[karmic] Xorg (and anything GLX) crashes on startup

[Pauli Virtanen]

As of after updates at 2009-09-13 ca. 16:00, Xorg and anything using GLX (eg. glxinfo) crashes on startup.
The only thing that seems to have been changed then is the upgrade of libc6 to 2.10.1-0ubuntu11.

Log of crashing Xorg run is attached. The corresponding gdb backtrace is:

[Pauli Virtanen (pauli-virtanen)]

Switching to the "nv" driver, and uninstalling nvidia-glx-185 makes glxinfo and Xorg not crash any more, so it seems this problem is localized to the non-free drivers.

[Pauli Virtanen (pauli-virtanen)]

Also, as expected, downgrading libc6 and libc6-i686 to 2.10.1-0ubuntu9 made glxinfo not crash when nvidia-glx-185 is installed. Upgrading the two packages to 2.10.1-0ubuntu11 made the crash reappear, and removing nvidia-glx-185 to disappear again. So, this is some kind of mismatch between the new libc packages and Nvidia's drivers.

[3vi1 (launchpad-net-eternaldusk)]

Pauli's observations match with my own: I noticed the problem right after upgrading the libc6 packages. taking them back to the ubuntu9 versions made the issue disappear.

[Gary Butters (gbutters)]

downgrading libc6 and libc6-i686 to 2.10.1-0ubuntu9 also fixed the problem for me.

[Nick B. (futurepilot)]

This also affects nvidia-glx-96. glxinfo crashes, compiz can't be started, X gets stuck in a continuous crashing loop on bootup.

[Matthew Brooks (mjbrooks)]

If you're stuck with a black screen on boot because of this and can't seem to CTRL_ALT+F1 press ALT+PRINTSCREEN+R to release the keyboard from the Xserver. You can then hit CTRL+ALT+F1 to get a TTY

If you just want to get around the issue you can use the NV driver by editing xorg.conf

sudo nano /etc/X11/xorg.conf

Then edit the part that reads:

Section "Device"
Driver "nvidia"

to:

Section "Device"
Driver "nv"

Save the file and then reboot (or in Kubuntu /etc/init.d/kdm restart or in Ubuntu /etc/init.d/gdm restart). That should get your desktop up and running, minus any extra video effects requiring compositing

At least some people reported that that works, however, although I could see the KDM login screen, X would crash when I tried getting in, so I had to remove nvidia altogether. Again at the terminal (and assuming you are using v185):

sudo apt-get purge nvidia-glx-185 nvidia-185-kernel-source

and then after a /etc/init.d/kdm restart I was good to go

For those interested in downgrading the troublesome packages temporarily so they can keep using compositing, but aren't sure how:

If you've been on Karmic for a bit, you probably already have the packages needed in /var/cache/apt/archives/

sudo dpkg -i --force-downgrade /var/cache/apt/archives/libc6_2.10.1-0ubuntu9_i386.deb
sudo dpkg -i --force-downgrade /var/cache/apt/archives/libc6-i686_2.10.1-0ubuntu9_i386.deb

If not you can grab them from http://archive.ubuntulinux.org/ubuntu/pool/main/e/eglibc/

I also had the dev package installed, so I needed to downgrade that due to dependencies:

sudo dpkg -i --force-downgrade /var/cache/apt/archives/libc6-dev_2.10.1-0ubuntu9_i386.deb

Keep in mind, that unless you pin these they will be updated back to the broken ones if you apply an update (and it will be reported as there being an update available as soon as you do this), so either pin them or wait for this bug to be reported as resolved before doing another update.

Lastly, I heard a couple of people say that manually installing the NVidia driver from NVidia's website fixed their troubles, however I can't confirm this personally and it would really only be a last resort solution for an end user anyways. So since the point of Alpha 5 is to work out the bugs, going this route means you aren't at all interested in helping to fix the issue or identify others down the road and really shouldn't be on Karmic in the first place... let alone complaining about things getting broken in an "ALPHA DEVELOPMENT" release.

[Alberto Milone (albertomilone)]

Please don't install the NVidia driver from NVidia's website. Downgrading libc6 is sufficient.

[Matthew Brooks (mjbrooks)]

Sorry Alberto, I hope I wasn't giving the impression that I was recommending the driver from NVidia's website. I was just putting the information out there since some people were already mentioning it. In fact, I was trying to frame it as best I could as a "you probably don't want to do this, but...."

[Daemonk (1-daemonk-gmail-com)]

Hi, I am having this. My problem with the nv driver is that I cannot get my dual screens to work properly. Only the restricted driver works as it should. Thanks for the instructions on the downgrading.

[Lane Lester (llester)]

The site http://archive.ubuntulinux.org/ubuntu/pool/main/e/eglibc/ only has ubuntu11 files, not ubuntu9. I went ahead and tried them after switching back to "nv" in xorg.conf. But I got the black screen again.

[Loïc Martin (loic-martin3)]

Just for those that need the proprietary drivers back urgently ;)

This also affects nvidia Beta (190.32, 190.18) and Old drivers (96.x 170.x)

This is the reason why nVidia drivers need to be open source.

[bazookatooth (wesley-hall)]

No, this is the reason that Synaptic needs to have a rollback feature.

[Lane Lester (llester)]

Thanks for all the tips and links, guys. I downgraded the two non-dev packages and now the 185 driver is doing its thing.

Synaptic sure wants to put those newer libs back; is there a way to block that?

[3vi1 (launchpad-net-eternaldusk)]

There definitely needs to be a rollback feature, but not one specific to synaptic (it's not even installed by default in Kubuntu, no?).

It should probably be an option from the recovery menu: "roll back packages since [time|last-successful-boot]".

This probably won't happen much to non-alpha/beta ("average") users, but would be a nice feature just in case someone hoses their production system with a 3rd party package.

Oh well, hopefully the Ubuntu gurus are working out the problems and we either get new libc6 or nvidia-glx-* packages soon. Until then I'm just pinning the libc6 packages to ubuntu9.

[Lane Lester (llester)]

I guess my question, "...is there a way to block that?" should have been, "How do I pin the older libraries?" I did a search and found this:
Edit /etc/apt/preferences with something like this:
   1. Package: ruby
   2. Pin: release a=hardy
   3. Pin-Priority: 900

Is that what needs to be done? If so, is this what goes in the lines?
   1. Package: eglibc
   2. Pin: release a=jaunty
   3. Pin-Priority: 900
Or something else?

[Loïc Martin (loic-martin3)]

System>Administration>Synaptic Package Manager

Look for the package you pant lo lock, select it, then Package>Lock Version

[Lane Lester (llester)]

Thanks, that's much easier!

Synaptic said I had broken packages and wanted to remove libc6-dev (11), nvidia-185-kernel-source, and nvidia-glx-185. Since I'm using the 185 driver, I think I'll leave things alone.

[3vi1 (launchpad-net-eternaldusk)]

Locking them in Synaptic will only effect upgrades done through Synaptic. Pinning the versions will prevent any of the utilities from seeing the updates.

After you backlevel the following packages to the 9 release, create a new file called '/etc/apt/preferences' which contains everything between the following dotted lines:
-------------------------------------------------------

Package: libc6
Pin: release
Pin-Priority: 999

Package: libc6-dev
Pin: release
Pin-Priority: 999

Package: libc6-dev-i386
Pin: release
Pin-Priority: 999

Package: libc6-i386
Pin: release
Pin-Priority: 999

-----------------------------------------

When a fix for the issue is released, simply delete or rename /etc/apt/preferences.

[Vincent DAVY (vincentdavy)]

I confirm that downgrading to to the previous version of libc6 and libc6-i686 worked fine for me.
hope the fix will come quickly

[Hans van den Bogert (hbogert)]

I've been pulling hairs the whole day of frustation. Even installed the vanilla nvidia driver from their website. Well that didn't work.
Thank god I found this bugreport.
many kudo's for well explained downgrade/workaround

[Matthias Klose (doko)]

I have put some test packages at

  deb http://people.canonical.com/~doko/tmp/eglibc/test1 ./
  deb http://people.canonical.com/~doko/tmp/eglibc/test2 ./
  deb http://people.canonical.com/~doko/tmp/eglibc/test3 ./

'tseliot' on irc did confirm this behaviour with the test1 packages as well, but I didn't get any feedback on the test2 and test3 packages. Can't test this myself, no nvidia hardware available.

[Niklas M (niklas-mattisson)]

Downgrading libc6 solved my problems with getting into X also.

[Neil Woolford (neil-neilwoolford)]

Me too with the older nvidia 96 drivers.

Thanks very much to mjbrooks for the downgrade libc6xxx tip which has restored function for me.

[John Yates (andyfranyates)]

I tried the "test2" packages from #28 above and they work like a charm with the
"NVIDIA-Linux-x86-173.14.20-pkg1.run" from Nvidia site.
Harware here is Nvidia FX-5900.
I am running Karmic with kernel 2.6.31-10-generic.

test2 and test3 have the same problem. X fails to start and gets
caught in a crashing loop.

test3 packages are not working for me, same problem.

[Loïc Martin (loic-martin3)]

test2 packages not working with Ubuntu's 185 nvidia drivers.

I also noticed that after installing the test2 packages and before rebooting, glxinfo and glxgears both segfault.

[Neil Woolford (neil-neilwoolford)]

Sorry to say that the test3 packages didn't work here either, sorry...

[Fahim Abdun-Nur (fahim-a)]

Thanks mjbrooks for the downgrade libc6 instructions...

[Reuben (reub2000)]

This also seems to affect KDE/QT programs. KDE would not start when using the nv driver, and trying launch amarok from fluxbox resulted in a segfault. After downgrading glibc to ubuntu9, all of the issues with QT apps have gone away.

[Pauli Virtanen (pauli-virtanen)]

@Matthias Klose:

I think it is well possible to test this without any Nvidia hardware: you probably can just do

    $ dpkg-deb -x nvidia-glx-185_185.18.36-0ubuntu2_i386.deb xxx
    $ LD_LIBRARY_PATH=$PWD/xxx/usr/lib glxinfo

and observe the crash -- it occurs on shared library load, very likely before Nvidia's GL library even tries to access the HW. Consider also:

    $ cat test.c
    int main() { return 0; }
    $ gcc -o test test.c -lGL
    $ LD_LIBRARY_PATH=$PWD/xxx/usr/lib ./test
    Segmentation fault (core dumped)

It crashes before reaching main(). Also, something strange is going on here:

    $ LD_DEBUG=all LD_LIBRARY_PATH=$PWD/xxx/usr/lib ./test
    [clip]
    6922: symbol=pthread_key_create; lookup in file=/usr/lib/libXdmcp.so.6 [0]
    6922: ./test: error: symbol lookup error: undefined symbol: pthread_key_create (fatal)
    Segmentation fault (core dumped)

I don't know (as of now) how to debug the .init section code of a shared library, so I'll have to stop here.

[Steve Langasek (vorlon)]

The latest eglibc upload is believed to fix this bug. Changelog:

eglibc (2.10.1-0ubuntu12) karmic; urgency=low

  [ Steve Langasek ]
  * Restore missing depends/conflicts/replaces handling for findutils and
    belocs-locales-bin, lost in the latest merge.
  * Move ldconfig trigger handling to libc-bin postinst, since that's where
    ldconfig and the trigger are actually located.
  * Drop debian/local/etc_init.d from the source, which is no longer shipped
    in the package having been dropped in Debian
  * debian/rules.d/debhelper.mk: revert breakage from Debian experimental;
    pulling in file substitutions from script.in has to happen before
    substituting other tokens, since script.in/nohwcap.sh contains other
    tokens that have to be replaced. LP: #427288.

  [ Matthias Klose ]
  * Don't apply hppa patches, don't apply
    any/local-linuxthreads-kill_other.diff.

Please reopen if you still see problems after upgrading.

[Dan Andreșan (danyer)]

Updated, rebooted, fix confirmed!

Thanks Steve, Matthias and all who commented/subscribed to this bug.

thanks all

[Eric Casteleijn (thisfred)]

Upgraded my laptop just now (after downgrading the libc6 packages yesterday which worked) and xorg no longer crashes on startup, but after logging in, I get an empty desktop. Not sure if that's related to this bug or if I should open a new one.

[Brian Curtis (bcurtiswx)]

Eric,

What do you mean by empty desktop? Is there icons but no taskbars? no icons or taskbars? no desktop image?

I had a blank taskbar, but all I needed to do was click where I knew something was and it reappeared.

Try that, if not then its probably a different bug and should be reported separately

[Christian Mangold (neversfelde)]

I can confirm that latest packages fixed this problem.

[Timothy Pearson (kb9vqf)]

Confirmed fixed here!

[Eric Casteleijn (thisfred)]

Brian:

No icons, no taskbars, desktop background is there. When I click somewhere the taskbars seem to appear very briefly and then disappear again, so I guess something's crashing. Will investigate more, and file a new bug, if it's not already there.

[SRElysian (srelysian)]

Confirmed fixed here on my end as well, prior to that I had the package

[KeenEars (fl-blade)]

Thanks, fix helped me too with nvidia-glx-185. Just installed last updates.

[Vernz (vernon-rowe)]

Confirmed also. Problem has been fixed.

Thanks for the good work.

[Sven (brettschneider-sven)]

The fix is working also for me!

Thanks, it's working perfect again!

[srikumar (srikumar108)]

I just installed Karmic beta and I have the same problem. nvidia v. 185.18 is unusable, flickering screen, random garbage and finally lockup. Please reopen the bug report

[Pauli Virtanen (pauli-virtanen)]

@srikumar:

That doesn't sound like it's the same bug. For instance, I see this bug any more.

There can be more than one cause for why X would crash on startup, and this one has most likely been fixed.
Please file a separate bug report, thanks!

[Johannes (johannes-paradise)]

Brave as I am, after a release upgrade from 9.04 to 9.10 am experiencing the exact same as post #53 even after downgrade of libc6 as suggested earlier in this thread. Using 'Trident Microsystems XGI Volari XP5 (rev 02) on pci 01:00.0

It IS an x-driver issue. I can say that much. Other unusual things happened like some messed up log files in /var/log and the .viminfo of the root account. Also the Xorg.0.log contained total garbage on occasion.

All happening on an ECS 532 notebook with transmeta TM8600. Everything, including wireless, worked fine under Kubuntu 9.04(jaunty). Any hints are much appreciated. Any way to revert to 9.04 short of a re-install?

What's a good way to go about to trace that bugger?

Cheers

Johannes

[Reuben (reub2000)]

Sounds like you've stumbled onto a new issue. The original issue was in the C libraries, and was fixed.

Also take a look at Xorg.0.log.old is Xorg.0.log is garbage.

[Pablo Marchant (pamarca)]

@Johannes

This bug is closed, and your bug is different, so you don't have to comment in this one. You should open a new bug (or search if anyone else has the same issue and posted another bug to avoid duplicates), and keep all the discussion there. Only if you think this bug isn't really solved, or there's a regression that makes this bug reappear you should add comments here.

[Jack Deslippe (jdeslip)]

I am pretty sure this bug (or something related) has been reborn in recent days. I have a up to date Karmic computer and after "installing" the 185 driver in "hardware drivers" the system boots to a black screen. I.e. X doesn't start. This both with a 8400 card and 9400 card.

[Pablo Marchant (pamarca)]

@Jack, there are millions of reasons why X might not start. The one that produced the bug in this case related to an update of libc6 that caused a problem, that was fixed in a later version. This bug affected all hardware that used the nvidia driver version 185. As I am using this driver in an up to date karmic, I am mostly sure this bug hasn't regressed. You should look if your bug has been reported by someone else, and if it hasn't, then report one yourself. Remember you should follow this guidelines in doing so:

https://wiki.ubuntu.com/X/Reporting

[Carey Underwood (cwillu)]

Updated today, and X broke. I then reverted to the libc6 packages linked above, and things started working again.

[Steve Langasek (vorlon)]

This bug is resolved. File a new bug for problems you're seeing, this bug is unrelated.
