Title:
fprintd fails often and there are traces in log files
Status in fprintd package in Ubuntu:
Fix Released
Bug description:
After installation of fprintd, pam module and related middleware, and
enrolling fingerprint, it started to work within expected pattern in
command-line interface cases - in most cases it is enough one scan,
sometimes needs second scan and rarely third or even defaulting to
password.
When it comes to login into Mate desktop environment (I use Mate on
Ubuntu standard distribution), it has significantly worse misses rate
- password typed in approximately 60-70% cases.
This is snippet from syslog (hostname changed to host)
