Dan, this bug was reported a while ago and there hasn't been any
activity in it recently. We were wondering if this is still an issue? If
so, could you please test for this with the latest development release
of Ubuntu? ISO images are available from http://cdimage.ubuntu.com
/daily-live/current/ .

If it remains an issue, could you please run the following command in
the development release from a Terminal
(Applications->Accessories->Terminal), as it will automatically gather
and attach updated debug information to this report:

apport-collect -p linux <replace-with-bug-number>

Title:
  Backlight out for exactly 10 seconds on boot with Acer D255E

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Backlight goes out for exactly 10 seconds before returning while
  booting with an Acer AOD255E netbook. This is a backlight issue, as I
  can shine a flashlight at the screen and still see boot text scrolling
  (after removing splash and quiet).

  With "acpi=off" appended to the kernel line, this no longer occurs (Fn
  key backlight controls still work with this appended). With every
  other acpi option I have tried, this still occurs though. This
  includes "acpi_backlight" and "acpi_display_output". With
  "acpi_backlight=vendor" the entry in /sys/class/backlight changes from
  acpi_video0 to acer_wmi, but backlight still goes out.

  Otherwise backlight works correctly. System info is attached.
