I upgraded my Sony Vaio VPCYA1V9E from Wheezy to Jessie.
It now has these versions of packages:
xserver-xorg-video-intel2:2.21.15-2+b2 amd64
linux-image-3.16.0-4-amd64 3.16.7-ckt25-1 amd64
As a test, I commented out all of /etc/X11/xorg.conf.
/var/log/Xorg.0.log then showed:
[166061.586]
package xserver-xorg-video-intel
tags 651741 - fixed-upstream
found 651741 xserver-xorg-video-intel/2:2.19.0-6

The upstream developers of xf86-video-intel denied my request to
blacklist the faulty VAIO ACPI implementation. They said Linux
should be patched instead. I have not yet reported
It seems adding only one kernel parameter acpi_backlight=vendor also
works on my G360 now. But, both methods of adding kernel parameters will
stop work occasionly.
The detail of my case see:
Bug 44809 - [Arrandale backlight] Brightness via RANDR has no effect on
Sony VAIO VPCYA1V9E:
Added acpi_backlight=vendor acpi_osi=linux video.brightness_switch_enabled=1
into grub boot kernel parameters, Fn + Up/Down to change brigtness works on
my G360. It's no need to write a Udev rules like my previous method.
Hi,
I think I found a easy and least effect to the existed things' way for
adjusting intel_backlight using udev rules.
I noticed change action of backlight subsystem when I press Fn +
PgUp/PgDn on my lenovo G360 + 3.2 Kernel notebook. So I wrote a rules of

So, the next thing I'll try will be moving it back to the top.
That works, and I no longer think gnome-power-manager should
be changed, so I'm reassigning the bug.
Please change

I implemented this in the following patch. […]
many thanks for that.
Perhaps the upstream maintainer will eventually choose a different
solution; but until then, I think including this patch in the Debian
package would help VAIO
Package: gnome-power-manager
Version: 3.0.2-3
Severity: normal
On a Sony Vaio VPCYA1V9E laptop, if I press Fn+F5 or Fn+F6, then
gnome-power-manager attempts to change the brightness of the
display backlight, and shows a window as if it had worked.
However, the brightness does not change.
