FingerPrint Authentication

guiodic · 1 May 2022 09:09

Hello everyone, I was assisting the user on reddit. I continue here.

We had arrived at the firmware installation.

Have you tried installing python-spidev from aur and trying to flash the firmware again?

guiodic · 1 May 2022 09:20

to install python-spidev from aur:

paru -S python-spidev

LM10 · 1 May 2022 12:19

wish it was that easy, My device is not in the list.

LM10 · 1 May 2022 12:23

yes when i run sudo python3 run_538d.py i get:-
Traceback (most recent call last):

In my case the ID (04f3:0c4b) is listed as Supported & Unsupported , but clearly it is Unsupported as fprintd-enroll throws an error.

So you might like to check the unsupported list too in case it reveals any extra info.

guiodic · 1 May 2022 16:51

so install
paru -S python-periphery

and try again

thanks after that it worked now when i run
paru -S frintd libfprint-goodix-521d
it throws:-
:: Resolving dependencies…
error: could not find all required packages:
frintd (target)

guiodic · 3 May 2022 08:44

mispelled: printd

paru -S fprintd libfprint-goodix-521d

once installed fprintd and libfprint-goodix-521d you should reboot and the try to enroll a fingerprint.

fprintd-enroll

if it works the finger is registered.

Open the [Activities] overview and start typing Users.

Click on Users to open the panel.

Press on Disabled, next to Fingerprint Login to add a fingerprint for the selected account.

Select the finger that you want to use for the fingerprint, then Next.

Follow the instructions in the dialog and swipe your finger at a moderate speed over your fingerprint reader. Once the computer has a good record of your fingerprint, you will see a Done! message.

Select Next. You will see a confirmation message that your fingerprint was saved successfully. Select Close to finish.

Check that your fingerprint works

Now check that your new fingerprint login works. If you register a fingerprint, you still have the option to log in with your password.

Save any open work, and then [log out]

At the login screen, select your name from the list. The password entry form will appear.

Instead of typing your password, you should be able to swipe your finger on the fingerprint reader.

Impossible to enroll: GDBus.Error:net.reactivated.Fprint.Error.NoSuchDevice: No devices available
this is the output i get when i run fprintd-enroll

guiodic · 5 May 2022 09:39

did you installed the driver? try again

paru -S fprintd libfprint-goodix-521d

btw if you rebooted on windows you must flash again the sensor

LM10 · 5 May 2022 13:17

yes, i did install the driver.
I haven’t even installed windows.

LM10 · 5 May 2022 13:20

BTW you know that my device is not in the list of supported devices:-
https://fprint.freedesktop.org/supported-devices.html

guiodic · 5 May 2022 13:30

yes i know.

It’s my device too.

lsusb | grep "Goodix"                                                                                                                                        
                                                                                                                                                                       
Bus 003 Device 002: ID 27c6:538d Shenzhen Goodix Technology Co.,Ltd. FingerPrint

And it works with the driver from AUR.

Please try again to flash the device (with run_538d.py) and copy here the output

And also of this

pacman -Qqe | grep fprint

and this

systemctl status fprintd.service

i also tried using
systemctl start fprintd.service
systemctl enable fprintd.service
There still is no option of fingerprint login or The Fingerprint GUI still says No devices found.

guiodic · 7 May 2022 00:26

I don’t understand, it worked for me.
The only thing I can think of is that it’s a permissions problem.
Try adding your user to the input group

sudo usermod -a -G input rk10

(where rk10 is your username, if it is different change it accordingly)

then reboot and try again

fprintd-enroll

If this doesn’t work try to ask to the driver developers here: Discord

LM10 · 7 May 2022 13:19

Impossible to enroll: GDBus.Error:net.reactivated.Fprint.Error.NoSuchDevice: No devices available
samething brother. Thanks for your time

Spyrou · 13 May 2022 15:36

Hi @Riquez ,
My device is also Unsupported. I have the Goodix Fingerprint Sensor, on my XPS 9310. The USB ID of my FingerPrint sensor is 27c6:533c.
But thanks to other people feedback I got it to work.
Also by removing libfprint and replacing it with libfprint-tod-git , as per the arch wiki.
Please do not despair: there can be solutions.
Best is to create a specific post about your device and hope someone with a similar one will be able to help.
Cheers

Riquez · 13 May 2022 15:47

Thanks for your helpful information!
It’s good to know it may still be possible to activate, I will look into it further.
