openQA sees the same and fails because of this: https://openqa.opensuse.org/tests/1415989#step/first_boot/1

This didn't happen with Plasma 5.19.5:

Reassigning to Nate, who touched it last :P

Does this mean that you had unchecked that checkbox to work around a bug whereby the old popup always opened on login? Or was it not happening before and it just started happening now?

At least in openQA it runs with default settings. With Plasma 5.19.5, there is no popup on login (just the icon is there) and with the 5.20 Beta there is a popup on login.

Got it, thanks.

"Open popup when new device is plugged in" was unchecked on my system before update to Plasma 5.20 beta, exactly to prevent the behavior of Plasma 5.20 beta. It worked as expected,
that is, no popup after login or plasmashell restarting.

Thanks.

Is there any way to simulate having an optical drive? None of my Linux computers have one. I can debug in a live ISO on a Windows desktop, but that will probably take longer.

I don't think it has to be an optical drive. Any removable drive should do,
as long as it shows up in the notifier.

Ah, so the bug is more generic such that the pop-up should not appear if the external $thing is already present at boot. I did notice this while porting the applet but did not register it as a bug.

If people do consider it a bug, I can fix it.

At least I consider it a bug. It's not too uncommon to have semi-permanently attached storage, some even boot from it. (Though udev rules could be used as a workaround for that).

While it's not as much of a distraction/obstruction to people as it is currently to openQA, I don't see much value in showing the popup directly after login or plasma restarts/crashes.

So unless it's something which needs considerable work (I couldn't immediately spot the culprit), I'm in favor for restoring the old behaviour.

Fair enough. I'll see what I can do!

[applets/devicenotifier] Don't open popup for already-connected devices

The old applet only opened the popup when a new device was attached
after the applet was loaded, not if there was already a device attached
when the applet was loaded. This commit brings back the old behavior by
re-using the approach taken in the old applet.
