Hi, I am using Elementary OS 7. I need to add "greeter-setup-script" to lightdm.conf: greeter-setup-script=/etc/lightdm/monitor1-off.sh However there is no config file under /etc/lightdm I already tried to add the custom config file in /etc/lightdm/lightdm.conf.d but it did not work. Anyone can help me fixing this? btw, I am trying to disable laptop monitor at login screen with greeter-seupt-script. Thanks.
