Notification LED stays on when no messages in notification center

[John Lenton]

Observed the notification LED staying on even though there were no notifications in the indicators and the notification icon was greyed out.

[Nick Dedekind (nick-dedekind)]

There is a possibility that if unity8 crashes while the light state is set, then it can keep that state if u8 comes back up with no notifications.

We need to decouple the usage from the lights plugin from the messaging indicator widget so that it will keep the lights state up to date.

This is marked as fixed for vivid, but I'm still seeing this on vivid-proposed image 77 mako.

[Michał Sawicz (saviq)]

Ken, can you post steps to reproduce if you find them? Potentially as a different bug?

[Ken VanDine (ken-vandine)]

Not sure really, with the screen off and no notifications in the indicator the light blinks.

[Ken VanDine (ken-vandine)]

An observation, what I'm seeing on vivid isn't just the LED, the messaging indicator icon actually isn't being changed after clearing the notifications. This is what's keeping the LED lit, it just follows the status of the icon. So the bug I'm seeing is actually the notification icon not changing when the indicator is cleared.

[Michał Sawicz (saviq)]

That would be the messaging indicator then. Or! If you wait for a second or two, I've seen the items coming back into view after all, maybe you're seeing the same?

[Niklas Wenzel (nikwen)]

Ken, I guess you're talking about the following bug: https://bugs.launchpad.net/ubuntu/+source/indicator-messages/+bug/1412779
Would be nice if you confirm it. :)

[Michał Sawicz (saviq)]

This is now on the indicator-messages side, IIUC it should hide from the panel if there are no unread messages? Whether it should change the icon (grey vs. white-ish, on which the LED state is based on) I'm not sure?

[Niklas Wenzel (nikwen)]

@saviq: It currently doesn't seem to recognize when messages are cleared. Therefore, the icon stays white (=> unread messages) and the LED stays on.

That's what https://bugs.launchpad.net/ubuntu/+source/indicator-messages/+bug/1412779 is about.

[Launchpad Janitor (janitor)]

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

[Ted Gould (ted)]

Seems to be related to the push-client, were I think this might be an i-messages bug is that we're not showing the offending tweet (in this case). The push-client doesn't seem to be responding to the clearing if items.

[Niklas Wenzel (nikwen)]

I also noticed SMS notifications are cleared fine, with the LED turning off.

[Ted Gould (ted)]

Okay, to recreate. Start up the device. Send this from ADB shell:

gdbus call --session --dest com.ubuntu.Postal --object-path /com/ubuntu/Postal/com_2eubuntu_2edeveloper_2ewebapps_2ewebapp_2dtwitter --method com.ubuntu.Postal.Post com.ubuntu.developer.webapps.webapp-twitter_webapp-twitter '"{\"message\": \"foobar\", \"notification\":{\"card\": {\"summary\": \"yes\", \"body\": \"hello\", \"popup\": true, \"persist\": true}}}"'

Then on the messaging menu select "Clear All". Notice the tweet is removed from the list but the envelope remains signaling new messages.
