我在 Ubuntu 20.04 上使用 GNOME 3（GNOME Shell）。如果我開啟設定（gnome-control-center）並查看其中的鍵盤佈局，我列出的內容如下：

如果我搜尋應用程式「Ibus keyboards」，我找不到任何結果。然而，從命令列執行 ibus-setup 會得到以下結果：

有趣的是，如果我點擊「Input Method」標籤頁，顯示的列表是空的，儘管我已經設定了 Dvorak 和阿拉伯語鍵盤：

如果我啟動「Language Support」（gnome-language-selector），鍵盤輸入法系統似乎設定為「IBus」：

使用 super +space 切換鍵盤佈局在 Ubuntu 上的其他所有應用程式中都有效，只是 Paratext 不行。當我按下這些按鈕時，頂欄中的鍵盤指示器會如預期般改變。我也可以使用滑鼠透過指示器來切換鍵盤佈局。從我的觀點來看，這裡的錯誤在於 Paratext。
Thanks for the answer!
I’m using GNOME 3 (GNOME Shell) on Ubuntu 20.04. If I open the Settings (gnome-control-center) and look at the keyboard layouts there, this is what I have listed:

If I search for the application “Ibus keyboards”, I don’t get any results. However, running ibus-setup from the command-line gets me this result:

Interestingly, if I click the “Input Method” tab, the list displayed is empty, even though I have both Dvorak and the Arabic keyboard set up:

If I launch “Language Support” (gnome-language-selector), it seems the keyboard input method system is set to “IBus”:

Changing keyboard layouts using super +space works in every other application on Ubuntu, just not Paratext. The keyboard indicator in the top bar changes when I press those buttons, as expected. I can also change the keyboard layout using the indicator using the mouse. From my point of view, the bug here is in Paratext.
