# lightdm.sh — LightDM + GTK greeter (cyberqueer-themed)
|
|
#
|
|
# The default greeter for HyprLua. LightDM's GTK greeter reuses the cyberqueer
|
|
# GTK theme shipped in this repo (gtk-themes/cyberqueer), so it matches the rest
|
|
# of the desktop, and it is driven by a single trivial INI file
|
|
# (/etc/lightdm/lightdm-gtk-greeter.conf) — the simplest config of the
|
|
# LightDM/LXDM/GDM options.
|
|
#
|
|
# This module is self-contained (installs the theme + skull background itself)
|
|
# so it can also be selected on its own from modules.conf. It is mutually
|
|
# exclusive with the ly greeter module. Enabling LightDM here disables the other
|
|
# greeters (greetd, ly) and the tty1 getty so exactly one display manager runs.
