Description Ray Leon 2023-05-15 15:01:00 UTC 
SUMMARY
I've recently set up fingerprint authentication with the KDE lock screen, but I still need to get to the password entry screen by moving the mouse before fingerprint authentication starts working. It'd be nice if I could just press on the fingerprint reader in order to unlock the screen.

STEPS TO REPRODUCE
1. Set up fprintd and add 'auth sufficient pam_fprintd.so' to /etc/pam.d/kde
2. Lock the screen
3. Try to use the fingerprint reader without using the mouse

OBSERVED RESULT
Screen should unlock if fingerprint matches

EXPECTED RESULT
I have to disturb the screen somehow before I can unlock it.

Yes, this periodically breaks, unfortunately.
Comment 2 Ray Leon 2023-05-23 13:58:30 UTC 
It seems like unlimited timeouts / timeouts greater than 99 seconds are currently broken in pam_fprintd (https://gitlab.freedesktop.org/libfprint/fprintd/-/issues/147), so this might not be fixable at the moment.

Hello,

The fprintd issue mentioned by Ray still doesn't seem to be solved. I don;lt image there is any workaround on the plasma side?

Hello! Seems like a PR has been merged to fix the linked fprintd issue a while ago. Could this be looked into again? Thanks!
Comment 8 Nate Graham 2025-09-16 20:45:44 UTC 
I'm afraid this hasn't been implemented yet.
