[Bug 623271] Re: no built-in backlignt in samsung nc10

[Guillaume]

Hi everyone, 
This issue seemed to fix by itself, but by-the-way I installed gnome on my kubuntu, so maybe that's why (I doubt). Maybe it was because of a system update...)

** Tags added: apport-collected

** Description changed:

  Hi, I'm using Kubuntu Lucid Lynx on a Samsung NC10 and I couldn't change
  the backlight for a long time
  
  The only thing that worked for me was using
  setpci -s 00:02.1 F4.B=FF
  replacing FF by a hex value in range 00:FF to adjust brightness
  
  When I run xbacklight it outputs "No outputs have backlight property"
  
  I hope it helps you to fix the bug, and I remain available for more info
