圖形使用者介面程式
可以透過「圖形使用者介面程式」，來更改「桌面圖片」。
在桌面，按下「滑鼠右鍵」，就會出現一個選單，選擇「Change Background…」。
就會出現設定更改「桌面圖片」的操作介面。
也就是「Settings / Background」。
gnome-control-center background
指令操作
也可以透過「gsettings」這個指令，來更改「桌面圖片」。
gsettings set org.gnome.desktop.background picture-uri 'file:///usr/share/backgrounds/Blue_flower_by_Elena_Stravoravdi.jpg'
在測試的過程中發現，若使用「佈景主題」的「暗色系」，則要執行下面指令
gsettings set org.gnome.desktop.background picture-uri-dark 'file:///usr/share/backgrounds/Blue_flower_by_Elena_Stravoravdi.jpg'
當設定「
gsettings set org.gnome.desktop.interface color-scheme 'prefer-dark'」，會優先採用「佈景主題」的「暗色系」，請參考「theme / color-scheme」
相關應用：「wallpaper-select-gnome」
小技巧
切換顯示桌面的按鍵組合是「Win + d」。
執行
gsettings list-recursively | grep '<Super>d'
顯示
org.gnome.desktop.wm.keybindings show-desktop ['<Primary><Super>d', '<Primary><Alt>d', '<Super>d']
執行
gsettings get org.gnome.desktop.wm.keybindings show-desktop
顯示
['<Primary><Super>d', '<Primary><Alt>d', '<Super>d']
