It seems that devicekit-power won't support the backlight, so I revert to HAL
use even if it's depreciated.
For those who wants backlight support in Karmic, here are the 3 modified files
(work in xubuntu 9.10).

Hi,
firstly, sorry for not debbugging the issue in Karmic (sony laptop used for
work), so this post is purely informative, but may help the debbuging
process.
To better understand we the bug should be here is some technical infos :

@ Steve,
It should a good thing to leave the sysfs path, but the thing is that nearly
everything vaio specific rely on the sony-laptop module. The issue here is
that the backlight device is created with a sysfs path for every viao (see
Here is a new version of
/usr/share/hal/fdi/policy/10osvendor/10-sony-laptop-brightness.fdi which
should work.
I just removed the linux.sysfs_path for all model to do the trick.
Can somebody test it ?
@Alex : Thanks a lot for your highlights
@benste :
I did not try on Karmic. Since I do not
I was hoping that I've done the trick. The issue is that the
10-laptop-panel-mgmt-policy.fdi is loaded before
10-sony-laptop-brightness.fdi (which delete the wrong sysfspath).
Thus There is two solutions :
1- force the evaluation of 10-sony-laptop-brightness.fdi before the other
by changing its
Maybe solution 1 : Could somebody try to move
/usr/share/hal/fdi/policy/10osvendor/10-sony-laptop-brightness.fdi

/usr/share/hal/fdi/preprobe/10osvendor/ ?
(obviously after moving it restart HAL or the computer)

Sorry guys,
I don't really understand why it is not working, but you have to uninstall
the previous version of the package first, or maybe the paths I use are only
for 64bits.
I'm sorry, but I don't have a lot of time to help you for now.
So, could you extract the package, and try to install
Yes, you're right .diff files are better.
It's just that I forgot to backup the previous files, so I cannot generate
them asap.
You'll here find there the 3 files that I modified.
their paths are /usr/lib/hal/scripts/linux and
/usr/share/hal/fdi/policy/10osvendor
Just diff them for me.

That package fixes the main issue for me - the hotkeys now control the
brightness. Thanks yleetiny.
However - I do not have 18 brightness levels when
Sorry guys, I thought the bug was already solved.
I made a quick fix. What differs from original distribution version is :
1- I only make 18 levels since for me smartdimmer goes from 15 to 100 with a
step of 5.
2- I removed the sysfspath of the backlight card (that sony-laptop wrongly
creates).
I reproduced this symptom with debug symbols installed but there is no
files generated in /var/crash so I don't think that a report from
apport was made.

Pulseaudio and gnome-power-manager crash when unplugging ac power while playing

I agree that submitting patches are the best way to solve a bug, and I was my
goal when I try to dig into the issue.

more likely an experimental support.

Your script is a great workaround, it compiles cvs, etc.. etc.. and it is

2- you have the sony-laptop module, correctly associated in hal : sony vaio

There is no need to a file to increase backlight since you only need to know
how to get and set the correct value.

Sorry I said a small mistake in my previous post : if the sony-laptop

The FN-keys for sony vaios are not linked to acpi, but linked to the

that there is no acpi event at all. Concerning the brigthness support
