Debian 10 [Buster]: HDMI 입력이 감지되지 않음

OS: GNOME 3.30.2 on Debian GNU/Linux 10 (64-bit)

노트북의 HDMI 포트에서 출력이 없습니다. 모니터에 "입력이 감지되지 않았습니다"라고 표시됩니다. 이전에 Kubuntu를 설치했고 그 전에 Windows 10을 설치했는데 둘 다 잘 작동했습니다. 이는 하드웨어 문제가 아니라는 것을 의미합니다.

나는 시도했다:

• "ARandR" 패키지를 사용하여 새 모니터를 검색합니다.

• 다른 모니터와 HDMI 케이블을 연결합니다.

• 모니터를 연결한 상태에서 기기를 시작합니다.
