Title:
  Sony Vaio Backlight

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Lapton Sony Vaio VGN-NR160E
  Ubuntu 7.10 installed, and tryed Ubuntu 8.04 Alpha 4 (LiveCD). Both x86 version.

  Backlight not working.
  Not from FnKeys, or Gnome, or by /sys/class/backlight.

  In /sys/class/backlight, i only have 'acpi_video0', inside:
  * actual_brightness
  * brightness
  * max_brightness
  * subsystem (softlink)
  * uevent

  I tryed echoing to brightness and nothing worked.

  Important note: I don't have '/sys/class/backlight/sony/'
