Title:
  [Samsung NP-R540-JS04HK] Regulation of the brightness  don't work on
  ubuntu 11.04

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  I write in order to expose to me my problem to you, than I do not succeed to resolve in no way: the regulation of the brightness of the monitor of mine notebook Samsung R540 JS04.
  When I used Ubuntu 10,10 I succeeded in regulating the brightness of the screen, even if not with the Fn keys, with the predefined applet of Gnome. Now that I have installed Ubuntu 11.04 I more do not succeed to carry out no regulation.
  When the PC is fed solo from the battery the screen winds down the brightness automatically and remains so. If the food with the net electrical worker the brightness salt.
   Therefore I suppose that such regulation can be made even if I do not know like, otherwise the brightness would not go up inserting the feeder.
