How To Install i3lock on CentOS 7
Introduction
In this tutorial we learn how to install i3lock on CentOS 7.
What is i3lock
i3lock improves slock by making it fork() and therefore combinable with commands to suspend your computer. Additionally, instead of turning off your screen via DPMS and/or displaying a black screen, i3lock displays a white screen so you can see if your computer failed to resume from suspend or if your screen is just locked. Also, when entering a wrong password, i3lock does not call XBell(). This is important because i3lock/slock think you’ve entered a password when resuming from suspend, at least sometimes.
