<SOLVED>Fingerprint scanner doesn't work in Lenovo X1 carbon 7th

HI,

I follow fprintd wiki guide to use fingerprint scanner on login with lightdm as well as sudo in terminal.  However, it doesn't work.  I use xfce4 on X1C7 with default polkit-gnome. 

I tried to install Fedora 33 and the finger scanner worked flawlessly.  So it is not firmware issue.  Any help would be appreciated. 

Thank you.

I figured it out.  The arch wiki suggested to put in pam_d conf files

auth        sufficient      pam_unix.so try_first_pass likeauth nullok
auth        sufficient      pam_fprintd.so

I switched the order and it worked great.

auth        sufficient      pam_fprintd.so
auth        sufficient      pam_unix.so try_first_pass likeauth nullok
