[lmtr0]

Hi there, I have tried using this library with the 27c6:538d Shenzhen Goodix Technology Co.,Ltd. FingerPrint reader, but when I started rebooted the system i got this error:

╰─○ sudo systemctl status python3-validity
× python3-validity.service - python-validity driver dbus service

Hi There, I've got a similar problem on Dell Inspiron 5402, but in my case the packages didn't even installed properly.

Oh what a coincidence, I am on a dell Inspirion 5502

anyone know what up with this? or what info is needed to add it?

[lmtr0]

the device encrypts the information before it's pass down to the driver, so If we don't know the decryption key, we can't really interact in a reliable way with the reader. more about this however they are working on it more about it on this issue
