[ltp] xbacklight: No outputs have backlight property

[Qiuye Wang]

Hello list,

I was trying to turn the brightness of my (native) screen on T60 with
xbacklight. But I kept getting the message ``No outputs have backlight
property''. I've changed the driver of my x1400 to vesa and fglrx, but
xbacklight behaves the same. I'm wondering if this is a driver or
Thinkpad or xbacklight issue. 

Anybody has an idea? Thank you.
