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

[Nicolas DERIVE (kalon33)]

Occurs in unity session too.

[Giovanni Mellini (merlos)]

confirmed in unity too

[xe2xpk (skorlowsky)]

This happens in Unity, nothing to do with gnome.

[Noel Arzola (noel.arzola)]

amd64 too after recent updates and reboot unity all weird wallpaper offcenter and got this crash, it reports it as gnome3 when you send it up so idk

[runnermule (reg-launchpad)]

Gateway Atom netbook. Default Unity. Previously upgraded from 11.04. Unknown display driver (not 3rd party). Oneric updates by Update Manager. Previous daily updates have been uneventful. After required reboot, two attempts to log in hung with either an arrow or an X cursor on a black screen. Had to hold the power button down to power off; system froze. After two reboots I could log in, but the wallpaper shrank to fill only part of the screen. Then a closing application (Gjot?, just installed) started looking smeared like a fuzzy, duplicated image of itself. Followed by failure pop-up windows and requests to report.

[Fayer Michael (fayer012)]

After a partial upgrade (I think about 120+ software updated), rebooting and login, this error occurred. After this upgrade, I also cannot see any icons (eg, time) at top-right corner, don't know if it's a new setting or bug.

My system:

$ lsb_release -rd
Description: Ubuntu oneiric (development branch)
Release: 11.10

[Fayer Michael (fayer012)]

After another partial upgrade (~76 softwares updated), top-right icons came back! And after reboot, this error didn't appear!

[Barry Drake (b-drake)]

This error occurred after opening I/O->Displays just as the 'displays' window opened.

[Devon Private (dawiz-99)]

Just after opening Banshee. Audacious please...

[Brad Needham (fishrcynic)]

error appeared on desktop nothing else seems out of place

Comment from duplicate bug #865358: Ooh, wow. It's failing to connect to X. Could you please try the packages in https://edge.launchpad.net/~raof/+archive/aubergine which should (a) not crash in this circumstance, and (b) print a little debugging information to .xsession-errors.

[Doug McMahon (mc3man)]

With the raof packages I get the same symptoms that this crash produced, again it's on random startups
The crash is now _sbin_plymouthhd.0

[Fayer Michael (fayer012)]

This is the 2nd time no icons (e.g., time and date) shown on the top panel. I didn't do anything special when the error occurred, I think. Ubuntu may want to give a stronger warning when users want to upgrade to such an very unstable beta release (I have almost reported 10+ bugs after upgrading).

[Doug McMahon (mc3man)]

Ignore about the sbin crash, never seen before, hasn't occurred again
For me this crash is related to this - Bug 863054 & to note - this crash & that bug never occur if gdm is used instead of lightdm

[Guruprasad (lgp171188)]

I have reported more than 50 bugs most of which totally make the desktop unusable. :-(

[miked (miked11)]

Ubuntu ix386.iso install Beta 2 of 11.10 Oneiric Ocelot on Dell Laptop Inspiron 6000.

[Chris Halse Rogers (raof)]

This particular crash is harmless, although it's a symptom of something else going wrong. The code which invokes check_gl_texture_size fully expects it to crash sometimes, and handles it. Once apport is turned off the only way you'll notice this crash is a SIGSEGV message in dmesg.

Of course, until the underlying problem which triggers this (which would be associated with bug 863054) is fixed, you'll still have the other symptoms caused by that.

[xe2xpk (skorlowsky)]

it did it once again, just starting Unity

I am using Ubuntu 11.10 development branch with Unity

This occurred after a reboot following the latest update: Oct 5, 2011 @ ~10:15 AM EDT.
I did have to reboot twice. The first reboot left my touch pad / mouse and keyboard unresponsive and I had to use my power button to shut down and restart.

It followed a crash of the Ubuntu One Indicator which said it could not be reported because it was not a Genuine Ubuntu package.
The Ubuntu One Indicator did start.

[Guruprasad (guruprasad-iyer20)]

Every time wen i boot my laptop( Dell Inspiron 14r N4010). Unity seems to be the problem.

[Colin Mills (cm006a5077)]

Occurs intermittently after update today (5/10/2011).

 I am runining Ubuntu 11.10, 64 bit and running in 3D mode.

[dava4444 (dava4444)]

Unity 3D, the icon in the top panel shows an empty wifi symbol, and my name indicator is missing. i dont have wifi on this desktop, and praise the Lord, the ethernet is still working. I checked the network settings and no ethernet is listed, but im online just now. i did the update today then logged out to check i/we have the cool new log in screen (WOW amazing login) and we i came back in.... this crash. this is on my HP Tuxbox, my lappy has a diffrent login.. the Gnome3 i think which i don't like, this one is muuuuch better :)

any chance of Canonical having a feedback form built into Betas in future? for opinions on looks? i just wanna give a lot of encouragement and Kudos to the Devs :D and of course design suggestions/ideas for free lol :D

[Doug McMahon (mc3man)]

@dava4444 (dava4444) -
what you're seeing is this - bug 863054

[skipper (attila-egri-nagy)]

Fresh update, clean reboot, starting Firefox, clicking on a link and I got this crash message. For the next click I could load the page though. :)

[amano (jyaku)]

Affects unity3D as well.

[peter swain (swine)]

seems to be resolved by yesterday's updates (at least for me)

[GonzO (gonzo)]

...me too. It's been several days since I've seen this on either test machine (desktop and notebook).

[Martin Pitt (pitti)]

Hello Pierre-Olivier, or anyone else affected,

Accepted gnome-desktop3 into oneiric-proposed, the package will build now and be available in a few hours. Please test and give feedback here. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!

[Guruprasad (lgp171188)]

Hi Martin,
This was a crash that happened randomly. How to test the fix?

[Pierre-Olivier Megret (sorrodje)]

Hi Martin .. no more crash since few days . I promise to report here if it happens again ;) .. thanks for all your work !

[Martin (mbattiti)]

This bug was fixed in the package gnome-desktop3 - 3.2.0-0ubuntu4.1

---------------
gnome-desktop3 (3.2.0-0ubuntu4.1) oneiric-proposed; urgency=low

  * debian/patches/02_refuse_to_break_GL_compositors.patch:
    - Add extra paranoid checks to fail gracefully in the case of errors in
      check_gl_texture_size. Eliminates (otherwise harmless) crashes.
      (LP: #862161, LP: #862998, LP: #861804, LP: #861548)
    - Wait for check_gl_texture_size no longer than 500msec. Ensures that
      this check will not block the desktop, as in (LP: #871188).
  * Remove debian-changes patch which accidentally reverted the change meant
    to be applied in 3.2.0-0ubuntu4.
