Lightdm-GTK-Greeter-Settings doesn t start , have to enable it from terminal

I have to use this command in Terminal in order to start it; Any ways to start it normally .

sudo lightdm-gtk-greeter-settings

Fixed 2 issues in one with the reinstall . (the Plymouth issue I also had )

Got fixed after a fresh install, wonder why it didn t started before, I bet I ll never know .
