun-sl)]

I switched to virtualbox and there this issue is not bothering me anymore.

Maybe this is a glitch in VMWare itself ???

[Arun S L (arun-sl)]

Maybe we should open a thread for the issue with VMWARE as well.

After upgrading to 10.10 the workaround with removing /lib/tls/i686/cmov/libc.so.6 does not work anymore, as this file is no longer present. Instead the Backtrace reads as follows:

I'm also under the suspicion, that this may be a problem related to some incompatibilities between vmware and libc.so.6.
If you need more informations, just ask, the problem is absolutely reproducible with at least 6 different machines I'm running under different VMware ESX Servers versions (3.5, 4.0 and 4.1).

This is no more a supported version now
