i3lock is a simple screen locker like slock. After starting it, you will see a white screen (you can configure the color/an image). You can return to your screen by entering your password.
Many little improvements have been made to i3lock over time:
-
Fuzzy option added. With that there is no image or solid color displayed when screen is locked. A blurring filter is applied to the screen.
-
i3lock forks, so you can combine it with an alias to suspend to RAM (run "i3lock && echo mem > /sys/power/state" to get a locked screen after waking up your computer from suspend to RAM)
-
You can specify either a background color or a PNG image which will be displayed while your screen is locked.
-
You can specify whether i3lock should bell upon a wrong password.
-
i3lock uses PAM and therefore is compatible with LDAP etc. On OpenBSD i3lock uses the bsd_auth(3) framework.

Simply invoke the 'i3lock' command. To get out of it, enter your password and press enter.
To run i3lock with the blurring, please use the --fuzzy option. The amount of
blurring can be changed with the --radius and --sigma flags. Please check
the man page.
On OpenBSD the i3lock binary needs to be setgid auth to call the
authentication helpers, e.g. /usr/libexec/auth/login_passwd.
