Build status

Usage

Once the package is installed, set the correct greeter session in /etc/lightdm/lightdm.conf:

[Seat:*]
greeter-session=lightdm-prologin-greeter

Configuration

The greeter reads /etc/lightdm/lightdm-prologin-greeter.conf at startup. This is an INI file that can contain the following:

[greeter]
; Page to load. If it fails, the greeter fallbacks to a built-in theme.
url = "http://greeter/"
; A valid QColor string to use as solid background color while loading the URL.
; https://doc.qt.io/qt-5/qcolor.html#setNamedColor
background_color = "#123abc"
; Seconds to wait for the page to load before falling-back.
fallback_delay = 3

Fallback theme

The built-in fallback theme is bare-bones but contains all that necessary bits to interact with the login manager, which isn't a trivial amount of code. To make it easy to customize the theme without having to create JS and CSS from scratch, the fallback theme references http://greeter/theme.css and http://greeter/theme.js after the default resources. By making these files available on the network, you can easily override the default look and behavior.
