[Bug 573984] Re: Screen brightness can not be adjusted in Lucid with Intel Arrandale graphics

[Ethan Shalev]

I can also confirm this bug on a Gateway NV7915u, running Ubuntu 10.04, kernel 2.6.32.23-generic.
Saghaulor's workaround of manually modifying  /proc/acpi/video/GFX0/DD02/brightness works for me as well.

Is there some logging that can be enabled in order to see what happens
behind the scenes when the Fn + command buttons for brightness are
pressed? So we can see if it is in fact just a permission issue, or
perhaps something more?
