So it's been another week, and -rc2 is out there....
(b) we had a late change to how ACPI backlight handling is done on
certain machines, and while this kind of thing really shouldn't be
done outside the merge window, I ended up pulling it anyway. But I'd
*really* like to have people test this thing particularly on laptops
with intel-based graphics. It should only matter (and hopefully
improve things) for the newer ones with BIOSes designed for Windows 8,
but hey, the more testing, the better. Backlight handling has been
painful before, so I'm mentioning this explicitly.
