Fingerprint reader

The fingerprint reader works with some recent firmware and software updates.

  1. Use fwupd to install the latest firmware for "Synaptics Prometheus Fingerprint Reader". The update might have to be done manually as the released firmware is in testing; or you could enable the testing remote in fwupd to allow automated upgrade. The relevant firmwares are Prometheus Fingerprint Reader and Prometheus Fingerprint Reader Configuration.
  2. fprintd ≥ 1.90.1 and libfprint ≥ 1.90.1 are required.

fprint has more details on how to setup the fingerprint, for PAM-based authentication for example.


Backlight works correctly by manipulating the values, between 0-255, inside /sys/class/backlight/amdgpu_bl0/brightness or using a backlight managing utility.

systemd-backlight@backlight:acpi_video0.service requires masking as it seems to be triggered and fails on boot.


Although the fwupd utility works to update some of the components, Lenovo does not support BIOS updates for the T495s yet. A BIOS update Bootable CD iso that is OS agnostic may be downloaded from Lenovo support[1].
