Configuration problem Linux Mint KDE
 

Hello!

I've recently installed Linux Mint KDE and I'm having the following problem: everytime I shutdown/restart the system in a 'wrong way' (with the power button) or the computer runs out of battery, Linux Mint resets some configurations.
Some things that get reset are:
- Some windows configurations (Thunderbird usually starts in the Desktop #2, but when this happens it starts at the default desktop, #1). - It forgets the rules of the windows
- Task bar / panel. The icons I have chosen disappear and some configurations restart (like the order of the windows or their grouping)
- Wallpapers. They turn in the default Linux Mint KDE wallpaper.
- Favourites in the kickoff launcher
- I have to write again some wifi passwords
- I have to write again some mail passwords for thunderbird
- I have to create a new password in KDE Wallet
- It forgets some shortcuts, like the one I have for KRunner...

It doesn't change other type of configurations, like the appearance of the windows, language, the options of the corners, etc.

What could I do?
Of course, the first thing I should do is not to restart/shutdown in a wrong way, but in the case it happens...

Thanks! (and sorry for my English)

Linux Mint 17.3
Linux 3.19.0-32-generic
KDE 4.13.2

What happens if you don't shutdown "the wrong way"?
Are you 100% certain you are not booting off the installation media to a LiveCD environment?

Everything remains 'as I said'. It happens what should happen in a normal computer, that If I said (for example) that certain picture must be my wallpaper, it will keep being my wallpaper until I said other thing.

Yes, absolutely sure ;). My documents, the configuration of (for example) Firefox or other apps and many other things behave normally.

Thanks anyway!

I am not a KDE "guy" so I don't know how to assist you any further. Sorry about that.

Someone could help, please?

Erm, if you cut the power to any running OS you will have problems -- the configuration of your desktop being the least of it.
What do you think should happen? You could try things like running synch to make sure things are written to disk rather than being cached after every change but before you explain how you expect a running OS not to be messed up, at least in some way, by a power cut you would need to elaborate.

The kde battery monitor widget (or whatever its called) has settings to alert you when the battery charge is low. This would be a good time to either plug in power or shutdown the computer. Try to be careful about it, I guess.

Thanks.
You're right, of course, but these things happen. For me It's too risky to lose my wifi passwords or my configurations just because one time I forgot to shutdown the computer properly...
Trust me If I say that I cannot control every situation related with the power management of my computer, due to external and personal matters. It was like this for years and I had never experienced problems if, by chance, my computer turned off incorrectly.

273, what do you mean by 'running synch'?

Thanks again

sync': Synchronize data on disk with memory

I refer you to the above post for clarification of my last point.

If you are worried about access to the physical machine then just run from a live CD or USB and all data will be in RAM giving aless than 5 minutes for somebody to take data from a system whose power is cut.
