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
