Answer 1

按照这些说明添加mactelPPA 。

安装软件包applesmc-dkms和hid-dkms.

重启。

sudo vi /usr/local/bin/keyboard-backlight 并添加：

#!/bin/bash
VALUE=$(cat /sys/class/leds/smc::kbd_backlight/brightness)
INCREMENT=32
TOTAL=unset

case $1 in
up)
    TOTAL=`expr $VALUE + $INCREMENT`
    ;;
down)
    TOTAL=`expr $VALUE - $INCREMENT`
    ;;
full)
    TOTAL=255
    ;;
off)
    TOTAL=0
    ;;
esac

if [ $TOTAL == unset ]; then
    echo "Please specify up, down, full, or off"
    exit 1
fi

if [ $TOTAL -gt 255 ]; then TOTAL=255; fi
if [ $TOTAL -lt 0 ]; then TOTAL=0; fi 
echo $TOTAL > /sys/class/leds/smc::kbd_backlight/brightness

紧随其后sudo chmod 755 /usr/local/bin/keyboard-backlight。

sudo visudo 并添加以下行：

your_username_goes_here ALL=NOPASSWD:/usr/local/bin/keyboard-backlight up, /usr/local/bin/keyboard-backlight down

转到System> Preferences> Keyboard Shortcuts。

添加新的快捷方式：

Increase Keyboard Backlight Brightness/sudo keyboard-backlight up和

Decrease Keyboard Backlight Brightness/ sudo keyboard-backlight down.

通过单击键映射框并按下键，将每个键设置为正确的键。
