Web Greeter for LightDM

A modern, visually appealing greeter for LightDM, that allows to create web based themes with HTML, CSS and JavaScript.

This is a try to update the Antergos web-greeter, following what they left.

As this is based on the master release, which does some API changes, actual themes would need to do changes to work correctly.

Checkout nody-greeter, a greeter made in Node.js with Electron! (Actually, faster than Web Greeter)

Gruvbox and Dracula themes!

Theme JavaScript API

Antergos documentation is no longer available, although it is accesible through Web Archive. Actual documentation is available in gh-pages.

You can access the man-pages man web-greeter for some documentation and explanation. Also, you can explore the provided themes for real use cases.

Brightness control

To control the brightness inside the greeter, I recommend to use acpilight replacement for xbacklight.

udev rules are needed to be applied before using it. Then, lightdm will need to be allowed to change backlight values, to do so add lightdm user to video group: sudo usermod -a -G video lightdm

If you don't want to or don't have a compatible device, disable it inside /etc/lightdm/web-greeter.yml (disabled by default)

Battery status

acpi is the only tool you need (and a battery).

You can disable it inside /etc/lightdm/web-greeter.yml (disabled by default)

Debugging

You can run the greeter from within your desktop session if you add the following line to the desktop file for your session located in /usr/share/xsessions/: X-LightDM-Allow-Greeter=true.

You have to log out and log back in after adding that line. Then you can run the greeter from command line.

Themes can be opened with a debug console if you set debug_mode as true inside /etc/lightdm/web-greeter.yml. Or, you could run the web-greeter with the parameter --debug. I recommend to use the last one, as it is easier and handy.

web-greeter --debug

Note: Do not use lightdm --test-mode as it is not supported.
