GRUB를 사용하여 Windows 10(문제 없음)과 함께 Ubuntu를 실행하는 두 개의 GPU(Intel HD4600, Nvidia GTX850M)가 있는 노트북이 있습니다.

설치했지만 나쁜 경험으로 인해 nvidia-355설치하지 않았습니다 bumblebee(작동하지 못하거나 설치가 중단되었습니다).

문제:

그래픽 부하가 높을 때 디스플레이/그래픽 관련 문제가 발생하고 부팅 메시지의 일부가 잠시 깜박인 후 다시 로그인 화면으로 돌아갑니다.

두 GPU를 모두 나열하는 lscpi 출력

이번 주말 에 장난을 쳤는데 xorg.conf이전에는 다음과 같았습니다.

변경하려는 모든 내용은 다음 부팅이나 그래픽 로그인 시 덮어쓰여졌습니다. 부팅 옵션을
추가 하고 Nvidia X 서버 설정을 통해 이 구성을 생성했습니다.nogpumanager

어떻게 든 부팅시 덮어 쓰지 않았습니다.

원활하지 않은 경험을 하는 원인은 무엇이며 어떻게 해결합니까?

그래픽 드라이버, 드라이버 구성 및 GUI 부팅을 방해할 수 있는 사항은 내 강점이 아니므로 문제가 발생할 경우 복구할 수 있는 것만 시도하려고 합니다.

내가 아는데 것을:

  • 플래그 없이 부팅하면 nogpumanagerxorg.conf가 기본값으로 복원됩니다.
  • nouveau 대신 nvidia 드라이버를 사용하면 gui로 부팅되지 않습니다.

편집하다:

문제를 재현하려고 시도했지만 다른 문제가 발생했습니다. 몇 가지 프로그램을 열었을 때 GUI가 Alt-Tab에서 멈춰서 칠흑같이 어두워졌습니다. 프로그램의 소리는 멈추지 않았고 TTY에 액세스할 수 있었습니다. GUI로 돌아가려면 lightdm을 다시 시작해야 했습니다.
