I use pcmanfm to display wallpapers on my desktop. The location of the conf file for pcmanfm is ~/.config/pcmanfm/lubuntu. In this file the wallpaper is simply set in this form:

wallpaper=/PATH/TO/IMAGE/FILE/image.jpg

How would I go about getting that information to the configuration file of the lightdm greeter? /etc/xdg/lubuntu/lightdm/lightdm-gtk-greeter.conf

The background in the configuration file of the greeter is set like this:

background=/PATH/TO/IMAGE/FILE/image.jpg

Is there any way that I could link it, or something else with the desired result?

LightDM use AccountsService to get user's wallpaper.

I do not use pcmanfm, but at first look it seems that pcmanfm do not interact with AccountsService to update information about wallpaper.

There are 2 options:

  1. Wait for needed pcmanfm functionality (or just search for related bugs - maybe it's already reported but not implemented).

  2. You can edit "/var/lib/AccountsService/users/$USER" file. Add following line to change your wallpaper at login screen for specified user:

    background=path/to/image
