i3lock - improved screen locker

This is just a re-patched version of i3lock with the commits from i3lock-color; all the credit for the color functionality goes to eBrnd !

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 an image (JPG or PNG), 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.

Additional features in this fork

• You can also specify additional options, as detailed in the manpage. This includes, but is not limited to, the following: - Color options for the following:
  • verification ring
  • interior ring color
  • ring interior line color
  • key highlight color
  • backspace highlight color
  • text colors for most/all strings
  • Changing all of the above depending on PAM's authentication status - Blurring the current screen and using that as the lock background
    - Showing a clock in the indicator - refreshing on a timer, instead of on each keypress - Positioning the various UI elements - Changing the ring radius and thickness, as well as text size - A new bar indicator, which replaces the ring indicator with its own set of options
  • An experimental thread for driving the redraw ticks, so that things like the bar/clock still update when PAM is blocking

Building

Before you build - check and see if there's a packaged version available for your distro (there usually is, either in a community repo/PPA).

If there's no packaged version available - think carefully, since you're using a forked screen locker at your own risk.

If you want to build a non-debug version, you should tag your build before configuring. For example: git tag -f "git-$(git rev-parse --short HEAD)" will add a tag with the short commit ID, which will be used for the version info. Issues asking about ASAN/complaints about i3lock-color being slow / etc will likely be closed.

i3lock now uses GNU autotools for building; you'll need to do something like autoreconf -i && ./configure && make to build.

Running i3lock

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

A sample script is included in this repository. Here is a short clip of that script in action!

On OpenBSD the i3lock binary needs to be setgid auth to call the authentication helpers, e.g. /usr/libexec/auth/login_passwd.
