5. Use is inactive for more than 5 minutes, and less than 15. (At 15
minutes it definitely goes into suspend successfully).
6. I look up and see the GNOME lock screen with multiple yakyak
notifications, and also see a power notification (international stop
sign symbol). The power notification doesn't itself make the display
come on, it's yakyak. If I don't receive an incoming message on
yakyak, I have no idea the power notification is present. And if I
take a screenshot while the display is off, the screenshot file is all
7. The instant I click on any key or the trackpad, only the power
notification vanishes. The yakyak message remain in the list, and once
I log back into my user session, the power notification is not in the
drop down list of notifications when clicking on the time. And yet all
the yakyak notifications are in the list.
That is the expected behaviour. gnome-settings-daemon dismisses the
notification about the imminent inactivity suspend when the user
becomes active again.
So that *is* currently the expected behaviour, even if it also seems
kind of pointless to me to show this warning (without proper
information) on the lock screen.
There are also the following bugs, which would enable you to disable
the power related notifications completely:
but that does not really address the issue you are raising.
