betterlockscreen

A simple lock script for i3lock

Most of i3lock script out there converts your defined image to add blur, glitch or dim effect to image and it feels so slow and btw who needs dynamic lock background, its not like I change lockscreen background every 5 minutes. I wanted something that was fast and still should have all the effects I want for lockscreen background.

This script generates or already caches the variant for your custom images before hand so they can be later used any number of time as lockscreen background, without the need to apply same effect again and again

exec betterlockscreen -w

If you are i3wm user, add following line to your i3config (~/.config/i3/config or ~/.i3/config)

custom shortcut to lockscreen

# custom keybinding to lockscreen, use --lock dim or --lock blur below for different backgrounds
bindsym $mod+shift+x exec betterlockscreen --lock

# Update image cache
# no longer required as cached images are permanently stored

exec --no-startup-id betterlockscreen -w

OR

use following if you would like to be surprised by random wallpaper from directory of your choice on each startup

# where Pictures/Wallpapers is the directory you would want to get random wallpapers from
exec --no-startup-id betterlockscreen -u ~/Pictures/Wallpapers

# add this only if you want to use same random image as desktop background too (you might want to)
# it might not work as it takes few seconds for images to be cached,
# try adding delay of 5 seconds if thats the case
exec --no-startup-id betterlockscreen -w
