i3lock - improved screen locker
|
|
===============================
|
|
[i3lock](https://i3wm.org/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.

Running i3lock
|
|
-------------
|
|
Simply invoke the 'i3lock' command. To get out of it, enter your password and
|
|
press enter.
|
|
|
|
On OpenBSD the `i3lock` binary needs to be setgid `auth` to call the
|
|
authentication helpers, e.g. `/usr/libexec/auth/login_passwd`.

|
|
Building i3lock
|
|
---------------
|
|
We recommend you use the provided package from your distribution. Do not build
|
|
i3lock unless you have a reason to do so.
|
|
|
|
First install the dependencies listed in requirements section, then run these
|
|
commands (might need to be adapted to your OS):
|
|
```
|
|
autoreconf --force --install
|
|
|
|
rm -rf build/
|
|
mkdir -p build && cd build/
|
|
|
|
../configure \
|
|
--prefix=/usr \
|
|
--sysconfdir=/etc \
|
|
--disable-sanitizers
|
|
|
|
make
|
|
```
