마우스는 키보드와 동일한 RF 채널을 사용하여 USB 마이크로 수신기와 통신하므로 논리적으로 보입니다.

RF 키보드가 XF86Forward KeyPress 및 KeyRelease 이벤트를 보내는 것을 방지하는 방법은 무엇입니까?
답변1
자, 요약해보자:
첫 번째 단계는 evtest커널 입력 레이어에서도 이런 일이 발생하는지 확인하고 사용하는 것입니다. 또한 RF 키보드에는 연결된 여러 입력 장치가 있는 경우가 있으므로( evtest검증을 위해 모든 입력 장치에 사용) 실제 키가 아닌 다른 장치에서 나오는 경우 XF86Forward해당 장치를 무시하는 간단한 솔루션이 될 수 있습니다.
실제로 두 개의 장치가 있는 것으로 나타났습니다.
다음 단계는 evtest --grab키+마우스 장치를 사용하여 이벤트가 X 또는 VT에서 처리되지 않도록 evtest로만 전송되도록 하는 것입니다. VT를 사용하면 VT를 전환해도 크롤링이 계속되는지 모르기 때문에 약간 까다로울 수 있습니다. 또한 /dev/input/by-*부팅 시 장치를 올바르게 식별하는 방법도 살펴보세요. 이것이 작동하면 실행해 볼 수 있습니다
evtest --grab /dev/input/... > /dev/null
아니면 시작하는 동안 그런 것.
마우스는 분명히 키보드의 일부이고(또는 동일한 RF 채널을 사용합니까?) 필수이므로 이는 옵션이 아닙니다.
이것이 X에서만 작동한다면 "마우스" 입력 장치를 키보드 대신 마우스로 사용해 볼 수 있습니다. 그러나 VT도 사용하려는 경우 이는 옵션이 아닙니다.
따라서 남은 유일한 일은 XF86Forward마우스 이벤트를 통과시키면서 이벤트를 제거하는 사용자 정의 필터를 작성하는 것입니다. 얼마전에 잠깐 물어본 질문이 있었는데설명하다그것을하는 방법. 여전히 를 사용할 수 있어야 합니다 uinput.
