ubuntu 26.04 + 595.71.05 + CUDA 13.2

1080 ti 연결했더니 lspci 에서는 보이는데, nvidia-smi 에서 안뜬다. 

드라이버 올라가면서 사용불가가 된건지, 아니면 cuda 버전 때문인진 모르겠다.

 

ubuntu-drivers autoinstall 대신 install만 치면 자동으로 설치된다.

gpt에 의하면 1080ti가 인식 안되는게 nova_core로 인해서 정상적으로 인식을 못한거 같다는데, 또 꼽기 귀찮은디..

아무튼 독점 드라이버가 아니라 오픈소스로 개발된 커널 드라이버라서 안되는걸까?

최신이라고 해도 hopper + pascal 이렇게 조합은 불가능하려나?

NVIDIA Grace Hopper 또는 NVIDIA Blackwell과 같은 최첨단 플랫폼의 경우 오픈 소스 GPU 커널 모듈을 사용해야 합니다. 독점 드라이버는 이러한 플랫폼에서 지원되지 않습니다. Turing, Ampere, Ada Lovelace 또는 Hopper 아키텍처의 최신 GPU의 경우 NVIDIA는 오픈 소스 GPU 커널 모듈로 전환할 것을 권장합니다. Maxwell, Pascal 또는 Volta 아키텍처의 이전 GPU의 경우 오픈 소스 GPU 커널 모듈이 해당 플랫폼과 호환되지 않습니다. NVIDIA 독점 드라이버를 계속 사용하세요. 동일한 시스템에 구형 및 최신 GPU를 혼합하여 배포하는 경우, 계속해서 독점 드라이버를 사용하세요.
