gnome-power-manager adds battery to indicator twice when battery hot-unplugged and plugged back in

I can confirm this with up-to-date Natty. You might not want to remove the battery when running a 2.6.37-rc6 based kernel, as this can cause a system crash/oops: https://lkml.org/lkml/2010/12/19/90

To reproduce, I simply boot without the battery attached and then attach it while running.

More detal info of my battery ATTACHED.

I posted a patch that fixes that issue, but instead of reviewing it, bugreport was just marked as duplicate of this bug.

The patch is here:
https://bugs.launchpad.net/ubuntu/+source/gnome-power-manager/+bug/616443/+attachment/2083829/+files/debdiff.diff

Thanks for the patch Maxim. I have cleaned it up and placed it in a bzr branch so a dev can merge it. I also tested it and verified that it fixed the issue on Natty. I will need to do the same for Oneiric tonight before proposing both branches for merging.

Any progress on this?

Hi Phillip. I'd go ahead and merge the natty branch, but there are a couple of things that need to be done first:

1. I don't see this fix mentioned in any changelog for the oneiric package, and there has not been any new upstream upload for a couple of months for gpm now.
2. SRU paperwork will be needed to get this into natty. Plesae follow the procedure at https://wiki.ubuntu.com/StableReleaseUpdates.

Unsubscribing ubuntu-sponsors for now.

This patch fixes a highly visible regression in Natty. I recognize that normally SRU policy requires that bugs be fixed in the development release first, but it appears that Oneiric has some serious changes to g-p-m, and the battery indicator does not even show up at all there now, so I can not even confirm that it suffers from the same issue. It sounds like the problem was caused by changes to different components in natty being out of sync, so it is entirely likely that the oneiric updates render this fix obsolete there. I therefore think that an exception should be granted and this patch should be released as an SRU now.

Per comment above, accepting Natty task as it's a regression fix and should go as an SRU.
Rejecting the Oneiric task as g-p-m seems to be quite/completely different in Oneiric and we're not even sure if the issue is also there and if it'd be the same fix to resolve it (currently g-p-m doesn't show any applet in Oneiric and will be replaced by an indicator).

This is invalid in oneiric, as the tray icon / indicator code was removed from g-p-m, with the remaining parts being moved to gnome-settings-daemon

I never removed the battery, i only unplugged and replugged the AC Power Cable, and I get duplicate battery status, on Ubuntu 11.04 64bits.

SRU request:

Impact: Users running natty get a duplicate battery in the power icon when unplugging and replugging either a battery, or the AC power cable. This is a regression from previous releases.

Problem has been addressed with a minimal patch, and update has been uploaded to natty-proposed.

Thanks.

This bug affects me as well on a Toshiba Satellite L505D-S5983. As soon as I unplug my ac adapter I get 2 batteries showing and continue showinf once ac power is plugged back. Its quite the annoyance. I hope the fix gets added soon.

Hello Chow, or anyone else affected,

Accepted gnome-power-manager into natty-proposed, the package will build now and be available in a few hours. Please test and give feedback here. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!

I'm having no duplicates after installing proposed update.

Looks fixed here too, thanks.

The update fixed it. Nice work!

This bug was fixed in the package gnome-power-manager - 2.32.0-2ubuntu2.1

This has fixed the duplicate problem. I still see the "(estimating...)" instead of a battery time remaining when I click on the battery icon in the panel. I am waiting to see if that resolves itself after the g-p-m collects more data or if this issue still remains.

the same problem in Natty 64-bit on Acer Travelmate with all the latest updates...
when does the fix will be released?

@Richard, Jan:
See bug 629258 about that.

Hi guys, I've found a regression on my laptop (Dell Latitude E6500).

Stutus before upgrading to 2.32.0-2ubuntu2.1:
Duplicate entries of the same battery listed but no "estimating" bug.

Status after upgrading to 2.32.0-2ubuntu2.1:
Clicking on g-p-m icon show up two lines: one for my actual battery and one is now an empty string.
If I click on it gnome-power-statistics crashes:

/usr/bin/gnome-power-statistics --device /org/freedesktop/UPower/devices/battery_BAT1
**
ERROR:gpm-upower.c:688:gpm_device_state_to_localised_string: code should not be reached
Annullato

Sideffect: If I unplug AC ubuntu shutdowns because of critical battery (even if the actual battery is full!)

I can confirm the regression that post #23 is having (Dell Latitude D620).

Same problem as post #23 on Dell Latitude 6500
When clicking on the non-existing battery in the power statistics window, the window closes.
I do not have the mentioned side effect though.

For people (like me) that are still having this issue, a fix posted on the redhat bugzilla works on ubuntu: https://bugzilla.redhat.com/show_bug.cgi?id=704110#c12

Fix as linked in #26 fixes the problem here as well, on a Dell E6400.
