X/GDM crash (segfault) by firefox using nVidia 169.12 drivers

[Dr Paul Brewer]

0)SUMMARY:
In firefox, scrolling the current window by using the mouse wheel triggered seg faults in Xorg and compiz.
This bug seemed to be specific to viewing certain content. For example, I am having no problem with scrolling in the ubuntu lanuchpad site.
The problem occurred when looking at (work) email over the web at a webmail/MSoutlook-driven site.

The bug kills the current X session, causing the screen to go black. X then resets, and produces the login screen.
The bug also generated the following log entries in /var/log/messages

The bug persists after system poweroff/reset.

Each of these was caused by trying to scroll an email message viewed on a webmail web site using firefox.

3) What I expected to happen:
I expected rolling the mouse scroll wheel to scroll the current window up or down.

4) What happened instead:
X crashes, screen goes black, X resets. See summary (0) at top for log entries.
This bug does reproduce, but only in certain specific situations. Often, the wheel mouse is fine.

[Cinar Sahin (csahin)]

Exact same setup and exactly the same problem:

scrolling in firefox when viewing certain content crashes compiz/gdm causing an X restart. It doesn't happen often. Here's an example site that causes a crash:

http://developer.pidgin.im/ticket/4986

[Cinar Sahin (csahin)]

the crash also occurs when you use the scroll bar instead of the mouse wheel.

[Dr Paul Brewer (drpaulbrewer)]

I confirm Cinar's report that with ubuntu Hardy, you can click here to crash X

http://developer.pidgin.im/ticket/4986

For some reason, this web page upsets something....firefox...compiz...gdm...xorg...something...

Why has the title been edited to say this say this bug is not in Ubuntu?
The ubuntu product includes this collection of software and default configuration settings... people expect to be able to click on web pages
without causing a desktop crash and, for a desktop release, it should work reliably to view web pages without further tweaking.... so I'd call it a bug.

Cinar said you needed to scroll the page. I found clicking on the site above to be sufficient to crash X.

[Cinar Sahin (csahin)]

i might have to scroll due to my screen resolution (1280x1024). I also confirmed the crash on my laptop running Hardy but has Nvidia NVS 140M. Both are using the 169.12* drivers.

I also found the following message in the daemon.log:

May 1 00:48:29 xxxx-hostname gdm[7444]: WARNING: gdm_slave_xioerror_handler: Fatal X error - Restarting :0

I'm not sure why the title says the bug is not in ubuntu, I don't know how to change it either...

[John Vivirito (gnomefreak)]

Everyone needs to use apport to file the crashes and file your own bug reports we can only handle one crash per bug report, If apport finds its a dup it will mark it as such you can either reproduce the crash and use apport or you can go into /var/crash and double click the file for you latest crash.
Closing this bug report due to lack of Imformation needed to proceed.

[John Vivirito (gnomefreak)]

Im gonna let the gdm and compiz guys close thiers if they want but i would need a crash report for firefox crash and if compiz and gdm are crashing i have a feeling its not firefox but would need crash report to tell.

[Dr Paul Brewer (drpaulbrewer)]

In previous message, John Vivirito suggests crash report is invalid without /var/crash files or automatic apport report, and sets bug to Invalid.

I agree with John that automatic mechanisms for reporting bugs are preferable, since users can never really know what a developer needs to locate the problem.
However, apport does not deploy to do anything in this situation.

There were no /var/crash files generated.

apport 0.108 is part of Hardy and is installed.

As documented, apport is a gui application that runs under X and asks, when an application abort, if the user if they want to file an automatic crash reports.
If X is dead, apport, which would ordinarily pop up a dialog to ask the user what to do (send report, or restart program) is probably killed with all the user processes that rely on the X server
connection to continue. If the X server is dead, there is no way for apport to pop up its dialog boxes.

So far, the only application I have used that dies when scrolling is firefox. So this doesnt seem to be isolated to Xorg or compiz,
though they are implicated in the /var/log/messages log.

I would think the report of this bug from two different sources would elevate it to "Confirmed", but perhaps in the
rush to clear reports this aspect of the problem went unnoticed.

Clearing the report as Invalid seems a bit premature, I have put it back to "new". I would be willing to cooperate further,
if it can help. A link has been provided that crashes X reliably for me when firefox is used to view it on Ubuntu 8. Does this link crash your X
as well, John?

[John Vivirito (gnomefreak)]

No i am unable to reproduce this bug in firefox-3b5 nor firefox-2.0. most likely if X crashed it caused crash for firefox. Now if you ca get a backtrace of the issue than we will leave this open if it shows anything but without a verbose backtrace this is gonna be just about impossible to do anything with. I seem to feel it was not a crash if apport didnt send log to /var/crash. If you crash X anything you had running is going to report a crash when you log back in they are caused by the original crash and firefox nor gdm will cause X to crash it would be the other way around. Marking as incomplete until we get the back traces needed.
To backtrace please follow instructions at https://wiki.ubuntu.com/MozillaTeam/Bugs

Please dont set the status back to new alway set it back to incomplete since i have asked for information.

[John Vivirito (gnomefreak)]

oh and X crash will cause all of the above crashes at same time

[Sebastien Bacher (seb128)]

note that apport is not enable on stable so you need to edit /etc/defaults/apport to get it running

[John Vivirito (gnomefreak)]

Sebastien i forgot about that,
Paul and Cinar please turn off compiz and reboot without it starting whn you reboot and than go to the site listed above and see if you can crash it. i have tried 10+ times and since i dont have compiz enabled im not seeing a crash at all. It may not be compiz fault but here without it i dont crash

[John Vivirito (gnomefreak)]

Ok here is what i tested.
Went to above site with no compiz scrolled with mouse up and down, with arrow up and down, sliding the bar up and down = no crash
compiz normal enabled same tests as above = no crash
compiz extras enabled same tests as above = no crash
everything crashed because X crashed for some reason
Please try to obtain a backtrace when you can reproduce this bug
my screen res. is 1600x1400 i have a nvidia fx 5200 the common issue im seeing is both your X are crashing with gdm errors inneither log that you have given does it say anything about firefox. Leaving open until someone can reproduce this i will have a few of the Mozilla team members test this if they can.

[John Vivirito (gnomefreak)]

What themes are you using when you reproduce this.

[Saša Bodiroža (jazzva)]

Hello,

Tested with compiz enabled, and I wasn't able to reproduce this crash. Though, I am using an ATI graphics card.

[Dr Paul Brewer (drpaulbrewer)]

Summary: crash exists after removing compiz, viewing content at http://developer.pidgin.im/ticket/4986
with firefox still causes firefox->Xorg crash, black screen, X reset.

Even after activation, apport will not provide crash dump. At best it intermittently leaves
behind a .lock file in /var/crash

Well, I suppose since compiz was removed, it is not compiz's fault...also still can't get apport to do anything

$ sudo apt-get remove compiz

is it gone...? Yes.

$ sudo apt-cache policy compiz
compiz:
  Installed: (none)
  Candidate: 1:0.7.4-0ubuntu6
  Version table:
     1:0.7.4-0ubuntu6 0

Now to try to get apport going

emacs /etc/default/apport
# set this to 0 to disable apport, or to 1 to enable it
enabled=1
# set maximum core dump file size (default: 209715200 bytes == 200 MB)
maxsize=209715200

*REBOOT*
log back in
bring up firefox
visit http://developer.pidgin.im/ticket/4986
X crashes...black screen...login again...no apport response
only a .lock file in /var/crash

The following apport behavior seems screwy... according to the source in
/etc/init.d/apport it is supposed to recognize that it has been started already
when started a 2nd time and give a different exit code.

sudo /etc/init.d/apport startsudo /etc/init.d/apport start
 * Starting automatic crash report generation: apport [ OK ]
pjb@pjb-linux-desktop:~$ sudo /etc/init.d/apport start
 * Starting automatic crash report generation: apport [ OK ]
pjb@pjb-linux-desktop:~$ sudo /etc/init.d/apport start
 * Starting automatic crash report generation: apport [ OK ]
pjb@pjb-linux-desktop:~$ sudo /etc/init.d/apport start
 * Starting automatic crash report generation: apport [ OK ]

Is there some other setting I could be missing to get apport to work correctly?

Anyway, I will try to go through the mozilla backtrace procedure later when I can have some time.

Thanks in advance for reading all of this.

X still crashes with compiz completely removed; so problem does not originate from compiz.

I tried disabling compiz and enabling compiz. Crash still occurred with no report. I then tried on a third system with an nvidia graphics card using the 96.* drivers, firefox did not crash in that setup.

Then I tried uninstalling the nVidia drivers and the crash stopped happening (on both systems that were crashing).

The crash must due to the Nvidia drivers, but I still can't explain why firefox is the only application that is triggering the crash.

I am marking the gdm bug as invalid. Please advise on how we can get backtraces or crash reports through apport. I do get a /var/crash/.lock file but nothing else.

please get a backtrace by following instructions at https://wiki.ubuntu.com/MozillaTeam/Bugs#preview
I am still unable to reproduce this bug. Please list all addons, extensions, plugins, themes you have installed so we can further help with this bug. No matter how many times i open the link and scroll i am unable to get a crash.

[John Vivirito (gnomefreak)]

Please leave these open until we can confirm its firefox causing the crash and we cant do that without a backtrace or crash report.

[John Vivirito (gnomefreak)]

I just tried on my other Hardy set up and still cant reproduce it with the link that is there nor in my gmail accounts (7)

[John Vivirito (gnomefreak)]

Ok ive pinpointed where its coming from ive had about 10 people test this on all different nvidia/ati cards and the one thing that is common to all of the crashes is the 8800 nvidia card using the nvidia-glx-new drivers. There will be more info soon but we will still need those backtraces to find out why the 8800 isnt playing nice with our drivers, it still maybe a nvidia bug since we cant alter the drivers.

[John Vivirito (gnomefreak)]

8600 series also crashes on that site.

Apparently there is a fix on the way for this. I am confirming the bug since the fix is already in the way for linux-restricted-modules package. The link for the package overview and fix:
