Change the lock screen program

1. Configure gnome-flashback to Disable Built-in Lockscreen

By default gnome-flashback handles the lock screen for Regolith. This can be adjusted by modifying it’s configuration via the gsettings command line program:

$ gsettings set org.gnome.gnome-flashback screensaver false

2. Cause Your Lock screen program to Run from i3 Keybinding

Specify the following override line in your ~/.config/regolith/Xresources file (substituting your-script.sh with the command you wish to use for the locking your screen):

i3-wm.program.lock: your-script.sh

For example, assuming you have i3lock installed:

$ echo "i3-wm.program.lock: /usr/bin/i3lock" >> ~/.config/regolith/Xresources
