Fingerprint Reader Setup on Linux - Synaptics Sensors

Complete guide for configuring Synaptics fingerprint readers (including Metallica MIS Touch) on Linux distributions using python-validity and fprintd.

Device Compatibility

This guide specifically covers Synaptics fingerprint sensors that require proprietary drivers:

Synaptics Metallica MIS Touch (06cb:009a)
Synaptics Prometheus (06cb:0081)

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

Install NixOS with BTRFS and IN-RAM root

1. Format and partition the hard drive

Create the GPT partition table
- $ parted /dev/sdX mklabel gpt
Create the UEFI FAT32 partition (which will be /dev/sdXY)
- $ parted /dev/sdX mkpart esp fat32 1MiB 512MiB
- $ parted /dev/sdX set 1 esp on
- $ parted /dev/sdX set 1 boot on

$ mkfs.fat -F 32 -n UEFI /dev/sdXY

Workarounds for Netflix and the blocking of Hurricane Electric IPv6 tunnels

The dreaded "You seem to be using an unblocker or proxy." error message. Cool story bro.

This gist was essentially created out of my own rant about Netflix being hostile to IPv6 tunnel services since June 2016. You are welcome to read my opinion on the matter, this is the more technical side to the issue and how to combat it within your own network.

Since I wrote this, various GitHub users have contributed their thoughts and ideas which has been incorporated into this gist. Thank you to everyone who have contributed their own methods and implementations.

The problem

Netflix now treats IPv6 tunnel brokers (such as Hurricane Electric) as proxy servers. A while ago it became apparent to users and Netflix that somewhat by accident, IPv6 tunnel users were being served content outside of their geolocation because of the way Netflix was identifyi
