KDE - The screen locker is broken

Hello!
Sorry for my bad english sad
I have a problem with screen locker in Kde and I can not get over it

Error Message:

The screen locker is broken and unlocking is not possible anymore.
In order to unlock switch to a virtual terminal (e.g. Ctrl+Alt+F2),
log in and execute the command:
loginctl unlock session c2
Afterwards switch back to the running session

Re: KDE - The screen locker is broken

This behaviour usually shows up after you update your system (some combination of plasma, systemd and/or dbus packages). Have you just updated your system?

Not today but this error appears already from 3 updates.
You can direct me to the logs to see?

Trying to do a better analysis, I think this problem was born with the addition of a second monitor connected to the thunderbolt port (first is connected in hdmi port)  and the addition of a usb hub with port vga + hdmi + ethernet (ecc. ecc.)
From some research I arrived at this document:
http://www.lightofdawn.org/wiki/wiki.cgi/LinuxMultiSeat

My list seats is this:

loginctl list-seats
SEAT 
seat0

1 seats listed.

but I think at one point I got lost hahahahaha

Re: KDE - The screen locker is broken

What do you use as wallpaper type for the locker? World Map?

Re: KDE - The screen locker is broken

You don't have more than one seat (or at least, you haven't configured more than one seat), so multiseat is not related to your issue.

You can check the logs with journalctl: https://wiki.archlinux.org/index.php/Sy … ing_output

Possible points of interest would be the journal for systemd-logind, as well as the user journal for your account (although plasma is a very.. chatty DE, you will get a lot of unrelated log spam, start by looking at -p3 and higher messages).

Re: KDE - The screen locker is broken

To be sure: not the wallpaper on your desktop by the fancyness of your screenlocker.

stat /sbin/unix_chkpwd
LC_ALL=C pacman -Qkk | grep -v ', 0 altered files'
