답변1
귀하가 직면한 문제는 그래픽 드라이버 불일치로 인한 것일 수도 있고 필요할 수도 있다고 생각합니다.
부팅에 Bumblebee(NVIDIA의 Optimus 기술용)를 사용하고 있는 것 같습니다.
이 작업에 대한 위험은 귀하의 책임 하에 시도하십시오.
먼저 자신이 가지고 있는 그래픽 카드가 무엇인지 알아보세요.
lspci | grep VGA
이는 "NVIDIA Corporation GF116M [GeForce GT 550M] (rev a1)"을 사용하고 있으므로 NVIDIA입니다.
그런 다음 xorg-edgers PPA에서 설치하십시오. 최신 버전을 사용하세요.
sudo add-apt-repository ppa:xorg-edgers/ppa
sudo apt-get update
sudo apt-cache search nvidia
Find the latest one (at time of this writing was 352)
sudo apt-get install nvidia-352
sudo apt-get install nvidia-352-updates
그 과정에서 Noveau를 제거하고 xorg-edgers PPA에서 NVIDIA 드라이버를 설치했습니다. 그 후 obs는 꽤 잘 출시되었습니다.
다만, 화면이 가끔 멈춤 현상이 나타나는데, 이를 토대로 범블비를 활용해 어떤 변화가 있는지 살펴보려고 합니다.
행운을 빌어요
참고: NVIDIA에서 직접 NVIDIA 드라이버를 설치하지 못했습니다.
