I use below code to test:
1. lightdm-gtk-greeter code:

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?
