Created attachment 175415 [details] this shows how the settings SHOULD look but only appears this way when there are pending updates SUMMARY since updating to kubuntu 24.10 (and plasma 6) the discover icon is no longer displayed in the system tray, or in the systems tray settings window, unless there are pending updates. it is as if the visibility settings were set to "Shown when relevant" but some how that setting is also applied in the settings window. STEPS TO REPRODUCE 1. go to systems tray settings and look for Updates entry 2. wait for pending updates to become available for install 3. go back to systems tray settings and look for Updates entry OBSERVED RESULT at first the Updates entry is not listed on the settings page at all, but when updates are pending, then it will appear in the settings page with the expected control for "Always Shown / Disabled / Shown when relevant" EXPECTED RESULT Updates entry should always be listed in the settings window along with it's expected controls, and the controls should determine if the icon shows in the system tray or not.

Yeah, can reproduce. Seems like a general issue with on-demand tray items like Discover Notifier.
i'm also noticing that every time my computer will not wake up from hibernation in the morning -- and i'm forced to power cycle the box -- there are pending updates waiting for me when it reboots. other times when there are no pending updates, it wakes up without issue via the keyboard input.
*** Bug 496915 has been marked as a duplicate of this bug. ***
the failure to wake from sleep when there is a pending update continues to occur (comment 3) and possibly related is while in the process of rebooting for other reasons, when the system comes back up there will be pending updates that were not showing before the reboot... in fact the only time the discover pending updates icon (with the blue dot) ever shows is after a reboot, there have been zero instances of just the blue dot appearing during normal use as would be expected if the icon were always shown.
NotifierItem::setStatusNotifierVisibility() is publishing a new status item on d-bus when pending updates are newly found, and deleting it when there are none left. So, once updates are applied, the status item that should be configurable in the system tray no longer exists anywhere. It should instead publish the status item on d-bus exactly once, keep it there, and toggle its status between Active and Passive when pending updates are present or not. This is a regression. It behaved correctly in Plasma 5. I don't see anything about this that would cause a sleep/wake problem, so I suspect that belongs in a separate bug report.
can confirm the failure to reboot from hibernation was a separate issue (now solved new hardware), and that the expected behavior can be found on plasma 5, which i have since reverted to.
