CentOS 6.3のライブ壁紙の変更

centos 6.3とgnome 2.28.2で5分ごとに壁紙（背景）を変更する方法はありますか？このPythonスクリプトが見つかりました。

このスクリプトはUbuntu用で、私のシステムで実行しようとするとxmlファイルが生成されますが、機能しません。

誰でも私を助けることができますか？

これを行うためにアプリを使用したいと思います。過去にFedoraとCentOSで使用した2つの方法は次のとおりです。

ワパポート

GNOMEタスクバーで実行される小さなプログラム。

  • 以下からRPMをダウンロードできます。ここさまざまなFedora / CentOSバージョンに適用できます。
  • 主なウェブサイトはここ。
  • 主なgithubツリーは次のとおりです。ここ。

ボルパポーツSS

シェルスクリプト

これは画像のリストを繰り返すbashスクリプトです。

#!/bin/bash
#Default values
pictdir="$HOME/Pictures"
time=1h

#Wallpaper names
fnme=('wp1.jpg' 'wp2.jpg' 'wp3.jpg')

fin=${#fnme[@]}
let bck=$fin-1

#Exit if the script is already running, just in case
#Got this part of script somewhere in this forum
if pidof -x $(basename $0) > /dev/null; then
  for p in $(pidof -x $(basename $0)); do
    if [ $p -ne $$ ]; then
      echo "Script $0 is already running: exiting"
      exit
    fi
  done
fi

#This is where the desktop wallpaper changes
for (( i=0;i<$fin;i++ )); do
    sleep $time #wait for $time second(s)
    gconftool-2 --type string --set /desktop/gnome/background/picture_filename $pictdir/${fnme[${i}]}
    if [ $i -eq $bck ]; then
         let i=-1
    fi
done

を活用しますgconftool-2。まだ試していません。セントOS 6.xしかし、少し調整が必要かもしれませんが、使用しました。Fedoraの帽子そしてセントOS 5.x。台本は丁寧ですLinuxの質問スレッド。

バルチ

書くことができるここ。まだやってはいませんが効果があるそうですGNOME 2 & 3。 Wallchの良いレビューここ。
