What doesn't work out-of-the-box

Fingerprint Sensor: LighTuning Technology Inc. ETU906Axx-E (1c7a:05b1)

Bus 003 Device 003: ID 1c7a:05b1 LighTuning Technology Inc. ETU906Axx-E

• Requires a patched libfprint.
  • Patched build (COPR): https://copr.fedorainfracloud.org/coprs/likeablob/libfprint-fmv-etu906axx-e/

# Enable this copr repository
sudo dnf copr enable likeablob/libfprint-fmv-etu906axx-e

# Override libfprint package
sudo rpm-ostree override replace \
  --experimental \
  --from repo=copr:copr.fedorainfracloud.org:likeablob:libfprint-fmv-etu906axx-e \
  libfprint

# Reboot to apply changes
systemctl reboot
