[Bug 568611] Re: Screen brightness control fails on Dell Studio 1558

[Kamal Mostafa]

Status update:

1.  This patch is still pending review upstream.  Thanks for your
continued patience folks.

2.  There was a recent official Lucid kernel update (2.6.32-23 #37), necessitating a rebuild of my "i915 brightness" test kernel.  The latest build for Lucid (based on the current #38 development tree) is available here: http://kernel.ubuntu.com/~kamal/i915bri~3e/latest-lucid/  (source patch in the parent directory). To install this kernel, download the three .deb files and install them using:
    sudo dpkg -i linux*kamal*.deb

After rebooting, verify that "dmesg | grep backlight" yields the following line, signifying that the backlight will be controlled by the i915 driver:
    acpi device:04: registered as backlight/i915
