Macbook의 화면 밝기에 문제가 있습니다.
(재)부팅 후에는 제대로 작동하지만 덮개를 닫았다가 다시 연 후에는 화면이 매우 밝거나(밝기 키를 사용하여 조정한 경우 처음 3개의 밝기 설정에서) 완전히 검은색(처음 3개의 밝기 설정에서는 아무 것도 없음)이 설정됩니다. ).
인텔 그래픽 카드가 있습니다.
나는 이 게시물을 안다Linux Debian에서 MacBook Air의 화면 밝기는 여전히 높게 유지됩니다., 그러나 거기에 제안된 솔루션은 전혀 작동하지 않는 것 같습니다. 내 경우에는 제안된 커널 옵션을 사용하여 어떤 일이 발생해야 하는지가 기본 동작인 것 같습니다. (이 문제에 영향을 미치는 커널 업데이트가 있는 것 같습니다.)
바로 실행 해서 systemctl suspend노트북을 깨웠더니 문제 동작이 발생하지 않더군요. 그러나 때로는 오랜 시간 동안 검은색 화면에 머물러 있기 때문에 단순히 일시 중지 모드(최대 절전 모드?)만 수행하는 것이 아니라 문제 동작이 시작되고 재부팅할 때까지 멈추지 않을 수도 있습니다.
(편집: 추가 정보)
/sys/class/backlight/intel_backlight에 가서 값을 "밝기"로 표시해 보았습니다.
- 2228 이상을 사용하면 최대 밝기를 얻을 수 있는 것 같습니다.
- 2227을 사용하면 이상한 깜박임 효과가 나타납니다.
- 2226을 사용하면 깜박임 효과를 낼 수도 있지만 훨씬 더 어둡습니다.
- 마지막으로 2225도 이하의 온도에서는 완전한 어둠이 찾아옵니다.
내 옵션은 무엇입니까?
편집: dmesg에서 다음과 같은 의심스러운 메시지를 발견했습니다.
편집 2: 이 메시지는 관련이 없을 수 있습니다. 현재 동작에는 해당 메시지가 없습니다. 또한 백포트된 커널 버전(내 생각에는 4.1)을 설치했지만 Wi-Fi가 작동하지 않았기 때문에 3.16으로 다시 부팅했습니다.
