[Bug 832483] Re: Toshiba R835-P56X - screen brightness control does not work after suspend/resume

[Steve Langasek]

acpid and acpi-support aren't supposed to be involved in handling such
events.  Reassigning to the kernel.

** Package changed: acpi-support (Ubuntu) => linux (Ubuntu)

Title:
  Toshiba R835-P56X - screen brightness control does not work after
  suspend/resume

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Toshiba R835-P56X - screen brightness control does not work after
  suspend/resume.  It works just fine before suspend/resume.  After
  suspend/resume, the dbus (or whatever) indicator shows the brightness
  slider-bar changing, but the screen brightness doesn't actually
  change.

  Restarting acpid or acpi-support doesn't make any difference.  Only
  workaround that I've found so far is to reboot the machine.

  I'll be happy to perform any tests that you all can suggest, as well
  as provide more/deeper debugging information.  I've been a Linux
  user/sysadmin since 1998, and I'm proficient in
  programming/development -- but I'm mostly unfamiliar with the acpi and
  Linux's implementation of it.
