ubuntu系統(華碩筆記本)螢幕亮度用Fn控制的調節設定，ubuntufn
親測配置:

系統:Linux lite 3.2 x86_64(Ubuntu其他版本可參考修改)

筆記本:華碩(asus)1201N

達到的效果:

可以正常使用Fn+F5調暗,Fn+F6調亮.

設定步驟:

• 修改/etc/default/目錄下檔案grub

將15~16行內容:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"GRUB_CMDLINE_LINUX=""

修改為如下內容

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi=Linux"GRUB_CMDLINE_LINUX="acpi_backlight=asus"

備忘:上面asus是華碩(我的筆記本電腦是華碩的品牌)

• 在終端輸入命令

sudo update-grub

• 重啟電腦

附:修改後的grub檔案:
