Ubuntu之下如何开启壁纸自动切换

选择一个图片文件夹，将需要用到的壁纸放在该文件下在该文件夹下运行如下脚本：

#!/usr/bin/env python# -*- coding: utf-8 -*-# Name: slidexml.py# Author: EthanZ6174# Email: <heracles.621@gmail.com># Site: http://www.noslog.com# Licence: GPLv3# Version: 091127import glob, osimport shutilimport timecurdir = os.getcwd()os.chdir(curdir)currentFilelist = glob.glob('*.*')currentImageFiles = glob.glob('*.jpg')currentTime = time.localtime()length = len(currentImageFiles)for i in currentFilelist: if i == 'backgroundslide.xml':  os.remove(i)f = file('backgroundslide.xml', 'w')f.write('<background>\n')f.write('\t<starttime>\n')f.write('\t\t<year>' + str(currentTime.tm_year) + '</year>\n')f.write('\t\t<month>' + str(currentTime.tm_mon) + '</month>\n')f.write('\t\t<day>' + str(currentTime.tm_mday) + '</day>\n')f.write('\t\t<hour>' + str(currentTime.tm_hour) + '</hour>\n')f.write('\t\t<minute>' + str(currentTime.tm_min) + '</minute>\n')f.write('\t\t<second>' + str(currentTime.tm_sec) + '</second>\n')f.write('\t</starttime>\n')f.write('<!--This animation will start at the time it created-->\n')for i in currentImageFiles: length = length - 1 print length #print curdir #print currentImageFiles[1] f.write('\t<static>\n') f.write('\t\t<duration>595.0</duration>\n') f.write('\t\t<file>' + curdir + '/' + currentImageFiles[length] +'</file>\n') f.write('\t</static>\n') f.write('\t<transition>\n') f.write('\t\t<duration>5.0</duration>\n') f.write('\t\t<from>' + curdir + '/' + currentImageFiles[length] + '</from>\n') if length >= 1:  f.write('\t\t<to>' + curdir + '/' + currentImageFiles[length-1] + '</to>\n') if length <1:  f.write('\t\t<to>' + curdir + '/' + currentImageFiles[len(currentImageFiles)-1] + '</to>\n') f.write('\t</transition>\n')f.write('</background>\n')f.close()

?3. 将生成的background.xml加入桌面背景选择中
