I'm trying to use the fingerprint sensor of my HP Envy 04f3:0c4c Elan Microelectronics Corp. It seems to be supported in a branch of fprint:

If you have a 04f3:0c4c or a 04f3:0c00 use the experimental package libfprint-elanmoc2-newdrvs-gitAUR from libfprint-elanmoc2-newdrvs waiting to be merged into libfprint-elanmoc2 which is also waiting to be merged into the main libfprint.

https://wiki.archlinux.org/title/Fprint

I successfully compiled the driver...and now it's sitting in the build dir and I don't know how to add it to my Ubuntu 22.04. Can someone point me to the next step? Thanks!

I have a Lenovo that has the same fingerprint reader built into the power button. The following link is the method I have shared on this forum that it working for my laptop.

https://askubuntu.com/a/1488580/1737945

How to enable 0c4b ELAN FingerPrint Driver for Ubuntu 22.04 64bit. A common fingerprint reader on Lenovo laptops.

Confirm the device in a terminal.

$ lsusb |grep Elan
Bus 003 Device 002: ID 04f3:0c4b Elan Microelectronics Corp. ELAN:Fingerprint

or

$ hwinfo | grep Fingerprint
Device: usb 0x0c4b "ELAN:Fingerprint"

After confirming your device is the 0c4b, download the drive from the Lenovo support site.

Google search: "ELAN FingerPrint Driver for Ubuntu 22.04 - ThinkPad E14 Gen ..."

or

use the following link: https://support.lenovo.com/us/en/downloads/ds560939-elan-fingerprint-driver-for-ubuntu-2204-thinkpad-e14-gen-4-e15-gen-4

Download the driver "ELAN FingerPrint Driver r1slf01w.zip"

The site will ask for a serial number on the first try, ignore this by clicking cancel on the pop-up screen & click download again. On the second try it will download the zip file without the popup asking for a serial number.

Extract the zip file & open a terminal in the extracted folder. The only contents of the folder should be "libfprint-2-tod1-elan.so".

In the terminal:

(Assumed location of download, may be different on your system)

$ cd ~/Download/r1slf01w/libfprint-2-tod1-elan_0.0.8_Ubuntu22.04

(best practice before any new install of applications)

$ sudo apt-get update && sudo apt-get upgrade

(This installs the fprint library & ssl tools. Note that libssl3 should already be installed on Ubuntu 22.04 fresh install, so may be no need to install libssl3)

$ sudo apt install libfprint-2-tod1 libssl3

(Create a directory for the system to access the driver)

$ sudo mkdir -p /usr/lib/x86_64-linux-gnu/libfprint-2/tod-1/

(Copy the driver into the new folder)

$ sudo cp libfprint-2-tod1-elan.so /usr/lib/x86_64-linux-gnu/libfprint-2/tod-1/

(Restart the fprint service to load the new driver)

$ sudo systemctl restart fprintd.service

(Exit the terminal)

$ exit

Go to settings, select "Users" & enable "fingerprint login". Click the marker to the right of "Enabled" & Enroll fingerprints.
