  display is fully dimmed after resume from suspend

Status in linux package in Ubuntu:
  Won't Fix

Bug description:
  Binary package hint: gnome-power-manager

  When I resume from suspend (while on AC power), the laptop display
  brightness is set to it's lowest level, even when I had the brightness
  turned all the way up before. Interestingly enough, this only seems to
  happen on the first suspend after a reboot. Once I have turned up the
  display brightness again using the function keys, the next
  suspend/resume cycle will work normally (until the next reboot).
  Finally, when I use the function keys to increase the brightness after
  a suspend, I see that the brightness level in the notification bar
  indicates that the brightness is set to the maximum. Only after
  repeated adjustments with the function keys, the indicator 'resets'
  and reflects the true display brightness level. I'm using the
  proprietary nvidia display driver, but I've never had this problem
  before in Jaunty. Also, in case it makes a difference, I've set my
  laptop to suspend on lid closure since that's the way I generally
  suspend the laptop.
