Comment 8 for bug 1965931

Hi Marco,

I got a testing driver from FPC, it works fine in my side.

$ sudo add-apt-repository ppa:libfprint-tod1-group/ppa
$ sudo apt update
$ ubuntu-drivers list
libfprint-2-tod1-fpc
$ sudo apt install libfprint-2-tod1-fpc
$ sudo reboot

After boot up, I could enable fingerprint and use it to login. Just some
warning logs in system.

$ journalctl -b 0 | grep fprintd

Do you have any concerns that the FPC provide two so files?

libfprint-tod-fpcbep-9800-0.0.2.so is algorithm part which is called by libfprint-2-tod1-fpc-9800-0.0.2.so, the later one has tod interface.

Do you know the udev rules error above? The rules sounds good in my side. Thanks!
