FIX#107: Indicator stops working after screen lock

[drivera73]

Added code to handle the case when the name org.kde.StatusNotifierWatcher can't be owned (for whatever reason), and thus the indicators disappear when the lock screen is engaged (manually or otherwise).

This is by no means a final approach, and it may revive some of the side-effects that gave birth to the watchDog object, but I think it's a start.

Just tried this myself, and it seems to work.

Correction: it works for anything that's already open. However, there's still an issue:

• apply this PR's fix
• reload GNOME
• have some programs running in the appindicators
• lock screen
• wake and unlock
• notice that the appindicators still show (the fix in this PR does this)
• open a new program that uses has an appindicator

You'd expect the new app to show up. It does not. You have to restart GNOME again for it to show up.

Ah, actually, this might just be in issue with some apps, in my case, Slack, specifically. Even if I have Slack running, it doesn't show up again after unlocking the computer, like others do. I have to restart GNOME to get it to show up.

The issue has to do with an already-running instance of indicator-application which was mucking up the works. Removed that, and everything works just fine, real-time.

Removed that

I don't fully understand the issue or what you did. Can you explain so I and others can get it working, too? :-)

[drivera73]

In Ubuntu's Gnome there's an "application indicators" program running by default (you can run a "ps -ef | grep indicat" ... or maybe it was "appind" ... I forget). When that program isn't available (i.e its .deb has been removed), then this extension works flawlessly because it's able to own the handle to org.kde.StatusNotifierWatcher

Thus, what you need to do is figure out the following:

1. is that application indicator program running in your system?
2. which .deb installed it ("dpkg -S " should do the trick for you ... you'll need to discover the executable path yourself)

Once you have that, you can remove the .deb, and re-start the Gnome shell, and voilá - this extension will work flawlessly.

Cheers!

Thanks! Here's hoping it works for me, too!
