[Bug 1132261] Re: Brightnesst keys do not work on Asus Eee PC X101CH

[Steve Langasek]

The acpi-support script you're modifying is there for setting a
/keyboard/ backlight, not for a display backlight.  So this is a wrong
fix.

The display brightness is meant to be controlled in the kernel, not by
acpi-support.  Reassigning this bug to the kernel.

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

Title:
  Brightnesst keys do not work on Asus Eee PC X101CH

Status in “linux” package in Ubuntu:
  New

Bug description:
  The brightness keys (Fn + F5, Fn + F6) did not work under 12.04. After
  upgrading to 12.10 they still do not work.

  Pressing the brightness keys show the nice display of the brightnesss,
  but displayed brightness is not correct and it does not change up or
  down.

  Changing the brightness manually by writing to /sys/class/backlight
  /psb-bl/brightness works.

  The issue is caused by:
  1. The path to the backlight directory is wrong
  2. The acpi events are not correct - they are not triggered when pressing the brightness keys.
