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)
• 10/17/15 Added 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.

Example Usage

i3lock -i ~/.i3/background.png -c '#000000' -o '#191d0f' -w '#572020' -l '#ffffff' -e

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.

• You can specify whether i3lock should bell upon a wrong password.

• i3lock uses PAM and therefore is compatible with LDAP etc.
