[Bug 483062] Re: [gm45] brightness control previously work after xrandr invocation now does not

[Robert Hooker]

That's because there is no native backlight support from i915 for XRANDR
to use when KMS is in use, and KMS wasn't in use in jaunty by default.
Discussions are going on upstream about how to implement it [1] but it
will not be available until the lucid+1 timeframe at the earliest, and
you can boot with i915.modeset=0 to restore the old functionality if
it's absolutely required.
