有的电脑确实无效，应该还是缺少驱动造成的。

我的可以调节，但是fn不好用

手动修改下 /sys/class/backlight/intel_backlight/brightness 的数值即可调节亮度，写的了个简单脚本用来调节亮度(leo需改成自己的用户名)，

# !/bin/sh
# modify_brightness.sh

echo "The current hightest brightness:"
cat /sys/class/backlight/intel_backlight/brightness

sudo chown leo /sys/class/backlight/intel_backlight/brightness
sudo chgrp leo /sys/class/backlight/intel_backlight/brightness
echo
echo "Do you want change the default brightness(Max=4296) ?"
echo "lease input the new value: "
read new_bri
sudo echo $new_bri > /sys/class/backlight/intel_backlight/brightness
echo
echo "Brightness has already been changed..."
echo
echo "New brightness: "
cat /sys/class/backlight/intel_backlight/brightness
echo "Done..."

sudo chown root /sys/class/backlight/intel_backlight/brightness
sudo chgrp root /sys/class/backlight/intel_backlight/brightness
sudo chmod 644 /sys/class/backlight/intel_backlight/brightness
exit

那FN快捷键不好用怎么办，

这个也是驱动控制的
