["Christopher M. Penalver" <christopher.m.penalver@xxxxxxxxx>]

Terry Jones, 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>

Also, could you please test the latest upstream kernel available (not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.13-rc1

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results. Thank you for your
understanding.

Title:
  8086:2a42 emachine e725 boots to valid display with no backlight

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Booting to a black screen, however a flashlight shows a faint login window.  I can login, hear the startup sound, but still a black screen.
  Again a flashlight on the screen shows a faint desktop.  I am assuming the backlight on the laptop is not responding.  Pressing the function key and brightness adjustment keys does nothing.

  As a work around, adding the boot paramater acip_osi=Linux to Grub on
  startup allows me to have a screen,  However, the function dim keys
  make it brighter while the function brighter keys make the screen
  dimmer.
