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

misko, 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 following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the daily folder, but the one all the way at the bottom. 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-v3.11-rc5

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:
  Brightness-Troubles with Acer Travelmate 8481TG

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  On an Acer Travelmate 8481TG using the default-config, the screen's
  brightness can't be controlled (with Fn+cursor-key), altought the
  event is recognized (and displayed in a popup in the upper right
  corner of the screen).

  With the kernel-parameter "acpi_backlight=vendor" the brightness-
  control works (with Function-Key), but then another problem arises:
  When the screen is switched of via DPMS (automatically after 10
  minutes, or manually with "xset dpms force off"), it can't be
  reactivated by moving the mouse or pressing any key (as without
  acpi_backlight=vendor), instead the screen has to be reactivated with
  the brightnes-control-keys (which does not work while the screen is
  locked).
