내 Xorg 프로그램은 ++ 사용 을 전환 하는 데 tty1. 이때 또는 상태(키보드의 해당 LED 조명 포함)가 정상적으로 동기화될 수 있습니다.CtrlAltF[2~6]ttY[2~6]NumLockCapsLock
tty1와 tty[2~6], NumLock또는 사이를 전환하는 경우 CapsLock상태는 정상이지만 키보드 표시등이 정상적으로 전환되지 않습니다. NumLock키보드의 상태(키보드의 해당 LED 조명 포함)를 저장하고 전환하는 책임은 누구에게 있는지 알고 싶습니다 .CapsLocktty
키보드 이벤트를 모니터링 하는 데 사용되며 evtest예는 다음과 같습니다.
장면 1:

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:
