In my debian machine, it will show the below log, and I find that
lightdm_get_session will be called successfully.

But in guix, lightdm_get_sessions seem to not be called, for I can not
find string "Run lightdm_get_session function. " in log file, just like
the below:

liblightdm-gobject shared library seem to be loaded, for when I remove this lib,
gtk-greeter will not show.
but why lightdm_get_sessions function do not be called while
liblightdm-gobject is loaded?

Finally pushed to master (see commits b9d7e15f9f and 3a8e19a61d), after
I had some time to properly review and test it. I've adjusted the
commit messages a bit, and used this Scheme trick to reuse more of the
install phase arguments:
--8<---------------cut here---------------start------------->8---
;; matching tests.
- (unsetenv "LC_ALL"))))))
+ (unsetenv "LC_ALL")))
+ (replace 'install
+ (lambda* (#:key make-flags #:allow-other-keys #:rest args)
+ ;; Override the sysconfdir flag only for the installation phase,
+ ;; as it attempts to write the sample config files to /etc and
+ ;; fail otherwise.
+ (define make-flags*
+ (append make-flags (list (string-append "sysconfdir="
+ #$output "/etc"))))
+ (apply (assoc-ref %standard-phases 'install)
+ (append args (list #:make-flags make-flags*))))))))
(inputs

Closing.
