Ubuntu系统(华硕笔记本)屏幕亮度用Fn控制的调节设

系统:Linux Lite 3.2 x86_64(Ubuntu其他版本可参考修改)

笔记本:华硕(asus)1201N

Linux Lite 3.2发布下载,基于Ubuntu 16.04.1  见

达到的效果:

可以正常使用Fn+F5调暗,Fn+F6调亮.

设置步骤:

修改/etc/default/目录下文件grub

将15~16行内容:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

GRUB_CMDLINE_LINUX=""

 

修改为如下内容

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi=Linux"

GRUB_CMDLINE_LINUX="acpi_backlight=asus"

 

备注:上面asus是华硕(我的笔记本电脑是华硕的品牌)

在终端输入命令

sudo update-grub

 

重启电脑

# /boot/grub/grub.cfg.
