Ubuntu를 실행할 때 시스템이 뜨거워지고 주요 처리 작업이 없습니다. 또한 동일한 컴퓨터에서 Windows 10을 실행하고 있는데 Windows에서 실행할 때 결코 뜨거워지지 않으므로 하드웨어 문제를 배제할 수 있습니다. 가장 좋은 추측은 드라이버 문제입니다. AMD Radeon에서 Nvidia GPU를 에뮬레이션하기 위해 Ocelot을 사용하기 위해 시스템을 조작한 후에 문제가 시작되었지만 모든 변경 사항을 취소하고 문제가 지속되기 때문입니다.
아니면 내 시스템이 어떤 그래픽 카드 드라이버를 사용하고 있는지 확인할 수 있는 방법이 있나요?
