Question

你可以帮我编写一个bash脚本，用于在XFCE下的日夜版本之间切换壁纸吗？我想设置一个运行它的cron作业，以便它会根据一天中的时间自动切换。

Answer 1

我写了一个剧本：

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

从终端运行时它可以正常工作。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.
