I tried cloning and checking out the multi-monitor branch but when I ran ./betterlockscreen, I got "i3lock-color: command not found".

I also tried the fork jeffmhubbard/multilockscreen, which works well but the text is not aligned properly in the box.
Edit: text and i3lock circle are both not aligned properly with the box.

What can I do to get either of these two repos to work? :)
