我正在舊桌上型電腦上安裝 Lubuntu，混合了 64 位元和 32 位元架構。我在 64 位元電腦上安裝了 Lubuntu 20.04，喜歡它的 UI，希望在 32 位元電腦上也能安裝 Lubuntu 20.04，因為 32 位元電腦只能安裝 18.04。由於 Lubuntu 從 18.10 開始就為 lxqt 放棄了 LXCE，我想我需要安裝 lxqt。但我無法對 UI 進行任何更改：lightDM GTK+ Greeter 程式據說允許更改主題和圖標，但沒有任何可能的選擇（無論是隨 Lubuntu 安裝的還是我安裝的其他選項）顯示，它始終保持預設主題和圖標。該指令顯示的內容如下lightdm --show-config：
