+# i3lock-fancy-multimonitor
+The idea for this project was shamelessly copied from [meskarune](https://github.com/meskarune)'s [i3lock-fancy](https://github.com/meskarune/i3lock-fancy).
+
+It uses [scrot](http://freecode.com/projects/scrot) to take a screenshot of the desktop, then [ImageMagick](http://www.imagemagick.org/) blurs the image and adds a lock icon and text.
+
+By using information from [xrandr](http://www.x.org/wiki/Projects/XRandR/) and basic math, this script supports multiple monitor setups, displaying the icon and text centered on all screens.
+
+The lock icon is different from the original project, with a transparent black circle around it. The text is also an image, making it easier to customize (and to put it at the correct position). Finally, it uses vanilla [i3lock](https://github.com/i3/i3lock) instead of [i3lock-color](https://github.com/eBrnd/i3lock-color). The author of i3lock-color [is not maintaining it anymore](https://github.com/eBrnd/i3lock-color/issues/6). If you want to customize the colors of i3lock, the recommended version of i3lock-color is [this one](https://github.com/Arcaena/i3lock-color), maintained by [Chris Guillott](https://github.com/Arcaena).
+
+## Installation
+Make sure you have all the dependencies:
+
+```
+sudo apt-get install scrot imagemagick i3lock
+```
+
+Copy the `lock` script along with the images to some place on your system (e.g.: the i3 folder) and give it execution permission:
+
+```
+git clone https://github.com/guimeira/i3lock-fancy-multimonitor.git
+cp -r i3lock-fancy-multimonitor ~/.i3
+chmod +x ~/.i3/i3lock-fancy-multimonitor/lock
+```
+
+Create a key binding on your i3 config file (in this example I'm using $mod+p):
+
+```
+echo "bindsym \$mod+p exec /home/<your username>/.i3/i3lock-fancy-multimonitor/lock" >> ~/.i3/config
+```
+
+Now reload the i3 configuration file. By default, the key binding is `$mod+Shift+c`.
