I've installed Ubuntu 17.10 on the Xiaomi Notebook Ari 13'3 but I couldn't get the fingerprint function running for logon. The Fingerprint GUI sees no device at all. Maybe there are necessary drivers for the Xiaomi Fingerprint sensor?

Here's the output (partial) of lsusb:

Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 004: ID 8087:0a2b Intel Corp.
Bus 001 Device 003: ID 04f3:0c1a Elan Microelectronics Corp.
Bus 001 Device 002: ID 04f2:b5a3 Chicony Electronics Co., Ltd

    Please edit your question to include the output of the lsusb command. This should enumerate the fingerprint reader device, which will help us better troubleshoot your issue.

  • @richbl As a matter of fact, it's not my question, I just have the same problem.

  • The key to what lsusb tells us is that the fingerprint device is from Elan Microelectronics Corp (device 04f3:0c1a). We can use that information to better troubleshoot your issue.

Reset to default

Had the same issue solved by installing fingerprint+gui package. After adding this package Ubuntu recognised the fingerprint HW.

Add ppa source:

sudo apt-add-repository ppa:fingerprint/fingerprint-gui

Update source list: 

sudo apt-get update

Install necessary packages:

sudo apt-get install libbsapi policykit-1-fingerprint-gui fingerprint-gui

Installing this packages will overwrite/remove default package "policykit-gnome" In case you decide to remove this PPA, reinstall default policykit.

    The installation did work, but the interface showed the message "No Devices Found". Did you test it with the device 04f3:0c1a from Elan Microelectronics Corp?
