Title:
  [Samsung QX410] Lid close events not recognized

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  Under Ubuntu 11.04 with kernel 2.6.38-11, closing the lid on this
  laptop would change the value in /proc/acpi/button/lid/LID0/state from
  open to closed, thus triggering, for instance, a suspend event.

  Under Ubuntu 11.10 with kernel 3.0.0-12, closing the lid doesn't
  change the value, and thus the kernel doesn't notice when the lid gets
  closed. The screen does turn off though (and back on on lid open); but
  this is only the screen backlight.

  TEST CASE:
  - Install Ubuntu 11.10 on a Samsung QX410
  - Close the lid when the system is running.

  Expected result:
  - As per default configuration, the system should suspend.

  Actual result:
  - System remains fully powered, only the screen backlight turns off.

  I also ran fwts lid and it was unable to detect the lid close events
  (as the kernel sends nothing).

  Note that this constitutes a regression as the problem was not present
  on kernel 2.6.38-11.

  I'm willing to run any diagnostics required to further pinpoint this
  problem. I'll also try a mainline kernel when I get some time.

  Thanks!
