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

[Kamal Mostafa]

I have updated the PPA with a new gnome-power-manager package which
enables the new intel_backlight interface for brightness control
regardless of the presence other backlight interfaces (so the various
acpi_backlight=vendor and *backlight=disable kernel boot parameters
should no longer be required for Gnome desktop users).  Thanks again to
Matthew Garrett for the original intel_backlight patches.

This updated version should enable the brightness controls for a wider
range of Intel GPU based laptops.

  Maverick PPA: https://launchpad.net/~kamalmostafa/+archive/linux-
kamal-mjgbacklight

Upstream status: the patches are still pending review upstream, and have
not yet been applied.
