Bug#524561: Wrote script to change the wall paper

[Chris Dos]

I found a way to change the wallpaper from the command line.  So I modified a 
script that I made to change the
wallpaper in e17.  I still think this is a bug, but this might be useful to 
others out there that are having
the same problem:

<- Begin Script ->
#!/bin/bash

export PATH="/sbin:/bin:/usr/sbin:/usr/bin:/usr/local/sbin:/usr/local/bin"

ROTATEDELAY=120

WORKDIR=/tmp/.rotate_wallpaper

FILELIST=$WORKDIR/.imagefiles

# Location of the directories of your image files.
IMAGEFILES="$HOME/Images/1920x1200_Wall_Wapers \
                $HOME/Images/Aircraft \
                $HOME/Images/Animals    \
                $HOME/Images/Astronomy \
                $HOME/Images/Cars \
                $HOME/Images/DigitalBlasphemy \
                $HOME/Images/Fantasy \
                $HOME/Images/LinuxWallPapers \
                $HOME/Images/Scenery \
                $HOME/Images/Sci-Fi \
                $HOME/Images/Second_Nature \
                $HOME/Images/Ships"


if [ ! -d $WORKDIR ]
then
        mkdir $WORKDIR
fi

if [ -e FILELIST ]
then
        rm -f FILELIST
fi

# Build file list
for I in $IMAGEFILES
do
        find $I -type f \( -name '*.jpg' -o -name '*.png' -o -name '*.gif' \)>> 
$FILELIST
done

# Load list of images into array and remove unneeded file.
oIFS=$IFS IFS=$'\n' LINES=($(<"$FILELIST")) IFS=$oIFS
rm $FILELIST


# Pick random image, set the background, and loop forever.
cd $WORKDIR
while :
do
        n=${#lin...@]}
        r=$((RANDOM % n))
        IMAGE="`echo ${LINES[r]}`"
        xfconf-query -c xfce4-desktop -p /backdrop/screen0/monitor0/image-path 
-s ""
        xfconf-query -c xfce4-desktop -p /backdrop/screen0/monitor0/image-path 
-s "${IMAGE}"
        sleep $ROTATEDELAY
done
<- End Script ->
