+1 if you can't find any software issue,

but don't run memtest, disassemble and mount the RAMs again. If you've
got several RAMs, remove just one after the other. It could be that for
non-audio work most of your RAM isn't needed, but audio streams might
need much more RAM.

Do you get any additional output, when you launch ardour2 and jackd in a
terminal emulation?

A core dump might be useful too, if you get a segfault.

Goodmorning,

I made a memtest all night but it found no errors to my memories.

Also there are these files in the /dev/shm folder. Could you explain why should
I remove all pusle files? Do they cause any conflict with the programm?

alex@Kubuntu-pc:/dev/shm$ ls
libv4l-alex:usb-0000:00:04.0-1:093a:2460:CIF Single Chip
pulse-shm-3932302597 pulse-shm-2471209672
pulse-shm-927429857 pulse-shm-269307697
pulse-shm-949059306
alex@Kubuntu-pc:/dev/shm$

Furthermore, I get this on my terminal when I run qjack and it runs perfectly.
Can you find something suspicious here?

alex@Kubuntu-pc:~$ qjackctl
QInotifyFileSystemWatcherEngine::addPaths: inotify_add_watch failed: No such
file or directory
QFileSystemWatcher: failed to add paths: /home/alex/.config/ibus/bus

Finally, (sorry for the long text!) I paste this text among others which I get
when I run "strace ardour2". Could somebody assess all this information?

Is your disk full? "df -h" should tell you.

You may also want to remove the .deb that is cached in
/var/cache/apt/archive before you reinstall.

Is there anything in /var/log/syslog that shows up at the same time
you try to run ardour?

You wouldn't happen to be over-clocking this computer would you?

That's why I mentioned to check the RAMs by trail and error, disassemble
and mount back again, one after the other.

I've got 4GB RAM on a 2.1 dual-core machine, I need to run the test 24
hours or longer, just running it some hours I'll might get just a few
passes.

Did you upgrade packages for plugins? Perhaps a plugin is broken?

I would launch ardour2 and jackd (not qjackctl) in separated terminal
emulations.

And again a '...fault' is better than just an app that quits without a
'...fault', because you can get a core dump.

I don't remember what exactley to do, fortunetly I didn't need it for a
loooooooong time, AFAIR you need to run

sudo ulimit -c [some value]

and then

gdm ardour2 [something_else]

but I might be completely wrong , please google yourself, I'm short in
time, sorry.

Hth,

Ralf

I tried it, but no improvement.

But yes, I found this on syslog whenever I try to run ardour:

May 31 00:40:18 Kubuntu-pc kernel: [19300.148249] ardour-2.8.11[4134]:
segfault at 50 ip 00007f3d8b788d1c sp 00007fff7c3d4f80 error 4 in libgtk-
x11-2.0.so.0.2400.4[7f3d8b599000+436000]

Could somebody guess what to do with this? Should I try reinstalling
something?

Also, I just remembered that the day that the problem started with ardour I
had installed 3 gstreamer plugins that the system notified me to do in order to
optimize Amarok's performance. It described them as ugly, bad and super bad
correspondingly as far as I can remember. Do you think that it could have
something to do with ardour not launching? If yes how can I see which
particularly plugins I have installed in order to remove them?

Thank you all! Any ideas?

Alex

I'm subscribed to Ardour users mailing list. I recommend that you do the
same .

http://lists.ardour.org/listinfo.cgi/ardour-users-ardour.org

More shots in the dark just would lead into the wrong direction.

Allright guys,

I have just fixed the problem...with a trial and error method!

I started unistalling one-by-one the packages that I have installed the last 3
days and I kept testing if ardour could launch each time I uninstalled
something.

When I uninstalled "pavucontrol" ardour launched perfectly!! I also
uninstalled with autoremove "libcanberra-gtk-module" and "libcanberra-gtk0"
that pavucontrol automatically installed and which might caused the problem in
libgtk-x11-2.0.so.0.2400.4, as syslog was informing me whenever I launched
ardour.

Thank you all for your help and time!

Best regards,

Alex

I have no clue. If I'm not mistaken, none of the packages that provide that file
has changed recently.

To make sure, could you:

$ dpkg -S libgtk-x11-2.0.so.0.2400.4

...and then run `ls -l <full_path_to_each_occurences>' and post the results
here. For example, here's what my system shows:

jaska@ardbeg 02:12:21 ~$ dpkg -S libgtk-x11-2.0.so.0.2400.4
libgtk2.0-0: /usr/lib/libgtk-x11-2.0.so.0.2400.4
ia32-libs: /usr/lib32/libgtk-x11-2.0.so.0.2400.4
jaska@ardbeg 02:12:44 ~$ ll /usr/lib/libgtk-x11-2.0.so.0.2400.4
-rw-r--r-- 1 root root 4461064 2011-04-14 21:15
/usr/lib/libgtk-x11-2.0.so.0.2400.4
jaska@ardbeg 02:13:19 ~$ ll /usr/lib32/libgtk-x11-2.0.so.0.2400.4
-rw-r--r-- 1 root root 4023088 2011-04-14 20:48

I have no idea how those plugins might have affected such a library, but better
safe than sorry. You can check your dpkg log at: /var/log/dpkg.log

It should be quite obvious if you start from the bottom end, you should see the
latest installed packages.

Might even give us a look, unless you have anything you don't wanna share with
us by:

$ tail -20 /var/log/dpkg.log

Right, I'm no GTK expert, so I asked from the bug squad for some assistance.
Looks like you should file a bug against libcanberra. But the squad wants to
know, is this an amd64 or i386 machine?

Thanks for the info! Hope you have patience still to help us resolve the issue.

Hello!




My machine is amd64. However I noticed the following message of Ardour regarding the canberra-gtk-module when I launch it from the terminal (in bold relative with the specific module):




alex@Kubuntu-pc:~$ ardour2

Ardour 2.8.11

(built using 7387 and GCC version 4.5.1)

As it is mentioned, Ardour tries to load it but can' find it since I have uninstalled it. But if I try to install it, then Ardour will not launch at all.




So, I can' figure out what is happening here, but since I can work with Ardour then this is not a big deal! If you have any more information on this, I would love to hear it! If you need any more information, I am at your disposal. Thank you once again!




Best Regards,




Alex
