** Description changed:

  I have a laptop (asus m51sn with Nvidia GeForce 9500M GS)in  dual boot
  system Vista / Ubuntu. When i get off Vista and restart system in Ubuntu
  9.04, after 3-4 seconds from the start, the LCD brightness go down, it's
  almost invisible. I can go up by Fn-F6, but the system doesn't remember
  this brightness, and the problem is the same the next time... I tried
  all the workarounds in Internet, but nothing function for this problem.
  
  p.s.: Today (13 may 2009) i updated my Ubuntu 8.10 (it updated also
  kernel) and now i have the same problem now also in Ubuntu 8.10.
