What is the address of login screens in kubuntu 14.04 KDE 4.13.3?

[Shabakthanai]

I am having difficulty getting my custom login screen installed. In system settings>login screen (LightDM), I select my custom wallpaper, enter my sudo password, however it does not install. My thought is to locate the folder where login screen (LightDM) is, and copy and paste my custom image. Will this solve my problem? Thanks!

How to change the lightDM KDE greeter background and why it is not working (white background): http://askubuntu.com/questions/29611...change-kubuntu

The lightDM KDE greeter it reading/writing the path to the /etc/lightdm/lightdm-kde-greeter.conf

As example, lightdm-kde-greeter.conf, at here:

[greeter]
theme-name=classic

[greeter-settings]
Background=/lib/plymouth/themes/my-plymouth/my-wallpaper.png
BackgroundKeepAspectRatio=true
GreetMessage=Welcome to %hostname%
Logo=

Thanks my friend. I needed to have group and others able to read in the properties section of the image. It works fine now.
