+screen (you can configure the color/an image). You can return to your screen by

-.SH DIFFERENCES TO SLOCK
+.SH IMPROVEMENTS
 
-.B 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,
-.B i3lock
-displays a white (or colored in your favorite color) screen so you can see
-if your computer failed to resume from suspend or if your screen is just
-locked. Since version 1.1,
-.B i3lock
-can display images in XPM file format. Also, when entering a wrong password,
-.B i3lock
-does not call XBell(). This is important because
-.B i3lock/slock
-think you've entered a password when resuming from suspend, at least sometimes.
+.TP
+* 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)
