GNOME/GDM Fingerprint Feedback Deployment

This repository provides a team-friendly deployment path for faster visible fingerprint failure feedback on Fedora systems using authselect.

Files

tools/gnome_fprint_feedback_setup.sh
tools/gnome_fprint_feedback_rollback.sh

Apply

Default (recommended):

cd /path/to/Fedora_Fingerprint_Feedback
sudo ./tools/gnome_fprint_feedback_setup.sh

Custom tuning:

sudo ./tools/gnome_fprint_feedback_setup.sh --max-tries 2 --timeout 6

Validate

authselect current --raw
authselect check
grep pam_fprintd /etc/authselect/custom/local-fprint-feedback/fingerprint-auth
grep pam_fprintd /etc/pam.d/fingerprint-auth

Expected effective line:

pam_fprintd.so max-tries=2 timeout=6

Rollback

Restore previous authselect selection saved during setup:

cd /path/to/Fedora_Fingerprint_Feedback
sudo ./tools/gnome_fprint_feedback_rollback.sh

Rollback and remove custom profile directory:

sudo ./tools/gnome_fprint_feedback_rollback.sh --remove-profile

Notes

Scripts must be run as root.
Setup stores previous authselect current --raw in:
- /etc/authselect/custom/local-fprint-feedback/.previous-authselect-raw
If no saved state exists, rollback falls back to:
- local with-fingerprint with-silent-lastlog with-mdns4
