Install fingerprint identification on X220/T530Ubuntu14.10/LinuxMint17.1

On Ubuntu, you can install fprint-demo and fingerprint-gui as the fingerprint recognition software for ThinkPad.

I tried fprint-demo, which can be used with the Ubuntu SYSTEM account, but the recognition effect is poor.

Fingerprint-gui runs as an independent fingerprint software, and the recognition effect is good. Therefore, fingerprint-gui is used.

Install Ubuntu 14.10

1. Add PPA

# Sudo add-apt-repository ppa: fingerprint/fingerprint-gui # sudo apt-get update

2. Installation

Sudo apt-get install fingerprint-guis policykit-1-fingerprint-gui libbsapi

Among them, libbsapi is designed for UPEK chip installation

3. Run the fingerprint-gui program, input the fingerprint, and log out.

4. Possible Problems
If the configuration does not take effect after you follow these steps, you can try to run:

# Sudo pam-auth-update

Then confirm that the PAM Configuration File "Fingerprint authentication by FingerprintGUI" comes first in the list and is enabled. If not, try to run:

Sudo pam-auth-update-force

If you have any questions, check the Installation log:/var/log/auth. log to find the cause.
