Hello,

On my laptop, the display backlight is reported this:

See this screenshot: http://i.imgur.com/mP0H6hX.png =


Now I am confused. Does this mean that my actual display brightness is 4W o=
r 2W and this is only a displaying error of PowerTOP?

If the latter applies, can this be fixed so that PowerTOP only recognises o=
ne display?

I think it is related to the fact that I have two entries in  */sys/class/b=
acklight*

Any help would be appreciated!
