Ubuntu 12.04 Fingerprint Reader

Fingerprint reader worked when signing in, but the screenlock unlock doesn’t seem to use the reader. After resuming from suspend at log-in screen, it didn’t work. I’ve been using Thinkfinger but it hasn’t been updated since 2007.

First I found a reference in askubuntu.com that questioned the age of Thinkfinger and recommended Fingerprint GUI.

I still have Thinkfinger installed. The first step was to disable it in /etc/pam.d/common-auth by commenting out the pam_thinkfinger.so line. Next I followed the instructions to install Fingerprint GUI. It was pretty simple.

To clean up, I removed the packages libpam-thinkfinger, libthinkfinger0 and thinkfinger-tools.
