KDE and other things reseted

Everything was okey, then i shut off my computer and disconnected the cables (Mouse, keyboard, wland stick, monitor (hdmi, displayport) etc, to clean it. After it i tarted my PC and i noticed my taskbar configuration was gone and the Wallpaper was the standart again.. Then i started my usual programs (discord, vpn, browser) and in every program i was suddenly logged out here in this forum too, i suddenly wasnt logged in anymore. When i tried rebooting into a snapshot, i was greeted with this error message: "Configuration file /var/lib/sddm/.config/sddm-greeterrc not writable"
And my Keyring was reseted too. I was asked to create a key from that KDE wallet thing.

You can disregard that message. You should still be able to login and restore the snapshot.

That being said, I don't think restoring a root snapshot will help at this point because everything you are talking about is actually part of your /home which isn't part of the root snapshot.

Well, but why did that happen?

If by "that" you are referring to that message on snapshot boot, it is because the snapshot is read-only.

If by "that" you mean your configuration being different, I am not sure. It is hard to know without looking at the state of your home directory.

Is there a simple command or something to show the things you need to know from my home directory?

Not really, I would start by making sure everything has the correct permissions including ownership.

Most like due to cleaning your computer you may have caused a static electrical during your "cleaning". Especially of you failed to correctly clean and reconnect everything by following procedure
