如何为壁纸设置另一个搜索目录？

Question

我将所有文档保存在与 ubuntu 安装不同的驱动器上，并且该驱动器上有一个装满精美壁纸的文件夹。如何让 ubuntu 自动搜索此目录，以便墙纸显示在墙纸更换器对话框中，通过右键单击桌面并选择“更改桌面墙纸”到达？

编辑：我尝试将/usr/share/backgrounds文件夹中的符号链接放入另一个驱动器，但没有用。

* 编辑 - 第二次尝试 - 并立即为所有终端工作道歉 - 希望这应该只是复制和粘贴突出显示的条目*

保存 gnome 壁纸详细信息的文件夹称为 /usr/share/gnome-background-properties/ubuntu-wallpapers.xml

您可以编辑该文件，让墙纸.../墙纸子部分指向您的新文件夹和墙纸文件

下面是从这个论坛条目修改的脚本，它将自动为包含 .png 和 .jpg 文件的文件夹重新生成 ubuntu-wallpapers.xml 文件。

将内容复制并粘贴到名为“ubuntu-wallpaper-generator”的新文本文件中

然后使用语法执行文件

sh ubuntu-wallpaper-generator <path to new wallpaper folder>

这将在您运行此脚本的同一文件夹中生成一个名为 ubuntu-wallpapers.xml 的文件。

安全备份您当前的 xml 文件，即

sudo cp /usr/share/gnome-background-properties/ubuntu-wallpapers.xml /usr/share/gnome-background-properties/ubuntu-wallpapers.xml.backup

新生成的文件中的副本

sudo cp ubuntu-wallpapers.xml /usr/share/gnome-background-properties/ubuntu-wallpapers.xml

这是我提到的脚本文件：

#!/bin/bash
#
# This script will take all wallpapers in a given folder and
# make them available as "default" background in the "Change Background" gui
# frontend in Ubuntu.
