YannUbuntu, 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:
  [regression] Acer Aspire 5736z needs nomodeset or acpi_osi=Linux

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Reported by pescadou999 on the ubuntu-fr forum ( http://forum.ubuntu-
  fr.org/viewtopic.php?pid=10790101#p10790101 ).

  Acer Aspire 5736z
  There was no problem with default settings in 10.04.

  Since 12.04 (tested with default kernel, and with 3.6.0 mainline):
  - default settings: very low brightness (it is very difficult to see the login screen appearing). The Fn+brightness keys have no effect.
  - with 'nomodeset' on 12.04: brightness is ok, but the screen resolution is bad (image is distorted)
  - with 'acpi_osi=Linux': brightness is low at first, but Fn+brightness allow to increase it successfully. Image is not distorted.
