[ I guess the bug's subject is wrong, should be

  "xbacklight -inc doesn't work, xbacklight -dec and xbacklight -set work"

]

On my Samsung nc10 using awesome as windowmanager -inc does not work, -dec and
-set do.

Hi!

I had the same problem at my N140. Try to change the percent value to
some higher / lower values. At my netbook, i'm using:

xbacklight -dec 15
xbacklight -inc 15

If this is still an issue, please provide the output of 'xrandr
--verbose'.

Thanks,
