LockScreen

First, turn off dunst

killall -SIGUSR1 dunst && echo "off" > /tmp/dunststatus;

Turn off the music if it is playing.

MPC_STATE=$(mpc | sed -n '2p' | cut -d "[" -f2 | cut -d "]" -f1)
if [[ $MPC_STATE == "playing" ]]; then
  mpc pause
fi

Then take a screenshot and process it.

temp_file="/tmp/screen.png"

rm -f $temp_file

maim $temp_file
convert $temp_file -scale 10% -scale 1000% $temp_file

Finally, lock the screen using i3lock.

i3lock --no-unlock-indicator --ignore-empty-password --nofork --image=$temp_file && killall -SIGUSR2 dunst && echo "on" > /tmp/dunststatus
revert() {
    xset dpms 0 0 0
}
trap revert HUP INT TERM
# turn off screen after 5 seconds
xset +dpms dpms 5 5 5

# Parameters
temp_file="/tmp/screen.png"
icon="$HOME/Pictures/Evil_Rick_Sprite.png"
width=1920
height=1080
blur_factor=6
lock_blur_factor=0

# Take the screen shot, blur the image and add the icon
ffmpeg -f x11grab -video_size "${width}x${height}" -y -i $DISPLAY -i $icon -filter_complex "boxblur=$blur_factor:$blur_factor,overlay=(main_w-overlay_w)/2:(main_h-overlay_h)/2,boxblur=$lock_blur_factor:$lock_blur_factor" -vframes 1 $temp_file

# Alternative
# maim -d 1 $temp_file
# convert -blur 0x8 $temp_file $temp_file
# convert -composite $temp_file $icon -gravity South -geometry -20x1200 $temp_file

# Lock the screen with the image
i3lock --no-unlock-indicator --ignore-empty-password --show-failed-attempts --nofork --image=$temp_file

# Remove the screenshot
rm $temp_file

# Don't turn off screen when back from lock
revert

elif [ $1 == "umount" ]; then
    if umount /home/thomas/mnt/NAS/; then
        dunstify --replace=58249 'NAS' 'Successfully unmounted'
    else
