[hardy] Two instances of applet icon are displayed in notification area

Bug Description

The subject says it all.

After switching to battery power in a shot while I observe two Power Manager icons in the notification area. Both "icons" seem to provide different information, e.g. estimated battery life/charge time differs by 5 minutes.

I am running up to date Hardy amd64 on the following laptop: https://wiki.ubuntu.com/LaptopTestingTeam/DellInspiron640m

I observe similar behavior on a Thinkpad X41 Tablet running Hardy. gnome-power-maanger behaved as expected (one battery icon when on battery power) on this same machine under Gutsy.

Both of the icons on my machine seem to show the same estimated run time, though.

Thanks Rick, I will mark this as Confirmed. Are you and Alexey still experiencing this issue?

Changed in gnome-power-manager:
importance: Undecided → Medium
status: New → Confirmed

Currently, I am using 32-bit Hardy (had to switch because of some commercial software not working properly under 64-bit), where I do not observe the reported behavior.

Correction: Yes, I still observe it.

I also see the behavior on my Thinkpad X41 with a fully-updated (as of today) Hardy.

It's intermittent - happens most often after a suspend/resume cycle or two. Anything we could do to try and track down what's causing this?

It's happening on my HP nc6220 with Intrepid x86. I can trigger it by running "gksu update-manager" from the Run Application window.

It looks like I have this bug on my laptop Thinkpad T61 with Intrepid.

Still a bug in Jaunty as well. If you run gksu update-manager, a second gnome-power-manager applet appears and won't go away unless you use sudo killall gnome-power-manager.

I also have this issue on an Acer Aspire 6930 running karmic 64 bit.

I have the same bug in Ubuntu 11.04 (actually Lubuntu 11.04 but it uses afaik the same applet) with a Thinkpad X40. It also showed up after a suspend/resume.

This seems to be one of the really long-living bugs!

After I updated to 11.10 I now also have two icons in my panel. They seem to be a little bit different (the left one I can't click on and it looks a little smaller than the "real" one). Also, both symbols display the battery as empty all the time (red battery symbol).

I had the same issue (Oneiric), it disappeared as soon as I removed the ['all'] entry from the systray-whitelist that I had previously added for some non-standard systray indicators to appear. Do you also have made such a change?

Christian Theune (ctheune) wrote :

I remember something in 11.04 when unity was introduced. I remember manipulating that whitelist to allow older programs to appear and to work around a bug that kept the icons' menus appear except when clicking twice.

I guess that setting is still in effect. Couldyou remind me where 'systray-whitelist' can be set?

You can check your setting with:
  $ gsettings get com.canonical.Unity.Panel systray-whitelist
The default values are:
  ['JavaEmbeddedFrame', 'Wine', 'scp-dbus-service', 'Update-notifier']
In my case this had been changed to "['all']"
If you have it installed, you can also use dconf-editor to check/set the value.

I followed a blog post like this back then: http://www.webupd8.org/2011/04/how-to-re-enable-notification-area.html

Ok, thanks - good call. That fixed it. I'm removing the oneiric tag from the subject.
