nvidia drivers broken by the recent libc update on i386 arch

[Jeroen T. Vermeulen]

Automatically reported crash while logging in after boot, running Precise beta with continuous updates.

Login was also very slow, and Unity doesn't seem to have appeared: there is no launcher panel or menu bar, non-maximized windows have their menus inside the window, and maximized windows have their menu bar at the top but without Ubuntu logo on the left. There are no indicators, clock, and so on.

I tried this with both “Ubuntu” and “Ubuntu 2D” logins; same result. I think I'm normally on Unity 2D (from PPA) but my session option in the login screen does show “Ubuntu” by default.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Carlo Piana (carlo-piana)]

I resolved all issues by removing the proprietary accelerated driver (Nvidia). Now everything is blazingly fast.

[Jeroen T. Vermeulen (jtv)]

In my case, I don't think I have that driver installed in the first place. I tried it once but uninstalled it in a hurry. The Hardware Drivers UI doesn't show it installed either. But confusingly, I do seem to have nvidia-common, nvidia-settings, and nvidia-current installed.

[Fabien Tassin (fta)]

Happens here too, when running the nvidia-current driver from precise. It also makes gnome-shell crash on startup.

this is caused by the eglibc update (2.13-24ubuntu4 -> 2.15~pre6-0ubuntu10). I reverted it, it's fine now.
(but reverting this libc6 is not easy as more packages are rebuild for it, leading to failing GLIBC_2.15 version checks everywhere)

[Sebastien Bacher (seb128)]

Thanks Fabian, that's very useful informations

[dino99 (9d9)]

I have precise i386 + nvidia 290.10 + 8500gt and logged as gnome-classic (compiz/unity completly purged) and does not have special issue as described here.

[Jeroen T. Vermeulen (jtv)]

I've had one or two libc upgrades after reporting this earlier today, but the problem persists.

[Jeroen T. Vermeulen (jtv)]

Not sure this needs repeating, but note that I'm having this problem without nvidia-graphics-driver installed.

[Oleksii Zhukov (axe-z)]

@dino99 this issue affects exactly unity panel :)

[Rachel Greenham (rachel-strangenoises)]

have nvidia, did upgrade as normal this morning, which I noticed *did* include libc6 and kernel. Been using it since, with no problems except handbrake's picture setting window won't open when run locally, which is probably unrelated.

rachel@twilight:~$ uname -a

Version: 290.10-0ubuntu2
rachel@twilight:~$ aptitude show libc6 | grep ^Version

Though I think I might have seen something like it in the past, but probably unrelated and just looks similar.

[Robert Hooker (sarvatt)]

I may be missing something here, but all of the affected systems I've looked at so far are i386, amd64 seems to be unaffected

[Bryce Harrington (bryce)]

Jeroen, to clarify, you may not think you are using nvidia, but the bug report captured a crash that appears to happen in nvidia's GL code:

 Thread 1 (LWP 2423):
 #0 0xb761f216 in ?? () from /usr/lib/nvidia-current/libGL.so.1

Your X logs just show -vesa loaded, which doesn't tell us much.

I think to work around the issue, you should do an apt-get purge of the nvidia files (you can leave nvidia-common installed, it's harmless.)

We anticipate having an updated -nvidia ready later today that will support this new libc.

[Fabien Tassin (fta)]

indeed, I see this on i386 too.
I tried to get a proper trace, but a/ the apport crash file always gives a 1 line unresolvable trace and 2/ it doesn't crash in gdb.

[Robert Hooker (sarvatt)]

Bryce: The newer nvidia driver discussed in IRC was a red herring and does not fix this issue. the reason we couldn't reproduce it on the newer nvidia driver was because it was on amd64, this is an eglibc bug limited to the i386 arch

[Bryce Harrington (bryce)]

@Robert, gotcha. bummer

[bobhuber (bobhuber-tampabay)]

Nope - Nvidia GT430 - AMD AthonII X4 - 64/bit

[Colin Watson (cjwatson)]

@bobhuber: Are you definitely running a 64-bit OS on that, though? See what 'dpkg --print-architecture' says.

@Fabien: I don't suppose valgrind produces anything useful?

[Andreas Hasenack (ahasenack)]

output of nvidia-bug-report.sh attached

[Fabien Tassin (fta)]

@colin: it doesn't crash in valgrind either, but shows 1 unfreed block in libGL.

[Rachel Greenham (rachel-strangenoises)]

I definitely am:

rachel@twilight:~$ dpkg --print-architecture
amd64

Also, started to suspect something when I didn't even have any such package eglibc; but wasn't sure what that was about, hence trying to be sensible and reporting my libc6 version instead.

[Colin Watson (cjwatson)]

@Rachel: eglibc is the source package that builds several binary packages including libc6.

It looks like the linked Fedora bug may have the answer here: http://sourceware.org/git/?p=glibc.git;a=commitdiff;h=0c95ab64

[Chris (fabricator4)]

Confirmed here - I just updated.
No Launcher, No top panel. Nvidia Settings crashed, Apport crashed. I think some of the crashes crashed.

Wheee! that was fun.

[Bryce Harrington (bryce)]

These packages appear to fix it:
  http://people.canonical.com/~doko/tmp/eglibc-2.15/i386/

[Bryce Harrington (bryce)]

Verified on nvidia hardware, as well as an intel box (with nvidia-current installed).

[Launchpad Janitor (janitor)]

This bug was fixed in the package eglibc - 2.15-0ubuntu2

[Steve Langasek (vorlon)]

according to the comments on the eglibc patch from one of the upstream authors, this is a workaround for what's really a bug in the nvidia driver. I don't know if we want to keep the nvidia-graphics-drivers task open, but that's certainly not anything foundations can fix, so unassigning from us.

[Alberto Milone (albertomilone)]

I'm subscribing Nvidia to the bug report.

@Daniel: any ideas on the issue?

[Jeroen T. Vermeulen (jtv)]

Last night's updates seem to have solved the problem. That makes about 16 hours from first hitting the problem to a fixed system, all the way at the other end of the package pipeline. Thanks!

[dino99 (9d9)]

Only waiting for all the packages using libc6 to be rebuilt (and they are numerous) to take advantages of the fixes. (might fix some other sad effects here & there)

[Andreas Hasenack (ahasenack)]

Working fine here too.

[Anadon (joshua-r-marshall-1991)]

I've had plenty of issues with my video/driver. There's still one with unity corruption. I never had the performance hit, but that's because I've been using the most recent drivers off of nVidia's site.

[Colin Watson (cjwatson)]

@dino99: Nothing should need to be rebuilt for this.

[Mark Hannon (markhannon)]

Have upgraded to latest glibc as mentioned above but still crash on an 11.10 32 bit system upgraded to precise. (laptop running 64 bit with same versions not affected).

[Daniel Dadap (ddadap)]

The next 295 driver version will contain a fix for this issue.

[Ivo Anjo (knuckles)]

I'm sorry if this is unrelated, but I used synaptic to upgrade my system today, and after reboot the nvidia binary driver was gone and I was running nouveau. Is this expected? I didn't see anything about nvidia-current being removed.
(I'm running a 64-bit system.)

[Launchpad Janitor (janitor)]

This bug was fixed in the package nvidia-graphics-drivers - 295.33-0ubuntu1

---------------
nvidia-graphics-drivers (295.33-0ubuntu1) precise; urgency=low

  * New upstream release:
    - Added support for the following GPUs:
      o GeForce GTX 680
      o GeForce GT 630M
      o GeForce GT 620
    - Fixed a VDPAU bug where decoding some H.264 streams
      would cause hardware errors on lower-end products,
      resulting in corruption and poor performance.
    - Fixed a bug that caused DisplayPort audio to stop
      working after monitors are hotplugged on GeForce GT
      520.
    - Improved compatibility with recent Linux kernels.
    - Fixed a behavior change that prevented
      ConnectedMonitor from being usable with DisplayPort
      connectors.
    - Marked the GVO Clone mode NV-CONTROL attributes:
      NV_CTRL_GVO_DISPLAY_X_SCREEN
      NV_CTRL_GVO_X_SCREEN_PAN_X
      NV_CTRL_GVO_X_SCREEN_PAN_Y
      as deprecated. They will be removed in a future
      release. To display an X screen over GVO, it is
      recommended to use GVO with MetaModes, instead.
    - Fixed a bug that caused DisplayPort devices to not
      be listed in Xorg.*.log.
    - Added support for 3D Vision ready displays that
      have a NVIDIA 3D Vision infrared emitter built
      inside the panel itself.
    - Fixed a bug that caused OpenGL applications to
      crash with some libc versions, such as eglibc 2.15
      (LP: #929384).
    - Fixed a bug that caused HDMI audio to stop working
      on AppleTV devices when an X server was started.
  * debian/nvidia-$flavour.postrm{.in}:
    - Make sure to remove the blacklist for hybrid
      graphics and to rebuild the initramfs (LP: #958848).
