I uninstalled lightdm and reinstalled it. Following that, when I try to login I get a failure to authenticate error and the only way to get access is via VT (ctrl+alt+f4) and then 'startx'.

I am using an xfce desktop in Ubuntu 21.10.

Dmesg:

An suggestions how to solve this please?

Edit:
/etc/lightdm/lightdm.conf.d:
