A few notes about how I got working fprint in Ubuntu Karmic (since all available HOWTOs treat old versions, other distros or other fingerprint frameworks).

1. Install package libpam-fprint
2. Run the script “pam_fprint_enroll” and follow instructions
3. edit the file /etc/pam.d/common-auth, adding the line

  auth    sufficient                      pam_fprint.so

• before the line

  # here are the per-package modules (the "Primary" block)

That's it: when you reboot, you should be asked to authenticate via the fingerprint reader (and only if it fails via password).

Unfortunately, fingerprint authentication after suspends/screen lock doesn't work (I don't even know if it would with a more advanced configuration).
