This issue is now fixed for me with recents kernels on Ubuntu 14.04. I'm
currently using 3.13.0-32-generic.
My amd fglrx driver is 2:13.350.1-0ubuntu2
My intel driver is i915-3.15-3.13-dkms
I have GRUB_CMDLINE_LINUX=video.use_native_backlight=1 into my
/etc/default/grub
Everything seems to work
nb: I'm using the following PPA for the intel driver:

Nicolas Devillers, this is not In Progress as defined in

PPA, and remove your WORKAROUND, is this problem reproducible?
If so, the next step is to test the latest mainline kernel, which is now

Nicolas Devillers, could you please test the latest upstream kernel available

It will allow additional upstream developers to examine the issue. Once you've

Nicolas, ok. Were the acpi_* parameters required to get your backlight
to work in Saucy or address some other issue?

acpi_osi=Linux is not useful actually, and i removed it from my grub config.
acpi_backlight=vendor is required on raring and saucy at least if I want to
be able to manage the backlight. Precise and quantal could be affected as well.
I have to check to see if the problem as always been there.
Nicolas Devillers, from my personal experience, regarding backlight bugs
where one is forced to use acpi_backlight=vendor to enable it, these
reports typically result in upstream making a quirk for the hardware in
order to enable the backlight by default. Hence, the best strategy would

I do believe that it's indeed a regression in the kernel.

However, you still can't control the lightness without it.

I could reproduce with kernel 3.11.0.3.4 and bios A09. Is there any
difference between this kernel and the one provided in your link ?
The bug doesn't seems to happens if I don't set acpi_osi=Linux
acpi_backlight=vendor in my /etc/default/grub. But I wouldn't be able
to modify lightness then.
