Nelson Álvarez Sáez, 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

Please note, given that the information from the prior release is
already available, doing this on a release prior to the development one
would not be helpful.

If reproducible, could you also 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-rc7

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:
  Screen brightness set to minimum

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  I wanted to try Natty from an USB stick. The purple screen at the
  beginning displayed correctly, then the laptop screen went blank. Some
  seconds later I heard the startup sound, but the screen was still
  black. Holding the laptop in an angle, I can notice there is something
  being displayed on the screen, such as the panel, and I can even open
  dialog boxes by clicking at random, but they look only as faint darker
  spots on the screen. It seems to me that the screen brightness is set
  to minimum, but the brightness controls won't work. The problem
  persists in Oneiric Beta 2.

  No display problems with Maverick.

  I have a PackardBell Butterfly XS

  I made lspci | grep VGA in the terminal and got this:
  00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07)
