키보드에서 LCD의 광도를 조정할 때 LCD의 광도 단계를 조정할 수 있는 방법이 있는지 궁금합니다.
전체의 +/- 30%에 불과한 것 같고 꽤 짜증나는 일입니다. 왜냐하면 때때로 그것에 대해 더 많은 제어권을 갖는 것이 유용할 것이기 때문입니다. 예를 들어, 0은 너무 낮지만 30%는 너무 높습니다. 100%로 놔둔 다음 10이 될 때까지 30씩 30씩 줄여 10%에 도달할 수 있지만 여전히 너무 낮습니다.
사운드의 18단계처럼 좀 더 세밀하게 제어하고 싶습니다.
저는 Acer Extensa 5620을 사용하고 있습니다. 제 lshw는 다음과 같습니다.

echo '100' > /sys/class/backlight/psb-bl/brightness
echo `'50' > /sys/class/backlight/psb-bl/brightness
경로만 조정하면 되는데,/sys/class/backlight/your_device/brightness

또는 xbacklight를 설치해 볼 수도 있습니다.
sudo apt-get install xbacklight
xbacklight -inc 10
xbacklight -dec 10
xbacklight -set 60
