The log files for lightdm is found at /var/log/lightdm/. It might give a clue.

Do you have or need any nfs mounted file systems? The rpc-statd-notify.service is part of the nfs related services you only need if you need some nfs mounted file system.

Thanks for reply.
Its seems issue in Lightdm+Wayland.
For test i am replace lightdm with gdm and disable wayland in gdm config, result is Xorg starting automatically.
So is there solution how bypass wayland in lightdm?
