Allows Ubuntu to implement scheduled switching similar to Windows 7 desktop Wallpaper

I don't know if you haven't noticed it when using Ubuntu. In Ubuntu, multiple wallpapers can be dynamically switched. In Win7, similar functions are available. The following is an experiment in Ubuntu10.10. The previous version should also work. The implementation principle is to use an xml file to record the wallpaper that can be switched. The following is an example self-contained in Ubuntu10.10. The default wallpaper of Ubuntu is stored in the/usr/share/backgrounds/directory.

First of all, the default Ubuntu wallpaper is stored in the/usr/share/backgrounds/directory, and there is a cosmos directory in this directory (meaning "Universe, the xml file in cosmos is used to implement the live desktop wallpaper switching function (see ).

We can easily find a sample of such xml, such as/usr/share/backgrounds/cosmos/background-1.xml, the content is as follows:

01
02
03 2009
04 08
05 04
06 00
07 00

I believe you have read this example and you all know how to set it. You only need to change the values of starttime, duration, transition, and other related parts, and then add the xml file when you change the desktop to achieve the desktop slide effect.

Do you have any trouble writing it by yourself? some cool people have made a fool program. Click here to download this omnipotent python applet that allows Ubuntu to implement a regular switch function similar to Windows 7 desktop wallpaper.
