Login wallpaper for XFCE

I am not a fan of default wallpapers shipped with recent version of Manjaro. So, how to change a default wallpaper on XFCE login screen? Changing desktop wallpaper is simple, but it took me a while to find where and how to change the greeting wallpaper that is displayed on login screen.

To change the wallpaper you must edit the greeting configuration file (of course use your favourite editor, it does not need to be vim):

sudo vim /etc/lightdm/lightdm-gtk-greeter.conf

You will see a configuration similar to the below. Just change the path with background to the image of your choice.

[greeter]
theme-name = Matcha-dark-sea
icon-theme-name = Papirus-Dark-Maia
background = /usr/share/wallpapers/manjaro-arm/generic/aks.png
screensaver-timeout = 0
