Password not accepted after screen lock: "The account is locked due to 3 failed logins". (luks issue?)

I’m running Manjaro 20.1 on the latest 5.8 kernel with Gnome on my Ryzen Thinkpad T14 perfectly fine but i have one strange problem. I’ve set my laptop to lock the screen whenever my display goes blank. But whenever i try to unlock it won’t accept my password and i’m 100% positive that i’m typing it correctly.

I did an install using Architect and i did nothing out of the ordinary except for my partitions. I have the following partitions

  • /boot        FAT32 (unencrypted)
  • /            Volume Group  (/dev/mapper/cryptroot)(luks encrypted)
  •              /dev/mapper/lvg-root          ext4
  •              /dev/mapper/lvg-swap          linuxswap

The encrypted volume group has 2 volumes. 1 ext4 volume for root and 1 volume for swap. I wanted to have a unencrypted boot volume to speed up to boot process. Not sure if this is related to my login problem but i have hunch that it is.

Its PAM not luks. Luks has nothing to dow with authentification at user-session level.
I have the problem as well - i SUSPECT that despite not being in use my fingerprint reader on my T490 does “register” but wrongly and thus if my palm rests on it PAM detects failed logins.

I will go ahead, and because I don’t use it, deactivate the fingerprint reader in the UEFI

Thanks for your reply! I guess i’ll do the same and disable the fingerprint reader since i’m not using it anyway. Hopefully that’ll be the solution.

@Th3Z0ne: I haven’t had the same problem since your solution. I’m not 100% sure if it solved the problem but i’m beginning to think that it did.

I had the same problem. I disabled the fingerprint on the bios and resolved the issue

Not truely a fix for sure - its a work around. The fingerprintreader should not be read if not configured at all. Turning it off in UEFI is more a hack - but it works.
