disable packagekitd auto start in KDE

lately, updated to OpenSUSE Leap 42.1 from 13.2. but i couldnt disable the ‘packagekitd’ service.

And it is always annoying, boring, blah blah…

anyway, I HATE IT!!

HERE IS THE SOLUTION:

1. Right click on ‘System Tray’;
2. Select ‘System Tray Settings’;
3. You should see an item( in ‘Extra Items’ section) named ‘Software Updates’.
4. Uncheck the box, then apply the change.

That’s all, so simple. lol.
