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

[Kamal Mostafa]

Status update:

The upstream maintainers of the i915 driver have recently proposed a new
backlight control mechanism[1], so my "i915bri" patch won't be applied
to the mainline kernel or the official Ubuntu kernels.  The good news is
that the new proposed mechanism is a better approach and will likely fix
the problem for more machines.

I am therefore focusing my efforts on backporting the new proposed
mechanism to Ubuntu Maverick (2.6.35 kernel) and I expect to publish a
Maverick PPA kernel (and the patches) here soon.  This work is not
likely to make it into the Maverick release in October.  I have not yet
evaluated whether or not it will be possible to backport this new
mechanism to Ubuntu Lucid.

Some folks have asked whether I'm planning to port my "i915bri" patch to
Maverick or other 2.6.35-based distros:  Since the new mechanism will
soon be available for Maverick, I do not intend to do so.
