Lenovo X1 Yoga 2nd (138a:0097) + Fedora = various problems

[FlyinPancake]

Hi all, I have tried installing the driver but I couldn't get it to work. What would be the correct procedure (I followed the instructions on from the README) ?

I'll provide the logs that are needed, I just don't know where to begin.

Hello, I too am having issues with Fedora 35 and a Lenovo ThinkPad T470 with a 138a:0097 Validity Sensor fingerprint device.I have gotten this to python-validity package to work with the same ThinkPad T470 running Ubuntu 21.10 so I am no sure what is wrong.

In Fedora 35; I run: $ sudo dnf copr enable tigro/python-validity Then: $ sudo dnf install open-fprintd fprintd-clients fprintd-clients-pam python3-validity

It shows everything is installed, and complete. And upon running fprintd-enroll, I get this; Impossible to enroll: GDBus.Error:net.reactivated.Fprint.Error.NoSuchDevice:

What is going on and can anyone point me and the original poster to a fix? Like I said, I have had this package working in Ubuntu 21.10 with the same laptop but with Fedora I run into this error.

I have made some progress into this issue and it seems to be that some files are missing and ownership settings are incorrect. I got fprintd to enroll my finger print with the following:

sudo touch /usr/share/python-validity/backoff
sudo touch /usr/share/python-validity/calib-data.bin

Then:

cd /usr/share/python-validity/ && ls -la
sudo chmod 755 6_07f_lenovo_mis_qm.xpfwext

After this, I restarted the python-3-validity services in systemctl; rebooted my system and was able to enroll my index finger with fprintd-enroll and it is verified! Now, at this point however, to get this to work with Gnome do the following:

$ sudo authselect current
$ sudo authselect enable-feature with-fingerprint
$ sudo authselect apply-changes

Hi Guys,

I ran into the very same issue on a Yoga 370. The above described solution works perfectly, thanks a lot.

I've tested this on both latest Manjaro and Pop! 20.04 as well as on Pop! 21.10 and I did not experience any issues there.

[FlyinPancake]

Well I tried the solution provided by @kambiz. When I try to fprintd-enroll i get the following

➜ fprintd-enroll
Using device /net/reactivated/Fprint/Device/4
Enrolling right-index-finger finger.
Enroll result: enroll-stage-passed
Enroll result: enroll-failed
EnrollStop failed: GDBus.Error:org.freedesktop.DBus.Error.NoReply: Remote peer disconnected

The error occures when I lift my finger up from the fingerprint sensor.

I've tried with a clean install of fedora and still no success

I tried the solution @kambiz gave. After using systemctl restart python3-validity.service to restart the service before using fprintd-enroll, everything appeared to work. In my case, I also had to use systemctl enable to make it work at startup.

Thank you!

Update from my part: I have discovered my fingerprint reader somehow kicked the bucket, as using it under Windows wasn't possible.

I have moved on from that computer and I can confirm that the T14 Gen2 has great fingerprint reader compatibility ootb.

I had the same problem with Fedora 38 running on Thinkpad X1 Carbon 3rd Gen. Also, the existing copr repo does not work any more due to changed Python ABI and some other changes.

I forked @Tigro's copr, fixed it up and rebuilt for Fedora 38: https://copr.fedorainfracloud.org/coprs/pbo/python-validity/

To enable it:

$ sudo dnf copr enable pbo/python-validity

All other instructions are the same. After applying manual fix by @kambiz https://github.com/uunicorn/python-validity/issues/103#issuecomment-966016605 the sensor now works correctly.

sudo touch /usr/share/python-validity/backoff
sudo touch /usr/share/python-validity/calib-data.bin

Then:

cd /usr/share/python-validity/ && ls -la
sudo chmod 755 6_07f_lenovo_mis_qm.xpfwext

After this, I restarted the python-3-validity services in systemctl; rebooted my system and was able to enroll my index finger with fprintd-enroll and it is verified! (…)

Hi, dreamer

Can you send me patch, and I will rebuild packages?

[dreamer]

@Tigro Here you go, thanks for maintaining the copr repo!

Patch to .spec file: fprintd-clients-spec.patch.txt (GitHub does not allow upload of .path files :roll_eyes:) - this change fixes build for F38, it probably won't work for F37, it definitely does not for RHEL9 (tried yesterday).

Or you can just grab my .src.rpm from copr build: link.

Builds of open-fprintd and python-validity didn't need any changes in .spec file - I just resubmitted your .src.rpm file.

I think we need to revise the patches included in these rpm packages and try to upstream them…

[Tigro]

@dreamer thank you for you patch. I have rebuilt all packages for Fedora 38 and Rawhide. In my case no dependencies problems dnf --releasever 38 --nogpgcheck distro-sync.
