如何为墙纸设置另一个搜索目录？

我将所有文档都与ubuntu安装放在单独的驱动器上，并且在该驱动器上有一个装满漂亮壁纸的文件夹。如何使ubuntu自动搜索此目录，以使墙纸显示在墙纸更换器对话框中，可以通过右键单击桌面并选择“ 更改桌面墙纸”来进行访问？

编辑：我试图将符号链接放在/ usr / share / backgrounds文件夹中到另一个驱动器，但是没有用。

*编辑-第二次尝试-并对所有终端工作立即道歉-希望这应该只是复制并粘贴突出显示的条目*

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

您可以编辑该文件以使其具有墙纸... /墙纸小节，指向您的新文件夹和墙纸文件。

以下是此论坛条目中经过修改的脚本，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。

复制内容并将其粘贴到一个名为“ 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>

这将在与运行此脚本相同的文件夹中生成一个名为ubuntu-wallpapers.xml的文件。

安全地备份您当前的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.

使用CreBS（创建背景幻灯片），您可以为墙纸幻灯片创建XML文件-图像的完整路径存储在XML中，因此无需移动文件。

我遇到了同样的问题，我编写了一个python脚本来编辑可放在中的自定义xml文件/usr/share/gnome-background-properties/my-backgrounds.xml。在GitHub上。

用法示例：

要添加space_galaxy.jpeg和fuzz_dog.pngXML文件：

python my-backgrounds.py -a space_galaxy.jpeg fuzzy_dog.png -n "Cool Galaxy" "Cute Dog"

请注意，默认的xml文件位于/usr/share/gnome-background-properties/my-backgrounds.xml（GNOME监视xml的位置）。要指定备用xml文件，请使用以下-x选项：

python my-backgrounds.py -a space_galaxy.jpeg -x ~/my-backgrounds.xml

要从xml文件中删除条目，请使用以下-r选项：

python my-backgrounds.py -r "Cool Galaxy" fuzzy_dog.png

这适用于GNOME 3.6和Python 3.3

这就是我的方法。

1. 右键单击桌面>更改背景。

2. 在“背景”选项卡上，单击“添加”。

3. 去到该文件夹，并选择所有壁纸，通过点击一个，然后按Ctrl+ A。

现在，它们应该显示在选择器中。我还试图找到一个我曾经使用过的小应用程序，以自动更改墙纸。当我找到它的时候会发帖。

我找到了一个叫Wally的手机，强烈推荐它，但是我记得我没有用过那个。无论如何，您可以通过键入以下内容进行安装

sudo apt-get install wally

在一个终端。

要在选择器中显示墙纸，而不必手动更新文件夹，则必须将它们添加到中/usr/share/backgrounds。

通过在文件夹中创建符号链接，我还能够在选择器中列出墙纸。

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

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