           Summary: Brightness is increased when set too low
    Classification: openSUSE
           Product: openSUSE 11.2
           Version: RC 2
          Platform: x86-64
        OS/Version: openSUSE 11.2

Brightness control works on my Gateway Tablet PC, but only if you set
brightness >=13%. If you set it lower, say 12%, the brightness appears as you
set ~30% (brighter than if you set 13%). No matter how much lower you set it,
you always get the same level.

I explain better with a table:

you set | you get
--------+--------
   0%   |  ~30%  
   5%   |  ~30%  
  12%   |  ~30%  
--------+--------
  13%   |   13%  
  50%   |   50%  
 100%   |  100%  

If this was done to prevent user from choosing 0%, you should set the internal
brightness to 13% when user selects something <13%. In this case, I would also
suggest to lower this bound, to say 5%, to allow extreme power saving on
laptops.

Reproducible: Always
