문제 설명
방금 새 와이드스크린 모니터(Dell Ultrasharp U4919DW)를 구입하여 업무용 노트북 한쪽은 DP에 연결되고 다른 한쪽은 개인 노트북(둘 다 Lenovo ThinkPad)이 USB-C에 연결되는 분할 화면 모드에서 사용합니다. . 모니터에는 키보드와 마우스를 연결한 USB 허브도 내장되어 있습니다. 모니터는 랩톱(하나는 USB-C를 통해 연결되고 다른 하나는 USB 3을 통해 연결됨) 간에 주변 장치를 전환하는 방법을 제공하며 처음에는 작동하기 때문에 이것이 작동한다고 생각합니다(따라서 올바르게 구성되었습니다). 그러나 업무용 노트북(예상대로 작동하는 Windows 10 실행)으로 전환한 후 개인 노트북(Ubuntu 실행)으로 다시 변경하면 키보드나 마우스가 감지되지 않습니다.
최신 버전의 드라이버를 확인했습니다. 그러나 올바른 것이 사용되었는지는 확실하지 않습니다(부록 참조).
출력을 보니 dmesg -w장치의 연결이 끊어졌지만 다시는 연결되지 않은 것으로 나타났습니다.
노트북에서 USB-C 케이블을 뺐다가 다시 꽂으면 USB 허브가 다시 감지되면서 다시 작동합니다.
또한 I cat /dev/bus/usb/003/001(허브의 버스)가 장치를 다시 한 번 감지합니다.
USB-C 케이블을 뽑았다가 다시 꽂을 필요가 없었으면 좋겠습니다. 이렇게 하면 번거롭고 해당 기능을 사용하는 전체 경험이 망가지기 때문입니다. :=)
이 문제에 대해 도움을 주시고 추가 로그나 출력을 요청해 주시기 바랍니다. :)
주목할 만한 점은 비디오와 데이터가 모두 동일한 USB-C 포트를 통해 실행된다는 것입니다(드라이버 문제일 수 있습니까?).
