Title:
Login loop after inactivity in login screen
Status in linux package in Ubuntu:
Fix Released
Bug description:
I have Kubuntu 18.04 installed with /home/$USER directory using
ecryptfs. 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:

If I login as root from virtual terminal and systemctl restart sddm.service
then I'm able to login from anywhere.
