如何为壁纸设置另一个搜索目录？

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，以便壁纸显示在壁纸更换器对话框中，右键单击桌面并选择更改桌面壁纸？

编辑：我尝试在/usr/share/背景文件夹复制到另一个驱动器，但没有效果。

* 编辑 - 第二次尝试 - 并立即为所有终端工作道歉 - 希望这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名为 /usr/share/gnome-background-properties/ubuntu-wallpapers.xml

您可以编辑该文件以使壁纸.../壁纸子部分指向您的新文件夹和壁纸文件

以下是从该论坛修改的脚本入口它将为包含 .png 和 .jpg 文件的文件夹自动重新生成 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

然后使用语法执行该文件

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

这将在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

这是我引用的脚本文件：

#!/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.

使用 CreBS（创建背景幻灯片），您可以创建用于壁纸幻灯片的 XML 文件——图像的完整路径存储在 XML 中，因此无需移动文件。

这是我的做法。

  1. 右键单击桌面>更改背景。

  2. 单击“背景”选项卡上的“添加”。

  3. 去进入文件夹，然后选择所有壁纸，方法是单击其中一个，然后按Ctrl+ A。

它们现在应该显示在选择器中。我还在尝试寻找一个我曾经使用过的小应用程序，用于自动更改壁纸。找到后我会发布。

我找到了一个叫 Wally 的，强烈推荐，但我记得我没有用过它。无论如何，您可以通过输入以下内容来安装它：

sudo apt-get install wally

在终端中。

为了在选择器中显示壁纸，而无需手动更新文件夹，您必须将它们添加到/usr/share/backgrounds。

我还能够通过在文件夹中创建符号链接在选择器中列出壁纸。

$ cd /usr/share/backgrounds
$ ln -s /path/to/wallpapers

这可能会有所帮助，因为每次将壁纸添加到 root 拥有的文件夹中可能并不总是很方便。
