ThinkPad T480 fingerprint reader on Fedora Linux

Background

The Synaptics fingerprint sensor (06cb:009a) present on my T480 is not supported by libfprint and fprintd as it requires a non-free binary blob. uunicorn created open-fprintd, a replacement for fprintd, that allows for loading of binary blobs. In conjunction with their python-validity driver we are able to make use of the inbuilt fingerprint reader. The following instructions were tested against Fedora Linux 35.

Installing open-fprintd and python-validity

sudo dnf copr enable tigro/python-validity
sudo dnf install open-fprintd fprintd-clients fprintd-clients-pam python3-validity

An Example of Play

To further clarify what really goes on during an AD&D game, read the following example. This is typical of the sort of action that occurs during a playing session. Shortly before this example begins, three player characters fought a skirmish with a wererat (a creature similar to a werewolf but which becomes an enormous rat instead of a wolf). The wererat was wounded and fled down a tunnel. The characters are in pursuit. The group includes two fighters and a cleric.

Fighter 1 is the group's leader.
