나는 이 세상에 처음이다. 따라서 F5/ F6기능 키는 기본적으로 작동하지 않습니다. grub 변경에 대한 몇 가지 온라인 솔루션을 시도했지만 운이 없었습니다. 자체가 아니라 /sys/class/backlight/
에서 파일을 찾지 못했습니다 intel_backlight

올바른 백라이트 옵션을 찾을 때까지 감마 값을 조정할 수 있습니다 xrandr
. xrandr --query
예를 들어 두 번째 행의 첫 번째 항목에서 모니터 이름을 가져온 eDP
다음 밝기를 설정하는 데 사용됩니다 .
xrandr --output eDP --bightness 0.5
값의 범위는 0("검은색 화면")부터 1("정상"), 255("왜 이것을 하는가?")까지입니다.

알고 보니 그래픽 드라이버를 인식하려면 커널을 5.8로 업데이트해야 했습니다. 이것으로 문제가 해결됩니다. 귀하의 제안에 감사드립니다.
