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.
設置步驟:
- 修改/etc/default/目錄下文件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"
備註: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
