用于在 XFCE4 中切换壁纸的 Bash 脚本

Question

你能帮我写一个 bash 脚本来在 XFCE 下在白天和晚上版本之间切换壁纸吗？我想设置一个 cron 作业来运行它，以便它会根据一天中的时间自动切换。

Answer 1

我写了一个脚本：

#!/bin/bash
xfconf-query -c xfce4-desktop -p /backdrop/screen0/monitor0/workspace0/last-image -s /home/maciek/Pictures/day.jpg

当我从终端运行它时它可以工作。但是当我在 cron 中设置它时它不起作用。我收到一个错误：

Failed to init libxfconf: Using X11 for dbus-daemon autolaunch was disabled at compile time, set your DBUS_SESSION_BUS_ADDRESS instead.
