Display Manager in XFCE

HI team

I am still very new on XFCE ( learning in progress ) . I have finally
done the configuration of XFCE from scratch ( building my own distro
just for fun ) icons and fonts are working fine ( proud of it )

However now I am facing the problem that just the root account can
start the xfce session . I have chose lightDM as my display manager  (
after reading some threads and forums ) .

After few days compiling it and their dependencies ( libxklavier,
iso-codes, libgp.. and some others ) I have finally build the lightDM
and the lightDM-gtk-greeter

Now my problem is .. how do I set it up ( yea shame on me,  I know )
. I have being checking the fedora spec file :


And they provide the ligthDM.service that systemd will use .

Reading the arch linux wiki :


They mention the option of :

$ lightdm --test-mode --debug

But for me, with my binaries it is showing me the error:

[+0.00s] DEBUG: Logging to /var/log/lightdm/lightdm.log

[+0.00s] DEBUG: Seat: Failed to find session configuration default
[+0.00s] DEBUG: Seat: Failed to create greeter session

I know that I still need to configure the service in order to make the
greeter start every time I boot up, how can I know if the greeter will
work before set it as default boot up service

In summary

Does anybody has a better documentation of lightDM where I can read ?

Has anybody configure lightDM in XFCE before with these problems

Thanks a lot for all your help

BTW: I have build lightdm like

 %configure --disable-tests --enable-liblightdm-gobject --disable-static

and lightDM-gtk-greeter:

%configure --with-gtk2
