As a display manager I use standard sddm and sddm-locker. If I leave my PC for a weekend powered on and locked then I'm unable to log in on monday. When I enter correct password in sddm - it prints that I entered incorrect password. If I switch to any virtual terminal and try to login there I'm immediately thrown out of session back to login prompt. That's what I see in logs: auth.log: Jun 18 12:59:55 yanPC login[14123]: pam_ecryptfs: Passphrase file wrapped Jun 18 12:59:56 yanPC login[14031]: pam_unix(login:session): session opened for user yan by LOGIN(uid=0) Jun 18 12:59:56 yanPC systemd-logind[770]: New session 1757 of user yan.
