KDE auto changing wallpaper and removing widget

Support KDE Plasma
1

Hello,

Is there any know issue related to KDE Plama or Manjaro that is automatic changing desktop set up?

It’s a second time this weak, and just after the latest Stable update (19/nov/2021), I shut down my PC without any issue but when I do log on everything related to the desktop is changed, the wallpaper back to default one, the icon sizes back to default one, preview checkbox is marked, files in the the desktop are auto arranged in the grid and all my widget are gone. Very strange.

Below an image as I set up again

Unfortunately with Plasma this does happen every once in awhile. From what I’ve seen there really is no rhyme or reason to what causes it.

Not really…
I havent seen it happen to me once.
Though, I did recently help someone who eventually admitted they were attempting to use a wallpaper from a windoze partition that was not auto-mounted (thus why they lost their wallpaper every reboot).

Do you guys know the command line to clear KDE Plasma cache? I could try that way.

Then you got lucky. Like I said it’s rare but does happen.

I really think luck has little to do with it. Over years and multiple machines. But I hesitate to make this post for the way it sounds … ehhhh … please see the link above - “configuration related” …

So I followed the procedure below.

Fortunately today when I logged in my desktop was as it should be.

Clean cache to resolve upgrade problems

The problem may be caused by old cache. Sometimes, after an upgrade, the old cache might introduce strange, hard to debug behaviour such as unkillable shells, hangs when changing various settings, Ark being unable to extract archives or Amarok not recognizing any of your music. This solution can also resolve problems with KDE and Qt applications looking bad after an update.

Rebuild the cache using the following commands:

$ rm ~/.config/Trolltech.conf
$ kbuildsycoca5 --noincremental

Lets see if don’t face the issue anymore.

Thank you for the support.
