xbacklight No outputs have backlight property

Not xbacklight's fault.

xserver-xorg-video-intel used to offer a few methods for changing the
backlight, defaulting to platform drivers providing
/sys/class/backlight/*. With KMS the i915 driver should probably
provide a fallback if there's no platform driver for backlight.

# Xorg -configure

# cp /root/xorg.conf.new /etc/X11/xorg.conf

Debian sid 沒有 xorg.con

(1) 生成 xorg.org 後修改

# Xorg -configure
# vi /root/xorg.conf.new
# mv /root/xorg.conf.new /etc/X11/xorg.conf
# startx 

(2) 針對單獨設備寫設定檔

# cd /etc/xorg.conf.d/

Reference :
debian sid 现在没有xorg.conf了
