vnc log

Description of problem:

After doing a default F20 graphical install on a PPC64 machine, I started vncserver. When I connect using vncviewer I only see a black screen.

If I start opening and closing X clients, like firefox or gnome-terminal, from an ssh session (properly setting $DISPLAY), sometimes I can see the big "Oh No! Something has gone wrong" message just for a moment.

I'm attaching vnc and messages logs. Please let me know if you need further info to help debug this issue.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Install F20 on a PPC64 machine
2. Install tigervnc-server
3. vncserver :1
4. connect to VNC server using vncviewer

Actual results:

Expected results:

Proposing as PPC64 Alpha blocker, as a working graphical environment is part of the alpha criteria.

Sep 10 17:11:15 duff gnome-session[33991]: WARNING: Application 'gnome-shell.desktop' failed to register before timeout

Is an important message.  It means gnome-shell didn't register with gnome-session.  But I don't see any other error messages.

It's possible it's deadlocked on something?  Simply attaching with gdb is how I normally debug things.  Just:  gdb attach $(pidof gnome-shell); t a a bt

Comment 4 Gustavo Luiz Duarte 2013-09-18 16:30:52 UTC
KDE works fine on F20, so I'm moving this bug to gnome-shell, which seems more appropriate than the X server.

Comment 5 Phil Knirsch 2013-09-20 16:19:45 UTC
I've taken a look at it today and even looking through the changes in gnome-shell i can't see anything obvious.

Same for gdb outputs, there was nothing really obvious there either. :(

If anyone with more insight could take a peek at it that would be ace.

At least for RH folks i can give access to a freshly installed Fedora 20 with all shizzle necessary. Not sure if we've updated the OSU machine yet with Fedora 20 (i suspect not).

Thanks & regards, Phil

Comment 6 Ray Strode [halfline] 2013-09-25 15:55:21 UTC
so i got access to one of phil's machines and noticed this in the backtrace:

(gdb) thread 1

so the process is stalled in early initialization waiting to connect to pulseaudio.

I then ran  

mv /usr/lib64/libcanberra-0.30/libcanberra-pulse.so /usr/lib64/libcanberra-0.30/libcanberra-pulse.so.save

to prevent the shell from trying to connect to pulseaudio at start up and everything started working.  So this is some issue in pulseaudio. reassigning.  Could be some error path in pulseaudio is missing a pa_cond_signal call or something like that.

Comment 7 Phil Knirsch 2013-09-26 12:14:07 UTC
Thanks a lot Ray.

I've reassigned the bug to pulseaudio now. For access to the Fedora 20 ppc64 instance with the issue just let me know via private email or ping on IRC.

Thanks & regards, Phil

Comment 8 Arun Raghavan 2013-09-27 03:09:27 UTC
Can someone post verbose PA server logs as well?

Comment 9 Phil Knirsch 2013-09-27 11:27:24 UTC
Ok, so here's the full pulseaudio logging, following the debugging described in


The first part is the startup with

  pulseaudio -vvvvv                

The second part is the log after i do a


Any clues as to what causes the problem?

Comment 12 Phil Knirsch 2013-09-27 11:48:21 UTC
OK, i've also tried it with a fully downgraded pulseaudi stack to Fedora 19 and i'm getting the same error. So it seems the error comes from somewhere inbetween gnome-session and pulseaudio:

  Installing : pulseaudio-libs-3.0-10.fc19.ppc64

Aka, i went from pulseaudio-4.0-4 back to pulseaudio-3.0-10 which worked nicely in Fedora 19

Thanks & regards, Phil

Comment 13 Phil Knirsch 2013-09-27 12:51:38 UTC
And tried the same with libcanberra, same error:

  Updating   : libcanberra-0.30-4.fc20.ppc64

So backing down to an older libcanberra didn't help either.

Thanks & regards, Phil

Comment 14 Phil Knirsch 2013-09-27 12:57:03 UTC
And i've attached the pulseaudio log with the libcanberra-pulse.so moved away to make it work.

And unfortunately they are identical... O_O

So no clue whats happening and if it's actually a pulseaudio problem after all, it seems that pulseaudio gets the same messages and behaves exactly the same in both cases.

Thanks & regards, Phil

Comment 16 Phil Knirsch 2013-09-27 14:37:07 UTC
And another observation:

If you attach a gbd session to the hanging running gnome-shell and then CONTinue the process, it suddenly works...

Love it when things start to work as soon as you run them in a debugger. :(

Thanks & regards, Phil

Comment 17 Phil Knirsch 2013-09-27 14:38:40 UTC
Ah, but only if pulseaudio isn't running as a process.

As soon as i have pulseaudio running again it hangs again.

Thanks & regards, Phil

#include <stdio.h>
#include <stdlib.h>

        pa_threaded_mainloop *ml = data;

        unsigned int s = pa_context_get_state(c);
        printf("state: %u\n", s);

This code prints OK on ppc64 with glibc 2.17, but hangs with glibc 2.18.

Comment 19 Arun Raghavan 2013-09-28 03:36:11 UTC
Would it be possible for me to get access to the hardware for debugging?

It's a shot in the dark, but I'm wondering if this might be related to the introduction of priority inversion for non-x86 arches in glibc 2.18. Easy way to check would be with this patch:

Comment 20 Gustavo Luiz Duarte 2013-09-28 23:52:17 UTC
Thanks Arun!
I can confirm that applying Arun's patch both my reproducer and GNOME work fine.

Comment 21 Arun Raghavan 2013-09-29 11:48:08 UTC
Okay, so the problem seems to be related to glibc 2.18's priority inheritance implementation on PPC.

Gustavo, you had a pthread_mutex_* version of the reproducer that worked. Adding this after setting the mutex type to recursive might expose the problem independent of any PA calls:

  pthread_mutexattr_setprotocol(&attr, PTHREAD_PRIO_INHERIT);

Comment 22 Gustavo Luiz Duarte 2013-09-29 19:37:03 UTC
Here is the pure pthread reproducer including Arun's suggestion. It indeed reproduces the issue. It prints OK with glibc-2.17 but hangs with glibc-2.18.

#include <pthread.h>
#include <stdio.h>
#include <unistd.h>
#include <stdlib.h>

pthread_mutex_t mutex;
pthread_mutexattr_t attr;
pthread_cond_t cond;
pthread_t tid;

void *callback(void *arg){
        for (;;){
                printf("Wake up!\n");

int main(){
        pthread_mutexattr_settype(&attr, PTHREAD_MUTEX_RECURSIVE);
        pthread_mutexattr_setprotocol(&attr, PTHREAD_PRIO_INHERIT);
        pthread_mutex_init(&mutex, &attr);
        pthread_cond_init(&cond, NULL);

        pthread_create(&tid, NULL, callback, &cond);

        printf("Going to sleep\n");
                pthread_cond_wait(&cond, &mutex);

Comment 23 Gustavo Luiz Duarte 2013-09-29 19:41:08 UTC
Thanks a lot Arun!

Reassigning to glibc.

Comment 24 Carlos O'Donell 2013-09-30 16:18:50 UTC

Thank you for the pthread reproducer.

Siddhesh, if you need access to a Power box running Fedora 19 please contact me internally via email or IRC and i'll get you access to a machine that exposes this issue.

Thanks Phil, I had an s390 box on which I could reproduce this problem - it's a fairly silly error where I had used the wrong flag (PTHREAD_MUTEX_ROBUST instead of the PTHREAD_MUTEX_ROBUST_NORMAL_NP).  I've posted a patch upstream:


I've also pushed a scratch build for f20.  The srpm upload is taking a while, so I'll share the build URL once it is done.

Comment 28 Phil Knirsch 2013-10-01 13:29:34 UTC
Perfect, thanks Siddhesh!

Shall we propose this as a freeze exception for Fedora 20 Beta? That would allow us to get this bug fixed in primary and then we can include the build for our Alpha.

Thanks & regards, Phil

Comment 29 Siddhesh Poyarekar 2013-10-01 14:50:11 UTC
The scratch build in f20:


I've got a positive review upstream, so I'll push the patch upstream and in rawhide in a while.

Sure, I'll push the patch to f20 as well then, so folks can test and give feedback on bodhi.

Comment 30 Phil Knirsch 2013-10-01 15:31:07 UTC
As per https://fedoraproject.org/wiki/QA:SOP_freeze_exception_bug_process i'm proposing this bug as a Freeze Exception for Beta for Primary as it's a blocker for Alpha for Fedora 20 PPC64.

The fix should be very isolated for PPC64 and S390x, see Siddhesh's comments above.

Thanks & regards, Phil

... and arm, although I haven't actually verified it.  The bug (and the fix) is isolated to non-x86 architectures.

Comment 32 Jens Petersen 2013-10-02 02:13:29 UTC
This also seems to affect building ghc on ppc64 and s390x (bug 989593).

Comment 33 Jens Petersen 2013-10-02 03:59:49 UTC
Hm, I tried building ghc with glibc-2.18-10.fc20.ppc64 but it still
hangs part-way through for me with

#0  0x00001fffffec1ab0 in .pthread_cond_wait () from /lib64/libpthread.so.0

Comment 34 Mike Ruckman 2013-10-02 20:29:25 UTC
Discussed this in the 2013-10-02 Blocker Review Meeting [1]. This has been voted an AcceptedFreezeException. This is a showstopper for PPC64 and while not PA, a tested fix would be considered past freeze.

Comment 35 Gustavo Luiz Duarte 2013-10-02 21:06:12 UTC
GNOME still not working after a default desktop install using latest ISO which includes the fixed glibc:

Same symptom (black screen), though it might be a different issue. This is what I see attaching gdb to the gnome-shell process:

Comment 36 Gustavo Luiz Duarte 2013-10-02 22:37:40 UTC
It looks like it is a different bug. It seems related to gnome-bluetooth.
If I remove all references to bluetooth from /usr/share/gnome-shell/js/ui/panel.js then GNOME works fine.

PS: I didn't see it before while testing the fixed glibc because I had already done the change described above while investigating this issue (now I reinstalled the system). Too many different issues can cause a black screen.

Comment 37 Gustavo Luiz Duarte 2013-10-02 23:57:04 UTC
OK, now we are hitting a gnome-shell bug. Here is the upstream bug: https://bugzilla.gnome.org/show_bug.cgi?id=707430

It has been fixed upstream on gnome-shell version 3.9.92, which is already available on Fedora 20. We just have to pull it on the next RC compose.

So maybe the ghc hang is something else?

Comment 39 Siddhesh Poyarekar 2013-10-03 05:03:04 UTC
Jens, bug 989593 looks like something else not related to this bug.
