참고: 질문 하단에 제가 생각할 수 있는 모든 시스템 세부정보를 포함시켰습니다.
몇 주 동안 저는 노트북을 외부 화면에 도킹할 때 시스템이 느려지는 증상을 겪었습니다. 이동하는 창이 끊기며, 양쪽 화면의 비디오가 프레임을 떨어뜨리고 정지하며, 화면 찢어짐이 매우 심각합니다(이것은 붉은 청어일 수 있으며 알려진 문제라고 읽었습니다).
도킹 시 설정: 노트북 화면 비활성화, 세로 방향의 4k 모니터 1개, 가로 방향의 4k 모니터 1개.
저는 glmark2를 3번 설치하고 실행했습니다. 한 번은 도크가 연결되지 않은 노트북 화면에서, 한 번은 설명된 화면에서, 한 번은 화면 모두 가로 모드에서 실행했습니다. 전체 출력은 다음과 같지만 분수는 ~2000, ~250, ~2000입니다.
문제 해결 기술이 거의 끝나가고 있지만 이러한 증상과 일치하는 문제에 대한 좋은 참조를 찾을 수 없습니다. 두 화면이 모두 가로 모드일 때 glmark2 탐색경로 증상이 나타나지 않기 때문에 도크 문제처럼 느껴지지 않지만 가능한 도크 문제로 문제 범위를 좁힐 수 있는 제안을 받고 싶습니다.
안정적인 구성을 시도하려면 명령 출력 요청이나 제안을 수락하세요. 다음에 어디로 가야할지 모르겠고, 비디오 드라이버 블로그 항목, 배포판 버그 목록, 커널 버그 목록 등을 검색했지만 소용이 없었습니다. 시스템 속도가 느려지지 않고 두 번째 화면을 회전할 수 있기를 원합니다.
빠른 참고 사항: glmark 테스트는 기본적으로 Intel HD 630 디스플레이 드라이버를 대상으로 한다는 점을 알 수 있습니다. "env DRI_PRIME=1 glmark2"로 칩을 실행하여 별도의 Vega M을 강제 실행하면 유사한 점수 결과가 생성되지만 수직 방향 디스플레이에서는 차이가 있습니다.
