Title:
  backlight doesn't turn on when resuming from suspend

Status in “pm-utils” package in Ubuntu:
  Invalid

Bug description:
  Binary package hint: pm-utils

  Hi guys,
  My Dell Inspiron 8500 doesn't resume properly when suspending. The keyboard 
responds, and it looks as though everything system-wise is intact, except the 
backlight doesn't turn on.

  The only way to get the backlight on again is to do a reboot.

  Backlight control works fine when the screensaver/power management
  triggers it to turn off/on again, but resuming has never worked.

  This laptop used to have an NVidia card (which has since stopped
  working altogether), and I'm pretty sure that resuming worked OK on
  the old video card. It now has an ATI Radeon card.

  I have tried setting radeon.modeset=0 and/or modeset=0 on boot options
  but that locks the machine after a few minutes (as reported here
  https://bugs.launchpad.net/ubuntu/+source/linux/+bug/574848).

  Also tried pm-suspend with various options, as well as playing with
  the quirkdb file, all to no avail.
