Sorry for my mistake! The bug is still issue me... But this workaround
works for me:
GRUB_CMDLINE_LINUX_DEFAULT=“quiet splash acpi_osi='Linux'"
I apologize for the inconvenience.
Regards,
Ferenc

gunbladeiv, this bug was reported a while ago and there hasn't been any
activity in it recently. We were wondering if this is still an issue? If
so, could you please test for this with the latest development release
of Ubuntu? ISO images are available from http://cdimage.ubuntu.com

Same problem in 13.04. Setting /etc/default/grub and change the cmdline
to:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi=Linux"
Then update-initramfs makes Fn L/R buttons work. Brightness applet still
doesn't work, but at least it remembers the Fn keys work.
uname: Linux sean-Aspire-4736Z 3
in 12.10 on eMachines E525 - the problem remains

Have you looked at bug 518002? Particularly at workaround 2 (setpci -s

Hi,
I have an Acer Aspire 5738 with exactly the same problem.

I changed from "vendor" to "native" and the notification now shows when
pressing FN+F6 and FN+F7, bit screen brightness does not change. Does anybody
knows the magic word (if any)?

Hi all...
The addition of "nomodeset acpi_backlight=vendor" to GRUB_CMDLINE_LINUX in
/etc/default/grub (with subsequent update-grub) used to work ok in my NB
(Toshiba Satellite Pro T110 009007) with 9.10 and 10.04 beta1. After installing
10.04 beta 2, it no longer works. Not even the notificatio
No problem, thanks a lot for the help. I did presume /etc/default/grub
was the file to work with, but it didn't help me whatsoever. I had to
settle with GRUB_CMDLINE_LINUX="nomodeset acpi_backlight=vendor" and
lose the welcome screen.

I'm very sorry. I made a mistake writing the description as I wrote how to do
it in earlier versions of Ubuntu. The only way to enable it is editing
/etc/default/grub as that is the file responsible for default boot options.
"Linux" and Linux mean exactly the same. It's just tidier.
One more time
Pioterek, thanks a lot for your time. Unfortunately, the file
/boot/grub/menu.lst doesn't seem to exist on my Ubuntu 10.04 (Lucid
Lynx).
However, I did manage to enable brightness controll by editing
/etc/default/grub as described in:
https://bugs.launchpad.net/ubuntu/+source/acpid/+bug/392948/co
Томица, you have to open up terminal and:
1. sudo gedit /boot/grub/menu.lst
2. Find there a line which starts with GRUB_CMDLINE_LINUX_DEFAULT and add
before the ending quotation mark acpi_osi=Linux
3. save the file
4. sudo update-grub
And that's it. It should work, when you'll restart computer.

Piotrek, I also have Ubuntu 10.04 on Aspire 5738z, but I'm a complete
beginner and I couldn't quite understand what should I do with
acpi_osi="Linux" ? Can you please help me out, where should I type this
line? Thank you in advance.

Hey! Linux must be written between quotation marks, not between apostrophes.
acpi_osi="Linux" does work.
