[Bug 411121] Re: LCD Brightness doesn't change on ASUS U80A laptop

** Description changed:

  I am currently on Ubuntu karmic (development branch) 9.10
  
  When I use the brightness up/down hot-keys on my laptop (Fn+F5/Fn+F6)
  the on-screen display shows up but the level indicator doesn't change
  neither does the LCD brightness.
  
  I searched for solutions to this issue and came across a suggestion to
  add acpi_backlight=vendor to my kernel boot options. This caused the on
  screen display's brightness indicator level to go up and down in sync
  with the hot-keys, but the LCD brightness remains unchanged.
  
  Let me know if I can provide additional information to help with the
  resolution of this issue.
  
  Thanks,
  Akbar
