更改Fedora 17的登录界面背景

进过一些必要的折腾,终于升级到了Fedora17,但是新系统的背景看着很是不爽, 准备换一个,步骤如下:Activities -> Applications -> System Tools -> System Settings -> Background 然后选择自己喜欢的图片,换上去。 但是,换上去一看,只是桌面的背景换了,登录界面的背景还是依旧。 好吧,google,然后找到一篇文章 http://forums.fedoraforum.org/showthread.?t=265990 www.cit.cn 具体的操作步骤如下:

1.open terminal

2. su

3. xhost + // 注意这里是 执行命令 xhost , ’+’ 是xhost 命令的参数 不要敲错

4. sudo -u gdm dbus-launch gnome-control-center

5. Click background and select your background

关于第4个命令的解释如下,有人转载文章的时候会在不理解命令作用的情况下把命令给敲错了, 结果误导人(发帖的人就是被害者),这里有人给出了解释:

sudo lets you execute a command as if you had logged into a different user account. The -u option says which account, in this case the account is gdm dbus-launch is the command that sudo is executing for you in the gdm account gnome-control-center is a parameter you are giving to dbus-launch, it is another program that will be run (also in the gdm account). All together, you type ONE command line just like this:

sudo -u gdm dbus-launch gnome-control-center

注记:貌似锁屏的壁纸还是老壁纸。
