私のXorgプログラムは++の使用を切り替えるためにtty1。この時点またはステータス（キーボードの対応するLED照明を含む）が正常に同期することがあります。CtrlAltF[2~6]ttY[2~6]NumLockCapsLock
tty1とtty[2~6]、NumLockまたはを切り替えると、ステータスCapsLockは正常ですがキーボードインジケータは正常に切り替わりません。NumLockキーボードの状態（キーボードの対応するLED照明を含む）を保存して切り替える責任は誰にいるのか知りたいです。CapsLocktty
キーボードイベントを監視するために使用され、evtest例は次のとおりです。
シーン1：
tty1: Num led is on, you can input numbers;
tty2: Num Led is off, you cannot enter numbers;
tty1-->tty2: Num led is on, no number can be input
ctrl+alt+f2, tty1-->tty2, evtest print as follows:
