This is my own copy of i3lock, consisting of the following tweaks:

• Display changes on key-strokes and escape/backspace.
• Added 12-hour clock to the unlock indicator and periodic updater so time stays relevant.
• The unlock indicator will always be displayed, regardless of state. (Originally it was only shown after initial keypress)
• Command line arguments to customize colors. Each (optional) argument will accept a color in hexadecimal format.
  • -o color Specifies verification color
  • -w color Specifies wrong password/backspace color
  • -l color Specifies default/idle color
  • The given colors will be used as-is for the lines and text for their respective states. The colors will automatically be lightened slightly and used with lower opacity (20%) for the circle fill.
  • If no colors are specified it defaults to green/red/black for verify/wrong/idle respectively.

Make sure you have the following libraries installed in addition to the packages in the requirements section below.

libxkbcommon-dev libxkbcommon-x11-dev libpam0g-devl

Run the following commands:

git clone https://github.com/Lixxia/i3lock.gitcd i3lockautoreconf -fimkdir -p build && cd build../configuremake && sudo make install

i3lock> is a simple screen locker like slock.After starting it, you will see a white screen (you can configure thecolor/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 screenafter waking up your computer from suspend to RAM)

• You can specify either a background color or a PNG image which will bedisplayed while your screen is locked. Note that i3lock is not an imagemanipulation software. If you need to resize the image to fill the screenor 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.

Seethe i3lock home page.

• pkg-config
• libxcb
• libxcb-util
• libpam-dev
• libcairo-dev
• libxcb-xinerama
• libxcb-randr
• libev
• libx11-dev
• libx11-xcb-dev
• libxkbcommon >= 0.5.0
• libxkbcommon-x11 >= 0.5.0

Simply invoke the 'i3lock' command. To get out of it, enter your password andpress enter.

On OpenBSD thei3lock binary needs to be setgidauth to call theauthentication helpers, e.g./usr/libexec/auth/login_passwd.

We recommend you use the provided package from your distribution. Do not buildi3lock unless you have a reason to do so.

First install the dependencies listed in requirements section, then run thesecommands (might need to be adapted to your OS):

autoreconf --force --installrm -rf build/mkdir -p build && cd build/../configure \  --prefix=/usr \  --sysconfdir=/etc \  --disable-sanitizersmake
