Multiple tray icons on Kubuntu 20.04 #1770

Forinil · 2020-09-30T11:40:48Z

Describe the bug

Multipass started showing multiple icons in system tray. Only one of them works correctly, the rest shows Failure retrieving instances

To Reproduce

Unfortunately, I do not know how to reproduce this. I installed Kubuntu 20.04 and mutlipass shortly after the former came out. I did not experience any problems initially. I only noticed the additional icons a couple weeks ago. I update my system regularly using apt.

Expected behavior

A single, working multipass icon in the system tray.

Additional info

ps -ef | grep multipass (while two tray icons are shown)

Hi @Forinil,

Did you add Multipass to your auto-started apps manually? Snapd handles it through its own userd daemon starting with your session.

Forinil · 2020-09-30T12:59:09Z

No I did not. I installed it with snap and left all the settings default.

Saviq · 2020-09-30T15:58:54Z

Something KDE is doing must be triggering the one with the -session argument… Is the other instance (--autostarting) working fine?

Forinil · 2020-10-02T19:27:08Z

In general yes, though one time it crashed - there was no text in the menu and no way to get rid of it, other than killing the process. But that time the CLI did not work either and after a restart everything went back to normal - that is I still had two icons, but the --autostarting one worked fine, even after quitting the other one.

Forinil · 2020-10-06T12:19:10Z

So yesterday I had the same issue with no text in the menu and multipass not working at all and today there's only one icon and everything works fine.

There seems to be no rhyme or reason to this.

MrJamesEllis · 2020-10-07T09:26:01Z

Hi

My KDE Neon 20.04 has this issue as well.. except it has 3 icons.

Haven't done anything apart from the bog-standard install and there is nothing I can see in KDE's autostart/startup.

2 icons show "Failure retrieving instances" on right click and the other shows the machine name. All 3 do nothing on left click.

Happy to poke around relevant system locations that could hold clues, if someone could out where they are.

ricab · 2020-10-07T10:05:20Z

Hi @Forinil, @MrJamesEllis, that -session argument is unfamiliar to us. I suspect KDE could be trying to restore an earlier session and running things on its own. Do you have it configured to restore sessions?

Also, what does the following say?

for pid in `pgrep multipass.gui` ; do echo --- $pid:; pstree -alsp $pid ; done

@MrJamesEllis I titled this issue Multiple tray icons... because, while I usually have only two icons, I had three icons show up once or twice as well.

ricab · 2020-10-07T12:57:18Z

Thank you @Forinil. And another piece of info if you may, to help us figure out how best to approach this: can you confirm that, if you kill the multipass.gui process(es) that have -session in their cmdline, the remaining icon (the one with --autostarting) behaves properly?

Forinil · 2020-10-07T14:11:04Z

@ricab I was already asked this question. My answers were

In general yes, though one time it crashed - there was no text in the menu and no way to get rid of it, other than killing the process. But that time the CLI did not work either and after a restart everything went back to normal - that is I still had two icons, but the --autostarting one worked fine, even after quitting the other one.

So yesterday I had the same issue with no text in the menu and multipass not working at all and today there's only one icon and everything works fine.

There seems to be no rhyme or reason to this.

By the way - today two icons again, one working and one not.

ricab · 2020-10-07T15:06:52Z

Ah ok, I missed that. It would still be useful to make sure it is always that one that works (and not just the one that starts first, for instance). But it should be, if we got it right.

Saviq · 2020-10-07T17:58:35Z

Hi all, @ricab implemented a workaround in #1791, which will prevent the icon from starting if it's invoked with the -session argument.

In a few minutes you should be able to test with Multipass from the edge/pr1791 snap channel.

As far we can tell, it is KDE trying to restore the icon on session startup, which it shouldn't do, and certainly not the way it does it (outside of the snap environment).

Forinil · 2020-10-08T16:13:56Z

I did a test and started manuallu quitting multipass.gui before shutting down the system and the second, non-working icon stopped showing up. I guess this proves @ricab theory about KDE trying to restart the session.

I switched the snap to channel edge/pr1791. So far there seem to be no issues, other than multipass.gui not being restarted automatically by snap refresh multipass --channel=edge/pr1791. I had to restart it manually to get it to work.

Saviq · 2020-10-09T06:33:46Z

I had to restart it manually to get it to work.

Correct, this functionality is in progress in snapd, see:

https://forum.snapcraft.io/t/wip-refresh-app-awareness/10736

1791: [gui] Refuse session restoring r=Saviq a=ricab Hopefully fixes #1770. Qt consumes `-session <id>` from the command line before we have a chance to parse it. When we parse the `QApplication::arguments()`, it's no longer there, so we continued happily. But then we were not running with a proper environment, so no luck reaching the daemon. Since we don't implement session restoring, we need to explicitly refuse the attempt. This is only applicable to `QGuiApplication`s, so it does not affect our other binaries.

MrJamesEllis · 2020-10-15T09:41:24Z

I know this is closed and all, I've been away and have only just been able to test this. Using the edge/pr1791 refresh, signing out and signing in again there is only one multipass.gui icon and it was able to start the instance.

Interestingly, right clicking on the icon after closing the instance shows a context menu with not text, I don't think it's related to this issue, tho:

FTR, here are the results of that command prior to refreshing from edge/pr1791

Hi @MrJamesEllis, thanks getting back to us. So everything is as anticipated regarding this issue and I am glad it's working for you now.

On the menu with no text, yeah that would be a separate problem. Do you observe that consistently, or was it a one-off thing? Did you perhaps get that after the snap refresh, for a previously running GUI? Feel free to open a new bug report.

1791: [gui] Refuse session restoring r=Saviq a=ricab Hopefully fixes #1770. Qt consumes `-session <id>` from the command line before we have a chance to parse it. When we parse the `QApplication::arguments()`, it's no longer there, so we continued happily. But then we were not running with a proper environment, so no luck reaching the daemon.
