    Re: HowTo: Wallpaper Changer for Xubuntu (Xfce)

    Nice. Problem is that my computer has a tendency of freezing up during the changes, and when I'm playing games or watching movies, I'd prefer it to not switch, so I whipped up a little script that temporarily lowers it scheduling priority.

    Code:
    #!/bin/bash
    #change-background
    
    #get the pid for xfdesktop
    pid=`ps -e | grep xfdesktop | gawk '{print $1}'`
    
    #a regular expression containing the names of the processes
    #that will defer the switching
    deferred='(mplayer|xgame)'
    
    if [[ -z $pid ]] && [[ -n `ps -e | egrep $deferred` ]]; then
    
    else
        renice 19 -p $pid
        kill -USR1 $pid
        renice 0 -p $pid
    fi

    I'm not smart like you. Is it on line 9 that I could change it to something like...

    Code:
    deferred='(mplayer|xgame|vlc)'
    ?

    Yes, exactly. Any process that contains the three letter combination 'vlc' (like wxvlc, for instance) will then disable the script from changing the background.

    I used this script and it is working perfectly, thanks.

    It makes life so much easier when things just work! I added an icon so that if I don't feel like using that image then I can switch to a new one.

    Thanks for the tip.

    Re: HowTo: Wallpaper Changer for Xubuntu (Xfce)

    I ended up using this crontab line to avoid trying to send signals to other users' xfdesktop processes:

    Code:
    */10 * * * * kill -USR1 $(ps awxu | grep -E '^loginname[ \t]+.+[0-9:]+ /usr/bin/xfdesktop' | awk '{print $2}') >/dev/null 2>&1
    Replace the underlined "loginname" with your login name.

    Re: HowTo: Wallpaper Changer for Xubuntu (Xfce)

    I would suggest easyr is this.
    After putting wallpaper list and installing cron
    just open crontab -e
    paste there just */5 * * * * export DISPLAY=:0; /usr/bin/xfdesktop -reload
    save and exit with ctrl+shift+X and then Y and Enter
    and thats it.
    it will make every minute that can be divided by 5 to reload xfdesktop so basicly every 5 minuts
