Hi, I am trying to get the 0a5c:5834 working in arch linux.

What exactly does this line do? LIBFPRINT_VERSION=$(dpkg -l | grep libfprint | awk '{print $3}' | cut -d ':' -f 2 | cut -d '-' -f 1)

Is there a specific branch? My idea was just to install the latest git version through AUR: https://archlinux.org/packages/extra/x86_64/libfprint/ (which it doesnt work by the way) :)

Hi, I am trying to get the 0a5c:5834 working in arch linux.

This gist is for debian testing

What exactly does this line do? LIBFPRINT_VERSION=$(dpkg -l | grep libfprint | awk '{print $3}' | cut -d ':' -f 2 | cut -d '-' -f 1)

Gets the currently installed version of libfrint via dpkg

Is there a specific branch?

for libfprint? Yes, the tag that points at the tod version of the currently installed version of libfprint

Ok on debian testing but

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

was necessary for me

What exactly does this line do? LIBFPRINT_VERSION=$(dpkg -l | grep libfprint | awk '{print $3}' | cut -d ':' -f 2 | cut -d '-' -f 1)

It was returning some garbase versions for me, had to skip/define this var manually with 1.94.2

20080303git
1.94.2
0.8.2

LIBFPRINT_VERSION=$(dpkg -l | grep libfprint | awk '{print $3}' | cut -d ':' -f 2 | cut -d '-' -f 1)

@vin-c mind sending me the output of that command?
Changed to a different way to get the version - mind testing that and letting me know if it works better or it's still not good?

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

not sure why. will double-check. Thanks for the report Indeed, my system had that file there as a leftover from a previous build. Fixed.

Update 05.10.2022

• Manually install libssl1.1 from the Debian Sid repository, as the binary blob is compiled against it
• Fix path of the systemd override file

The filenames for the libssl package doesn't match on lines 50-51

@johan-osvaldsson-ingka thanks, fixed.

Ubuntu 22.11
Dell Latitude 3790 2-in-1

When running in Ubuntu, DEBIAN_FRONTEND=noninteractive throws an error and I just removed them.
With a relatively fresh install of 22.11, the apt build-dep command on line 9 was failing with "E: You must put some 'deb-src' URIs in your sources.list"
Resolution:

sudo cp /etc/apt/sources.list /etc/apt/sources.list~
sudo sed -Ei 's/^# deb-src /deb-src /' /etc/apt/sources.list
sudo apt update

I would imagine that there would be some way to correct for this issue by detecting the error or looking at /etc/apt/sources.list.

Anyway, at the end of the day lsusb can see my scanner but I cannot connect it to fprintd...

@iconoclasthero this script is for debian only.

Ubuntu users should use the built-in driver (dsd/fprintd#3 (comment)), eventually using the "staging" PPA (https://launchpad.net/~andch/+archive/ubuntu/staging-fprint) but keep in mind that the latest release has an issue and a file needs to be manually edited to make it work (read https://bugs.launchpad.net/libfprint-2-tod1-broadcom/+bug/1991794 carefully)

As soon as it comes back online I can try to install and then address the fix in comment 21...

Update 15.11.2022

• Use a newer version of the library, compiled against libssl3, and with a newer firmware

@vin-c @johan-osvaldsson-ingka mind giving it a spin?

@giannello I just got around to trying it, and it works as expected! I'm running bookworm/sid Debian 6.1.11-1 and kernel 6.1.0-4-amd64

It did work for me also, except after suspend as reported by others. It required a reboot to get it functioning again...

However with the newest version that I used from the upstream branch:
git clone -b upstream https://git.launchpad.net/libfprint-2-tod1-broadcom
it works flawlessly even after suspend.

Also there is no need for the fix for the wrong firmware version anymore...

Unfortunately, fprintd package has been removed from testing since August, though libfprint-2-2 is still there. I had to add stable repo to sources to install fprintd.

Branch jammy should be used while cloning the closed source binaries to get the ones compiled against libssl3.

build-dep package doesn't exist now, so install the following (extracted from meson.build):

meson gtk-doc-tools libgudev-1.0-dev libnss3-dev libgusb-dev libpixman-1-dev libglib2.0-dev libgirepository1.0-dev libcairo2-dev

I used libfprint version (as it is > fprintd ver on testing) in Line 42 with the following command:

dpkg-query --showformat='${Version}' --show libfprint-2-2 | cut -d '-' -f 1 | cut -d ":" -f 2

Line 46 of this gist should be removed else cannot build (gives installed_tests variable failure).

The last echos are also useless now.

(Made these changes in forked gist here, please update this gist.)

---

After all this, I can enroll using fprintd-enroll and verify using fprintd-verify.

But GDM cannot allow me to login, it has continuous failures and is stuck in a loop so cannot login. Does anyone know a fix for this?

Fixed, installing from sid

That's not a package, it's an apt command. Anyway, fixed by pointing at libfprint-2-2 as it exists in the testing repo

Fixed, we can exclude the examples from this build

Any log/error you can share?

I somehow missed/dropped libpam-fprintd package somewhere in the process (as the library isn't there in testing either).

After installing it, GDM works fine. Sorry for the noise, and thanks for everything! It works nicely and fast!

Hi @giannello Many thanks for this script! I thought I would never get my laptop fingerprint sensor to work in Debian! I was able to register the fingerprints and was able to unlock screen and sudo auths. The setup works in the Debian 12 stable but it's wonky. After reboot, it breaks manytimes randomly. The login screen takes a while to appear(or never forcing to reboot again) and same for the sudo commands. Eventhough we pass the --no-timeout to the binary, it still exits. Trying to run fprintd from console is exiting with some C errors. Shutdown takes a lot of time and I had to press power button to turn off the laptop. When turning on the laptop, I have to reboot 2/3 times for the login screen to appear.

I'm facing this issue now everytime there is a fingerprint auth

sudo[3353]: pam_fprintd(sudo:auth): GetDevices failed: Connection timed out

From Systemd, I saw some errors:
