swaylock with image per-output

sway-lock.sh

#!/bin/bash
 
# Dependencies:

Had to make some slight changes:

• Iterate over only active outputs
• Use a different blurring program, to make it a little faster.

This is my edited version:

#!/bin/bash
 
# Dependencies:
# imagemagick
# swaylock
# grim
# corrupter (https://github.com/r00tman/corrupter)
 
IMAGE=/tmp/i3lock.png
LOCK=~/stow/bin/assets/stop.png
LOCKARGS=""

for OUTPUT in `swaymsg -t get_outputs | jq -r '.[] | select(.active == true) | .name'`
do
    IMAGE=/tmp/$OUTPUT-lock.png
    grim -o $OUTPUT $IMAGE
    corrupter -mag 1 -boffset 1  -meanabber 20 $IMAGE $IMAGE
    composite -gravity center $LOCK $IMAGE $IMAGE
    LOCKARGS="${LOCKARGS} --image ${OUTPUT}:${IMAGE}"
    IMAGES="${IMAGES} ${IMAGE}"
done
swaylock $LOCKARGS
rm $IMAGES

Nice, thanks!

how do i run this script from below sway config file?

exec swayidle -w \
         timeout 600 'swaylock -f -c 000000' \
         timeout 900 'swaymsg "output * dpms off"' \
              resume 'swaymsg "output * dpms on"' \
         before-sleep 'swaylock -f -c 000000'

@fuzunspm replace swaylock -f -c 000000 with full path to this script.
Or place this script in one of your $PATH directory such as /usr/local/bin/ and call as sway-lock.sh.

Thank you
