듀얼 GPU xorg.conf는 하나의 GPU에서 XScreen을 무시하고 xrandr을 사용합니다.

듀얼 GPU X11은 xorg를 사용하여 작업 부하와 화면을 분리합니다. 2개의 GPU 3개의 스크린/모니터. 원래

GPU 0 => XScreen 0.0 => 모니터 0(왼쪽)

GPU 1 => XScreen 0.1 => 모니터 1(가운데)

GPU 0 => XScreen 0.2 => 모니터 2(오른쪽)

이것을 설정했을 때 시스템은 2개의 XScreen(각 GPU당 하나씩)만 인식한 다음 측면 화면을 함께 클러스터링하여 레이아웃을 망쳤습니다.

왜 이런 일이 발생하는지에 대한 의견을 주시면 감사하겠습니다.
