Bug Description

After recent updates a second network-manager icon appeared in panel (screenshot). (similar with battery few days ago)

it's likely yesterday's nm-applet updates ... mathieu, those users do whitelist all systray icons in unity so they get fallback icons showing if they are not probably hidden

There is no dupe nm-applet symbol on pc, which is connected with lan, but also has systray whitelist 'all'.
Updates are the same as on laptop.

Not just Unity - seeing the same thing in Xubuntu.

#6 was a fluke. Yesterday I could observe the moment I've activated suspend on pc a second network icon appeared before the screen turned off.

On pc after several reboots and logouts (due to some other testings) it displays only the orig. network icon.
On laptop it still displays network icon twice after several reboots and logouts. Update status is the same on both computers.

Bunch of updates later and now I have no network notifications at all.

And that's for Xubuntu in all these cases? It seems rather weird because the GtkStatusIcon should never show unless the indicator is in fallback mode... in fallback, it's shown, every other moment it should be hidden; though I may have screwed up one case in the last nm-applet upload.

Report was made from Unity, added the tag. On pc it definitely adds a second icon when going to suspend. When I reboot the pc it displays one icon. On laptop the second wl icon is always there.
Among the first lines of .xsession-errors it says:
** Message: applet now removed from the notification area
Initializing nautilus-gdu extension
** Message: using fallback from indicator to GtkStatusIcon
Initializing unityshell options...done
** Message: applet now embedded in the notification area

Yeah, I know what went wrong. There's one oversight in the code to handle disabling the icon -- one of the gtk_status_icon_set_visible() calls were not wrapped properly with a test to see if the widget should be shown. I've corrected that, and I'll upload the fix soon.

Thanks Mathieu.

I assume that will fix it for all and not just Ubuntu/Unity - if not report here or create a new bug for Xubuntu?

Sam_ (and-sam) wrote :

Thanks Mathieu, that would be one of a kind of turbo fix!

Tom Pino (metalsmith-rangeweb) wrote :

Well as for today there is no applet at all under Xubuntu.

I am pretty sure my connection is up and running well. Would have been hard to get this page up if not.

Should we file another bug or is this good enough?

I also have no indicators in either the indicator or notification areas of the panel with Xubuntu 12.04 using Networking is functional but have no desktop control.

I've downgraded to a previous release where the icon is only displayed in the notification area of the panel.

This bug was reported while running Unity and having two icons displayed, the commit isn't yet uploaded.
Regarding Xubuntu and having no applet at all displayed imho is a different story.
That said the last release obviously has different outcomes on different environments.

Elfy (elfy) wrote :

Totally agree Sam_ - as soon as the fix is released etc I will look - if it needs re-reporting I'll do so - but no point in duplicates until sure :)

The solution here is to add Unity to NotShowIn in the .desktop-file:

Sorry, just noticed that both network icons disappeared :(

With the nm-applet upload, a GConf key was introduced to show/hide the applet in the systray: '/apps/nm-applet/show-applet' and its description is: 'Show the applet in notification area'. and 'Set to FALSE to disable displaying the applet in the notification area.'.

That's why I set this key to FALSE in xubuntu-default-settings 12.04.7...

And obviously the documentation is wrong, because this key will hide it from everywhere (both the systray and the indicators).

So if you use Xubuntu 12.04, you can set back this key to TRUE with gconf-editor to let the nm-applet reappear. (Until I revert my change in the next upload).

@Mathieu Trudel-Lapierre (mathieu-tl): See above, please fix the gconf description of the key. Thanks!

Lionel, the description isn't really wrong -- the expectation is that the gconf key hides both the indicator and the GtkStatusIcon, because they are never supposed to show at the same time -- one being the fallback of the other. The fact that they did is the symptom of this bug.

Fixing the underlying bug will cover the issue.

Thanks for fixing the bug. I still needed to set the nm-applet value to TRUE through gconf-editor to make it show up. I am assuming that this is because it had been set to FALSE as Lionel described above.


Correct, that change will also need to be reverted.

Elfy (elfy) wrote :

While I have it setup now here and it works correctly - I wonder if a bug for xubuntu needs to be raised as to show it there you need to install gconf-editor to allow the applet to show.

Or is there something else in the pipeline that would negate this?

Lionel Le Folgoc (mrpouit) wrote :

Gconf-editor isn't really needed, you can do it with: "gconftool-2 -s /apps/nm-applet/show-applet -t bool true" too.
Anyway, Micah has just uploaded xubuntu-default-settings 12.04.8 reverting the change, so nm-applet should be visible again.
