From bug #503577, on a Dell mini 10, 'apci_backlight=vendor' kernel parameter
seems to make it work.
acpi_backlight=[HW,ACPI]
acpi_backlight=vendor
acpi_backlight=video
If set to vendor, prefer vendor specific driver
(e.g. thinkpad_acpi, sony_acpi, etc.) instead
of the ACPI video.ko
Sorry for the noise, but are you sure this is an upstream kernel issue?
Comment #52 says the keys work fine with the mainline kernels 2.6.32. So
either this is ubuntu kernel-specific or it has been solved upstream
already (in which case ubuntu would need to backport a fix or upgrade
the kernel
Oooh, ahh. Ignore my previous comment #61. I see that you only changed
the upstream linux aspect as invalid, and not the whole bug. I am fine
with that change, of course. Sorry for even more noise.

I found a workaround here:
http://bbs.archlinux.org/viewtopic.php?id=73889
I can change the brightness with setpci -s 00:02.0 F4.B=FF where FF is a
brightest mode and 00:02.0 is from lspci | grep VGA.
Now I can set the brightness using setpci, how can I make acpi to use
this command?

Thank you for bringing this bug to our attention. However, a paper cut
should be a small usability issue, in the default Ubuntu 9.10 install,
that affects many people and is quick and easy to fix. So this bug can't
be addressed as part of this project.

Same problem on Acer Aspire 5738. And brightness adjustment didn't work
on Jaunty, either.
Besides, the screen never seems to reach its full brightness and it
flickers sometimes.

I have the same problem on my lenovo 3000 v200. I think perhaps it has

Before upgrading to Karmic I tried installing the latest kernel and

KMS, i could use the fn keys again just fine.

I don't know if this information helps, but here in my Lenovo Y430 the
keys work fine until just a bit after GDM starts. Maybe it's a module or
daemon loaded by Upstart. I think it's worth to check it.

On Lenovo 3000 N200, I have to revoke the experiences of Ualpa and mientefuego,
that the brightness-keys would work until (or short after) loading GDM.
In my case, the brightness-keys stop working immediately when passing grub2 in
the boot-process.

I've just tried the brightness function keys on my 3000 N200, and they

as the grub menu countdown finishes and grub starts work.
