Description Robert Orzanna 2014-10-14 09:18:18 UTC
I am running wnck, bamf together with plank on a plain Openbox system. In my journalctl log I receive hundreds of the following messages:

Okt 13 21:53:59 thinkpad org.ayatana.bamf[1140]: (bamfdaemon:1208): Wnck-WARNING **: Unhandled action type _OB_WM_ACTION_UNDECORATE
Okt 13 21:54:41 thinkpad org.ayatana.bamf[1140]: (bamfdaemon:1208): Wnck-WARNING **: Unhandled action type _OB_WM_ACTION_UNDECORATE

Okt 13 22:00:38 thinkpad org.ayatana.bamf[1140]: (bamfdaemon:1208): Wnck-WARNING **: Unhandled action type _OB_WM_ACTION_UNDECORATE

I tried to discuss the issue at the bamf bugtracker but have not received any response there yet [1].

On the Arch Linux bugtracker I was pointed out that this is not a bamf issue but related to wnck [2].

As far as I understand the error message correctly, wnck does not support WMs such as Openbox. Could this support be added to avoid these error messages?

Additional info:
* package version(s)
* config and/or log files etc.

bamf 0.5.0-3
plank-bzr r1094-1
openbox 3.5.2-7
libwnck 2.30.7-2
libwnck3 3.4.9-1

I don't think this is actually a warning you should care about.
This action is not supported but by OpenBox, and there's no much more we should do at libwnck level.

So I think is quite safe to ignore it.

@Marco

Should/can something be done at the Openbox level?

I would be perfectly fine with ignoring it if it was only a few of these warnings, but it is bloating up my journal log extensively,
Comment 3 Marco Trevisan (Treviño) 2014-10-23 12:59:56 UTC
At our level we might deescalate the message to debug level maybe, but still I guess you just have to set the G_MESSAGE_DEBUG var at the proper level to filter these out.

Would be very much appreciated, thank you.

> guess you just have to set the G_MESSAGE_DEBUG var at the proper level to
filter these out.

Could you give me an example how to do this? I checked the web but could not find any relevant information on the proper use of G_MESSAGE_DEBUG.
