= How to change gdm or sddm to lightdm
[[BR]]
First, we will install everything necessary to have lightdm in our system. To do this, from the terminal:
[[BR]]
{{{
sudo pacman -S lightdm lightdm-gtk-greeter rebornos-lightdm-gtk-greeter-images lightdm-gtk-greeter-settings
}}}
[[BR]][[BR]]
Then we will customize the access. To do this, from the terminal:
[[BR]]
{{{
sudo echo "[greeter]" >> /etc/lightdm/lightdm-gtk-greeter.conf
sudo echo "theme-name = Flat-Plat-Blue" >> /etc/lightdm/lightdm-gtk-greeter.conf
sudo echo "icon-theme-name = Flat-Remix-Green" >> /etc/lightdm/lightdm-gtk-greeter.conf
sudo echo "background = /usr/share/pixmaps/rebornos.jpg" >> /etc/lightdm/lightdm-gtk-greeter.conf
sudo echo "default-user-image = /usr/share/pixmaps/avatar.png" >> /etc/lightdm/lightdm-gtk-greeter.conf
}}}

Theme=None
}}}
