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.
