No proper shutdown?

Post by Zweitaktmotor » Sat Aug 10, 2019 11:32 pm

Hi guys, sorry I have run into another problem I need some help with, please:

I have a Dell Optiplex 780 that I boot with LMDE in German from an external USB HD.

From time to time, I found that this installation gets messed up, which presents in some applets in the system tray not being loaded (Mint Update and Weather) and - more importantly - my root password no longer being recognised.

I looked at my ".xsession-errors" file and found a few suspicious entries, among them:
** Message: couldn't access control socket: /run/user/1000/keyring/control: Datei oder Verzeichnis nicht gefunden
(=file not found)

Luckily, I keep disk clones, made with Clonezilla, so that I can revert to a previous state, but I was asking myself what the cause of the problem might be.

I then observed that when I click on Shutdown in Mint Menu, the machine does not properly sign off. It literally cuts the pwer and Bang! the lights go out.

I tried it on a similar machine, a Dell Optiplex 755, with the same results.

I am pretty sure that this behaviour corrupts the hard disk. I remember that LMDE should take quite some time and show a string of messages when shutting down properly. It could be that the error is embedded in one of my clones.

Is there anything that can be done?

Many thanks.
