i3lock - improved screen locker
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:
-
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. Note that i3lock is not an image
manipulation software. If you need to resize the image to fill the screen
or similar, use existing tooling to do this before passing it to i3lock. -
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.
