I am looking for the Linux driver of my fingerprint Goodix 27c6:538d, on my laptop Dell Inspiron 7506 2-in-1, with Ubuntu 20.04.

I followed this method but it doesn't solve the problem, the fingerprint login option still doesn't appear in Ubuntu Settings \ Users.

Command cat /lib/udev/rules.d/60-libfprint-2-tod1-goodix.rules returns :

# Goodix Fingerprint Sensor
SUBSYSTEM=="usb", ATTRS{idVendor}=="27c6", ATTRS{idProduct}=="538c", ATTRS{dev}=="*", TEST=="power/control", ATTR{power/control}="auto", MODE="0660", GROUP="plugdev"
SUBSYSTEM=="usb", ATTRS{idVendor}=="27c6", ATTRS{idProduct}=="538c", ENV{LIBFPRINT_DRIVER}="Goodix Fingerprint Sensor" 
SUBSYSTEM=="usb", ATTRS{idVendor}=="27c6", ATTRS{idProduct}=="533c", ATTRS{dev}=="*", TEST=="power/control", ATTR{power/control}="auto", MODE="0660", GROUP="plugdev"
SUBSYSTEM=="usb", ATTRS{idVendor}=="27c6", ATTRS{idProduct}=="533c", ENV{LIBFPRINT_DRIVER}="Goodix Fingerprint Sensor"
SUBSYSTEM=="usb", ATTRS{idVendor}=="27c6", ATTRS{idProduct}=="530c", ATTRS{dev}=="*", TEST=="power/control", ATTR{power/control}="auto", MODE="0660", GROUP="plugdev"
SUBSYSTEM=="usb", ATTRS{idVendor}=="27c6", ATTRS{idProduct}=="530c", ENV{LIBFPRINT_DRIVER}="Goodix Fingerprint Sensor"
SUBSYSTEM=="usb", ATTRS{idVendor}=="27c6", ATTRS{idProduct}=="5840", ATTRS{dev}=="*", TEST=="power/control", ATTR{power/control}="auto", MODE="0660", GROUP="plugdev"
SUBSYSTEM=="usb", ATTRS{idVendor}=="27c6", ATTRS{idProduct}=="5840", ENV{LIBFPRINT_DRIVER}="Goodix Fingerprint Sensor"

I notice that command lsusb returns a different version of fingerprint reader : 27c6:538d, not listed in the list mentioned above.

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

I am wondering about something. Maybe 27c6:538d is not very different from 538c, so maybe the 538c driver can be used for my 538d device? Or maybe it just needs small modifications that can be done manually?

Thank you in advance for your help

I don't think a driver for 27c6:538d is available yet. A bug report has already been filed in the libfprint package for the same. And unfortunately it may not be as easy as modifying 538c.
