我需要通过终端更改背景壁纸。因此我在终端中输入了以下行:
gsettings get org.gnome.desktop.background picture-uri 'file:///appdev/wallpaper.jpg'
输出为:
Usage: gsettings [--schemadir SCHEMADIR] get SCHEMA[:PATH] KEY
Get the value of KEY
Arguments: SCHEMADIR A directory to search for additional schemas
SCHEMA The name of the schema PATH The path, for relocatable schemas KEY The key within the schema
如下所示使用也set
不起作用:
gsettings set org.gnome.desktop.background picture-uri 'file:///appdev/wallpaper.jpg'
我该如何解决这个问题?
