You have been subscribed to a public bug:

If a PAM module with GUI interface for alternative authentication
methods (like fingerprint authentication) is used, this module needs
information about the xdisplay to connect to for showing up it's widget.
Therefore PAM has two enviroment variables to be setup by the
application before calling the "pam_authenticate" function. These
variables are PAM_XDISPLAY and PAM_TTY, both to be set to the current
display number (e.g. ":0"). Alternatively the environment variables
XDISPLAY and XAUTHORITY can be set, so the PAM module can get the
information by calling "getenv()".
