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/regolith3/Xresources file (substituting your-script.sh with the command you wish to use for the locking your screen):

Regolith version 3.0 onward replaces “i3-wm” with “wm” in Xresource keys. The content on this page has been updated for Regolith 3.0+. If you are using an earlier version, use “i3-wm” instead of “wm” in the key names below. For example wm.foo.bar changes to i3-wm.foo.bar for Regolith 1.x and 2.x.

wm.program.lock: your-script.sh

For example, assuming you have i3lock installed:

$ echo "wm.program.lock: /usr/bin/i3lock" >> ~/.config/regolith3/Xresources
