Can't change lightdm greeter

[PRISONER]

I want the lightdm greeter to be (lightdm-slick-greeter) but even after changing the greeter in lightdm.conf file, greeter did not changed its always the default one.

in arch wiki it was mentioned to change (greeter-session=lightdm-slick-greeter), and I have done that.

and the slick-greeter was installed too.
ls -1 /usr/share/xgreeters/
output:
lightdm-gtk-greeter.desktop lightdm-slick-greeter.desktop

Maybe search the forum for an answer first? Try following this post:

Currently the lightdm-gtk-greeter-settings won’t save a new greeter background unless you open it with sudo and use the folder /usr/share/pixmaps for your preferred wallpaper.

You need to make your changes in /etc/lightdm/slick-greeter.conf. Here’s what I’m using:

[Greeter]
