awn uses 100% cpu with gtk+ 2.17.3 (csw)

[Bmw1000c]

Binary package hint: avant-window-navigator

when awn is opened, cpu usage raises to 100% which leave the system completly unoperable

a lot of errors in .xsession-errors:

The same problem with the version from:

Which window manager are you running?
Which version of the nvidia drivers do you have installed?

What level of "visual effects" is your desktop configured for?
(See System -> Preferences -> Appearance -> Visual Effects, I believe. Not running Ubuntu at the moment.)

[Bmw1000c (bmw1000c)]

normal.

i used awn for about 2 weeks and then, with the yesterday's update, it was using 100% cpu

[Wayne Cat (exchange)]

Forgot this:

- I'm using Gnome with Compiz
- Visual Effects: Normal
- ATI Technologies Inc M56P [Radeon Mobility X1600]
- xserver-xorg-video-radeon 1:6.12.99+git20090629.f39cafc5-0ubuntu1

[Tjeremiah (tjeremiah15)]

I can also confirm this. Recent update made the cpu blow up to 100%.
- Compiz with Gnome
-Visual Effects : Extra

[Mark Lee (malept)]

It would be great if you all could remember what was upgraded in the update in question.

Additionally, please try the following (as I have a feeling that it has something to do with compiz):

1. Press Alt + F2. This will open up the "run program" dialog.
2. Run the following command (without quotes): "metacity --replace --composite"
3. This will replace Compiz with the default window manager for GNOME, Metacity, but with composite enabled (so that Awn runs correctly).
4. Start Awn. Does Awn still use 100% of your CPU?

[André Ventura (afv)]

I can also confirm this. There were some updates to some libgtk2-* packages yesterday (2.17.3-0ubuntu1)…

- Ubuntu / Gnome
- Compiz / Visual effects: custom
- NVIDIA: 190.09
- Kernel: 2.6.31-2.17
- AWN: 0.3.2.1-4

Same problem after trying with metacity (metacity --replace --composite).

[Wayne Cat (exchange)]

I have attached a list of updates. The problem started after theses upgrades.

[Mark Lee (malept)]

@Wayne Cat: Thank you for the list of updates, that helped a lot.

@all affected:
So what I'm thinking is that given the variety of video cards/drivers and window managers, and also the upgrade list provided by Wayne Cat, that this is a problem caused by the most recent upgrade to GTK+.

To test this theory, I need you all to downgrade all of the packages in Wayne Cat's updates list with the version "2.17.3-0ubuntu1" (they all have "gtk" in the package name) to a version lower than that According to Launchpad, the version immediately preceding that one in Karmic is "2.17.2-0ubuntu2". Details on downgrading packages can be found in the following Ubuntu Forums links:

Downgrading libgtk2.0-0 from 2.17.3-0ubuntu1 to 2.16.1-0ubuntu2 "solves" the problem.

[Wayne Cat (exchange)]

Thanks André V and Mark Lee... good job!

I have tried your "solution" ... "solved" my problem too. Maybe the awn developer knows what we should do to use
awn with the new libgtk2.0-0 version.

[André Ventura (afv)]

I'dd also like to add that this new version of libgtk2.0-0 crashes cheese upon start… Maybe it's not AWN nor cheese's problem.

[André Ventura (afv)]

[Mark Lee (malept)]

Sharkbait in IRC reminded me that the major change in GTK+ 2.17.3 is the merging of the client-side-windows branch, which is effectively a rewrite of how GDK (the underlying, platform-specific part of GTK) works. Awn (and apparently, Cheese as well) does not work with this rewrite.

[André Ventura (afv)]

(Sorry for the double post. Didn't stop the page in time.)

A user from Ubuntu Forums referred that it is working with 2.17.2-0ubuntu2 too. This should help a little more.

I didn't test that version because it isn't at http://mirrors.kernel.org/ubuntu/pool/main/g/gtk+2.0/ .

[Wayne Cat (exchange)]

Marc Lee ... thank you for the "background information"

I'm using the Screenlets "Output applet" (Widget-like mini-applications for GNOME) ... it also has problems with the new version. Not critical ... it works ... just lost the "3d look" ... but maybe other tools also have problems with the update ... just for your information.

Attached ... my .xsession-errors ... maybe the Screenlet developers will have to change their code too.

BTW ... major changes means ... major improvements ... awn is not critical application ... And I did not see major gtk
problems in the Ubuntu Karmic testing forum.

[Mark Lee (malept)]

See also bug #398250 for another app that doesn't work with the GDK rewrite (and I'd call that app critical...).

[Sebastien Bacher (seb128)]

Thank you for your bug report. The issue is an upstream one and it would be nice if somebody having it could send the bug the to the people writting the software (https://wiki.ubuntu.com/Bugs/Upstream/GNOME)

[Sebastien Bacher (seb128)]

the issue could be one of the ones fixed in 2.17.4 which will be uploaded tomorrow

[ThaBiGGDoGG (thabiggdogg)]

I am not sure if this is related into this but after that update that messed things up when I reboot & log into my system I now get a "Gdm-simple-greeter" error. On top of the window says Metacity.

[Wayne Cat (exchange)]

Tha BiGG DoGG,

this problem is related to the new gdm 2.26 version. See #395324 for further information.

[Sebastien Bacher (seb128)]

Confirmed on 2.17.4 in karmic and sent on http://bugzilla.gnome.org/show_bug.cgi?id=588438

[Mark Lee (malept)]

Attention Karmic users:

Upstream has asked for a stacktrace. Here's the (relatively) quick way to get it:

1. Install bug-buddy and the debug packages for GTK and libawn: `sudo apt-get install bug-buddy libawn0-dbg libgtk2.0-0-dbg`
2. Run Awn from the terminal, with bug-buddy enabled and configured to run when the critical message is encountered: `GTK_MODULES=gnomebreakpad G_DEBUG=fatal_criticals avant-window-navigator`
3. When Awn crashes, save the bug report somewhere. (In case that there's more than one of the "save bug report" dialogs, the one we want is the one which lists the default filename as "avant-window-navigator-bugreport.txt".)
4. Attach that bug report to this bug.

Thanks in advance. The Awn developers really want to get this resolved.

[Bmw1000c (bmw1000c)]

how do i configure bug-buddy to run with that message? thanks

[Wayne Cat (exchange)]

Sorry ... stack trace not possible ... "unfortunately" awn does not crash ... after about 30 minutes
( Xorg at about 60% and awn at about 30% CPU usage) I had to kill the awn process. No result
from bug-buddy.

[Mark Lee (malept)]

IIRC, bug-buddy doesn't need to be configured at all.

If you run the command in #2 in the terminal exactly, it should "crash".

To reiterate, the command to run is as follows:

GTK_MODULES=gnomebreakpad G_DEBUG=fatal_criticals avant-window-navigator

[Wayne Cat (exchange)]

ok ... bloody typo ... here it is.

@ Bmw1000c and Wayne Cat:

1. Are you positive that libawn0-dbg is installed?
2. Could you confirm that the bug still exists with GTK+ 2.17.5 (recently added to Karmic)?

[Bmw1000c (bmw1000c)]

1. yes i am. i run "GTK_MODULES=gnomebreakpad G_DEBUG=fatal_criticals

FYI, that patch is in GTK+ 2.17.6:

I have installed GTK+ 2.17.6

The error messages in .xsession-errors are gone ... but still 100% CPU usage (awn & Xorg process)

[Mark Lee (malept)]

Yeah, I kind of figured.

FWIW, we (the Awn devs) are waiting for the GTK devs to respond to a performance analysis that was attached to the bug last week.

[Julien Lavergne (gilir)]

I pushed a workaround found by mhr3 for this problem, it's available in my PPA : https://launchpad.net/~gilir/+archive/updates

I confirmed that the bug is gone, but more testing will be appreciate to see if this workaround doesn't generated more bugs.

[Michal Hruby (mhr3)]

What could happen with this patch is that the icons will be below the dock itself, please let us know if this seems to be happening.

[Wayne Cat (exchange)]

Julien,

your version works great on my system. AWN works like expected and the CPU usage is low.
I will use it to see if there are any bugs in it.

Michal,

the icons in my dock are were they should be but I will keep this in mind.

This package this the problem on my computer after reinstalling AWN
package from universe repository.

However (but I should search if there is an other existing bug for that)
there is a with compiz when preview's thumbnail plugin is activated :
when it should draw the thumbnail compiz crash. This is true with both
awn packages (from Julien's ppa and universe repository).

Offhand, this doesn't look like it's relevant to this bug (or to Awn, for that matter). You probably want to file a compiz bug (if one doesn't already exist).

[Moisa Doru (moisadoru)]

Yup, this one works for me

The Awn developers are marking this as "Invalid", as the regressions have been fixed upstream in GTK+ (without any changes in the Awn package). Thanks to the reporters who helped debug this.
