fingerprint-gui on Linux Mint 19 "Tara" cinnamon works but not on first boot or in software center

On my Lenovo Thinkpad X1 Carbon 3rd. Gen., fingerprint-gui works fine when locking the screen or requesting sudo in terminal. It doesn't work when I freshly boot up the system at first login, and it doesn't work either when installing software from the apt software center over the GUI. Is there a way I can change something so that this works with the fingerprint, too? I must say that I've encrypted LVM partitions running, perhaps this is a reason why it doesn't work at boot time? Attached is my pam-update-auth screen.
