Installation
Download and install the uestibulum theme:
git clone https://github.com/jdbernard/lightdm-uestibulum.git
sudo cp -r lightdm-uestibulum /usr/share/lightdm/uestibulum
Change the webkit-theme value in /etc/lightdm/lightdm-webkit2-greeter.conf:
[greeter]
webkit-theme = uestibulum
Configure lightdm to use the webkit2 greeter by creating the
/usr/share/lightdm/lightdm.conf.d/60-lightdm-webkit2-greeter.conf file with
the following contents:
[Seat:*]
greeter-session=lightdm-webkit2-greeter
Disable the GTK greeter:
sudo mkdir /usr/share/lightdm/lightdm.conf.d.disabled
sudo mv /usr/share/lightdm/lightdm.conf.d/60-lightdm-gtk-greeter.conf /usr/share/lightdm/lightdm.conf.d.disabled
On distributions other than Ubuntu, lightdm configuration files may be in different locations. Consult your distribution's documentation for details.
