Windows 7, Mint 13(XFCE 포함) 및 Ubuntu 12가 설치된 트리플 부팅 컴퓨터가 있습니다. Windows 7에서만 두 번째 그래픽 카드에 연결된 두 번째 화면이 나타납니다. Mint와 Ubuntu에서 두 번째 화면은 비어 있고 내 디스플레이 속성에서는 화면만 표시됩니다(두 번째 화면은 신호를 수신하지 않기 때문에 절전 모드로 전환됩니다).
둘 다 아래에 나와 있습니다 lshw
(내 마더보드의 온보드 GPU와 함께 표시되지만 사용하고 싶지 않습니다).
두 번째 GPU를 활성화하려면 Mint 또는 Ubuntu에서 특별히 무언가를 "조정"해야 합니까?

두 모니터 모두 # nvidia-xconfig -a
Nvidia 카드를 루트로 사용하는 경우 다음이 수행됩니다.
-a, --enable-all-gpus
Configure an X screen on every GPU in the system.
nvidia-xconfig 매뉴얼 페이지.
편집: nouveau 대신 nvidia의 드라이버를 사용한다고 가정합니다.
