linux mint 螢幕亮度儲存

sudo apt-get install laptop-mode-tools

打開 /etc/laptop-mode/laptop-mode.conf 進行配置，

#
# Enable laptop mode when on AC power.
#
ENABLE_LAPTOP_MODE_ON_AC=1
           

打開 /etc/laptop-mode/conf.d/lcd-brightness.conf

#

# Should laptop mode tools control LCD brightness?

# 設為1，啟用

CONTROL_BRIGHTNESS=1

#

# Commands to execute to set the brightness on your LCD

# “echo 6” 就是要将亮度值6 寫入 BRIGHTNESS_OUTPUT檔案中，亮度值根據自己的情況進行取值。

BATT_BRIGHTNESS_COMMAND="echo 6"

LM_AC_BRIGHTNESS_COMMAND="echo 6"

NOLM_AC_BRIGHTNESS_COMMAND="echo 6"

BRIGHTNESS_OUTPUT="/sys/class/backlight/acpi_video0/brightness"
           

（後面的路徑同樣需要更改才能生效。）

最後重新開機機子即可生效。
