Lots of errors from unity-panel-service about gtk_menu_detach flooding syslog

[Jeff Lane ]

I'm seeing a LOT of these messages appear, pretty much every minute or so

for example, the gtk_menu_detach(): menu is not attached message appears in the previous syslog (it just rotated this morning), 1566 times between midnight Oct 9 and Midnight Oct 10, or roughly 1x per minute, or 65 times an hour. And there's no idea what is actually causing that message to occur.

I can't reproduce this cosmic. Can you try reproduce this on cosmic? Also specify how to reproduce? IS it specific to a particular app ?

I am not currently able to try this with Cosmic. This is my primary
workstation and I don't want to get it off the LTS cycle.
Unfortunately, I don't have a second computer that I can install
Cosmic on to try. As for steps to reproduce, I just noticed
something. In the Settings for "Desktop Appearance"/Behaviour, I have
Menus Visibilty set to "Displayed on Mouse Hovering". I set that to
"Always Display" instead, and tried moving the mouse between multiple
windows, but I still get these errors:
Oct 10 11:39:41 galactica unity-panel-ser[27446]: gtk_menu_detach():
menu is not attached
Oct 10 11:39:43 galactica unity-panel-ser[27446]: message repeated 7
times: [ gtk_menu_detach(): menu is not attached]
Oct 10 11:39:43 galactica unity-panel-ser[27446]: gtk_menu_detach():
menu is not attached
Oct 10 11:39:43 galactica unity-panel-ser[27446]: gtk_menu_detach():
menu is not attached
Oct 10 11:39:46 galactica unity-panel-ser[27446]: message repeated 7
times: [ gtk_menu_detach(): menu is not attached]

Likewise, when I run unity-tweak-tool and click between tabs within
the window, those errors are generated.

In unity tweak tool, under Window Manager / General / Additional,
mouse focus behaviour is set to Sloppy (focus follows mouse). Setting
that to "Click" slightly changes the behaviour in that the error isn't
generated until I click inside a window to focus it. So the behaviour
seems to be tied to focusing windows, or perhaps a redraw that's
triggered by the focus grab.

But that's the best I can tell you, I'm not super knowledgable about
how window management works.

I can't reproduce this on bionic either. The error something related to compiz/unity is broken. Do try installing ubuntu-unity-desktop to see if any package is missing. If you have upgraded from 16.04 then it could be the issue with compiz profile broken. Check askubuntu answer how to reset compiz.

And about testing, you can check with live usb Make a persistent live usb, boot from it and install ubuntu-unity-desktop.

Btw unitu-tweak-tool is not maintained at the moment. Instead try ccsm.

Status changed to 'Confirmed' because the bug affects multiple users.

[Antonio Cunei (bendreth)]

I have the same message, and in my case it is "indicator-power-service". The messages only appear when on battery, and stop if I kill the indicator.

[Khurshid Alam (khurshid-alam)]

@Antonio Cunei

What are your power settings in unity-control-center ?
