http://packages.qa.debian.org/f/fprintd.html seems to indicate the fprintd exists as a package in Debian. Try installing the fprintd and libpam-fprintd package. > [...] > One more question: I am a bit at a loss regarding Linuxes complete and > utter lack ofbiometrics support.

On the other hand, and YMMV, fingerprint-matching isn't bulletproof, and lots of factors make it rather unreliable -- I needed to scan my finger ~10 times to get it to match in order to log into my laptop. In the end I just gave up and disabled it. Password logins are so much more convenient and reliable, at least with my device. -- Kind regards, Loong Jin -- Kind regards, Loong Jin
