Exactly same problem here with Vaio-VPCY11V9E.
"acpi_video0", "acpi_video1" and "intel_backlight" folders at
/sys/class/backlight and only intel_backlight works when echo'ing values
to brightness with ubuntu 11.10
This is a really PITA, is there any workaround available? It would be a
huge pain-s
Update on Ubuntu 11.10 (Oneiric)
Hi there,
just a quick update on screen brightness issue status, for the Vaio Y series.
The problem seems related to gnome-power-manager & intel 915 driver... Kamal
Mostafa has released a path that should be already present in Ubuntu 11.10.

I have this kind of problem on a Sony VAIO CW2C5E (nVidia 310M). The
only way to control screen backlight is using nvidiabl module from

I can see gnome power monitor correctly interfaces with backlight module
because changing settings in gconf works. Anywa
Dear Francesco,
Today Mr. Tovalds released the new linux kernel. It has some kind of fix for
sony. I'm going to test it this evening after work.
I'll let you know if the issue has changed/resolved. More information can be
found here http://lkml.org/lkml/2010/5/16/89

Dear bas,
I really don't know when an official fix will be available.
I think that the problem is related to the change in the way fn keys are dealt
with: the new trend is to manage the events generated by the key pressure using
gnome power management (or something like that, I don't remember ex
Dear Francesco,
Do you know when there is going to be a proper fix for this issue? It seems
to be present since ubuntu 8.04 and still isn't fixed.
I'm pretty newbe when it comes to launchpad and bug fixing so could really
appreciate your input.
This issue seems to be on lots of notebooks. Dell's,
bas, to remove the patch you have to remove the files that are in the
"script" subfolder of the patch from /etc/acpi/ and the files that are
in the "events" subfolder of the patch from /etc/acpi/events/
Then reboot your laptop and... patch is gone ;-)

I installed the fix on my VPCY11S1E Ubuntu Desktop 10.04 Gnome.
Fn F5 and F6 seem to give me a brightness bar now at the right top of
the screen but is doesn't change the brightness although the bar slides.
How do I uninstall the fix, please. I want to wait for the official
"gnome-power-managemen
Happy that works for both of you too :-)
I have noticed that sometimes (I think if keys are pressed many times
quickly), acpid stops working, and FN keys does not work anymore. No
time to investigate it now.
Cheers, and happy ubuntu! ;-)

Hi Francesco;
Script solved my issue in Ubuntu 9.10. I hope that they have solved the issue
or added your script to upcoming 10.04 version. Thanks for your effort.

I have the same problem with karmic on my sony series Y.
I can get the brightness level and change it with:
sudo setpci -s 00:02.0 F4.B
values are hexadecimal, and vary from 00 to FF.
I have prepared a couple of file to let ACPI catch FN5 and FN6, and a
couple of scripts to increase and decrease

Thank you for taking the time to report this bug and help to improve
Ubuntu.
This is nothing to do with acpi-support, which is a deprecated package
for handling only those ACPI events that aren't handled by the standard
kernel input layer. Reassigning to gnome-power-manager, which I believe
