X11
鍵盤事件未到達 X 伺服器
我在沒有 GUI 的 Raspbian 10 (buster) 上。然後我安裝了 X 伺服器並做了一個
startx，但隨後按下鍵盤上的鍵對螢幕沒有影響，如圖所示。當我插入鍵盤時，以下內容被寫入

如果我
xinit改為這樣做，也會發生同樣的事情。我安裝了以下相關軟體包：

showkey。有任何想法嗎？
我認為您的鍵盤可以工作，但 X 應用程序可能沒有焦點。試試這個。在 ~/.xinitrc 添加一行（如果文件不存在則創建文件）
xterm &這告訴 startx 在啟動時執行該命令。嘗試在那裡輸入。如果它不起作用並且您有滑鼠，請點擊 xterm 視窗並再次鍵入。如果您沒有滑鼠，請嘗試使用 Alt-tab 並查看是否可以鍵入。
