在运行Ubuntu 13.10的我的11.2 MacBook Pro上,使用此命令获得了令人满意的结果,这使启动任务使启动登录屏幕时它们变暗:
sudo cat > /etc/init/mbp-save-battery.conf << EOF
description "Lower screen and keyboard backlight brightness on boot"
task
start on login-session-start
script
# lower screen brightness
echo "35" > /sys/class/backlight/acpi_video0/brightness
# Somebody else turns on the keyboard backlight
# Wait for them before turning it off.
sleep 1
echo "0" > /sys/class/leds/smc\:\:kbd_backlight/brightness
end script
EOF
键盘背光控制的睡眠并不理想,但是每次都对我有用。
