Bug 389297

A short addition: the "extra items" list in system tray settings is empty.

It's not a design change; extra items should be populated.

I have not seen any other reports of this so it's quite unusual.
If you run plasmashell manually from konsole is there anything relevant in the output.

Do you have this issue if you create a new user and log in?

Screenshot. Settings get stucked in this view.

Yes, the same happens for a new user. Even more: I cannot change anything in system tray settings. I get stuck with the window attached above and with the message:

"Layout changes must be applied before other changes can be made."

I cannot switch to other menu entries nor does anything happen by pressing "Apply".

Maybe this is a hint about what is going wrong here.

Here the same behavior is described:

https://forums.opensuse.org/showthread.php/529253-Configure-Desktop-seems-not-to-work-now

So at least I am not the only one and it is a wider issue than just system tray.

I still have problems with 5.12 version.

When i start systemsettings5 from console and go to layout, I get the following errors:

I still cannot add new panels or change the wallpaper. The 'Extra Items' in the system tray are additional but not the main problem I think.

I have this problem with KDE Nedon with Plasma 5.12.
I can't change the wallpaper.

More info. When I put the command "systemsettings5" appears these lines:

KActivities: Database connection:  "kactivities_db_resources_140557141772480_readonly"

Update to Plasma 5.12.2 and the problem still exist.

What do you mean you can't change wallpaper? Are there no options? Or it fails to apply? Can I have a screenshot maybe?

Can I see command line output of plasmshell (system settings isn't very relevnat here)

Do you have a kpluginindex.json file in /usr/share/plasma/wallpapers/?

Yes, I have it.

(In reply to Baltasar from comment #14)
> Yes, I have it.

Then that's your problem, delete it. You've probably run Plasma as root at some point.

It works!!!!
Thank you!!!!

Antonio, wow, wouldn't have thought of that.

@Stas can you confirm the same thing

For me the file was in /usr/share/plasma/plasmoids/kpluginindex.json
And yes, deleting it solved the problem.

Thanks for the solution.

Hello,
after an update (plasma desktop packages to 5.13.4 yesterday) on a debian stretch, problems came:
- system is gone:not networkmanager, no volume control, no notifications, etc..
- no right-click: on desktop only (app ok)
- krunner don't lets me run cmd like kquit/ksqtart
- shortcut  disable: alt+f1 & cannot reasigne on
- about nm, i'm constraint to activate network throug system-settings


 to resolve this problem i rm all kpluginindex.json's files 
but nothing

Since I have not found the right place for a question about system tray as such, maybe someone here knows the answer: is it a bug & how to fix it ?

thanks

The messages of the users are systematically ignored and negated.
It seems only the will of the developers counts.
Because not what the users need is implemented, but what the developer wants to try.
At the moment you can only say: KDE is dead because it is not usable.
Let's see if it becomes usable again, or finally disappears into insignificance.
