I’ve recently enrolled fingerprints on my laptop (Framework 13) and all seems to work perfectly, on the hardware side (finger recognition, verification, etc).
I want to use that only to unlock the screen, not for login.
It seems that KDE Plasma does a good job there, having everything already setup. I just needed to install fprintd and enroll the fingers.
Now, I can-t really figure out why but it seems that unlocking the screen works, but only if I lock it manually (e.g. with Super+L) and don’t wait for the display to turn black.
I’m not super sure about how to exactly reproduce this, but it seems that whenever the laptop lock automatically, e.g. due to inactivity, or if I wait too long after locking the screen (like a few tens of minutes maybe), then SDDM only prompts for a password, there is no instruction under the password prompt for a fingerprint, and touching the fingerprint reader has no effect.
Anyone the same? Could it be something weird with my setup?
BTW, details of my laptop:
