           Summary: Erroneous lock screen invitations to use fingerprint
                    scanner when that is not enabled/configured
    Classification: I don't know
           Product: kde

SUMMARY
My laptop has a fingerprint scanner, but it is likely not detected in Linux.

Initial sign-in does not offer fingerprint sign-in, but coming back from lock
screen does?

I do not see any settings or options to configure fingerprint scanning for lock
screen or authentication.

STEPS TO REPRODUCE
1. on boot, login screen show no indications of fingerprint scanning
functionality
2. in Settings, there is no listed option to configure fingerprint scanning.
3. on screen lock, it offers to use a fingerprint scanner.

OBSERVED RESULT
fingerprint scanner is not detected

EXPECTED RESULT
if there is no fingerprint scanner detected, it shouldn't offer fingerprint
signin.
Ideally I would like to try out the fingerprint scanner on this device though.
