Introduction

The EgisTec 0570 fingerprint sensor is a popular biometric authentication device used in various laptops, including the Acer Swift 3 (SF314-57). This device has recently gained support in the latest libfprint library, making it possible to use it for fingerprint authentication on Arch Linux. However, some users have reported issues with the fprintd-enroll command not working as expected. In this article, we will explore the possible causes of this issue and provide a step-by-step guide to troubleshoot and resolve the problem.

Hardware and Software Requirements

To use the EgisTec 0570 fingerprint sensor on Arch Linux, you will need the following hardware and software:

Acer Swift 3 (SF314-57) laptop with EgisTec 0570 fingerprint sensor
Arch Linux installed on the laptop
Latest libfprint library installed
fprintd service installed and running

Troubleshooting Steps

If you are experiencing issues with the fprintd-enroll command not working, follow these troubleshooting steps to resolve the problem:

Step 1: Check the libfprint Library

The first step is to check if the latest libfprint library is installed on your system. You can do this by running the following command:

pacman -Q libfprint

If the library is not installed, you can install it using the following command:

sudo pacman -S libfprint

Step 2: Check the fprintd Service

The fprintd service is responsible for managing the fingerprint sensor. You can check if the service is installed and running by running the following command:

sudo systemctl status fprintd

If the service is not running, you can start it using the following command:

sudo systemctl start fprintd

Step 3: Check the Fingerprint Sensor

The next step is to check if the fingerprint sensor is recognized by the system. You can do this by running the following command:

fprintd-enroll -l

This command will list all the fingerprint sensors recognized by the system. If the EgisTec 0570 fingerprint sensor is not listed, you may need to restart the fprintd service or reinstall the libfprint library.

Step 4: Check the Fingerprint Sensor Permissions

The fingerprint sensor requires special permissions to function correctly. You can check if the sensor has the required permissions by running the following command:

fprintd-enroll -p

This command will list the permissions required by the fingerprint sensor. If the sensor does not have the required permissions, you may need to add the necessary permissions using the fprintd-perms command.

Step 5: Check the Fingerprint Sensor Configuration

The final step is to check if the fingerprint sensor is configured correctly. You can do this by running the following command:

fprintd-enroll -c

This command will list the configuration settings for the fingerprint sensor. If the sensor is not configured correctly, you may need to modify the configuration settings using the fprintd-config command.

Conclusion

The EgisTec 0570 fingerprint sensor is a popular biometric authentication device used in various laptops, including the Acer Swift 3 (SF314-57). While support for this device has recently been added to the latest libfprint library, some users have reported issues with the fprintd-enroll command not working as expected. By following the troubleshooting steps outlined in this article, you should be able to resolve the issue and use the fingerprint sensor for biometric authentication on your Arch Linux system.
