Install fingerprint identification on ThinkPad X220 Ubuntu 14.10
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:
[Html] view plaincopyprint? View the CODE piece derived from my CODE piece on the CODE # sudo pam-auth-update
# Sudo pam-auth-update and 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.
