Xorg 1.8 and nvidia backlight

Hi everybody,

I hope this is the right place to ask, I posted here and not in testing since Xorg moved to extra and I updated from there.

I own a Sony Vaio S series laptop, and I was able to control the screen's brightness by installing the nvidia-bl module from AUR and loading it with options max_level=130944 shift=7.

Furthermore, in order to let gnome to work with the Fn key, I had to use the following HAL preprobe rule to disable the other brightness settings:

alessandro@alessandro-lappy:~$ sudo cat /etc/hal/fdi/preprobe/sony.fdi 
Password: 
<?xml version="1.0" encoding="UTF-8"?>

<deviceinfo version="0.2">

<device>
<!-- Ignore backlight interface created by sony_laptop
-->
<match key="linux.sysfs_path" string="/sys/devices/virtual/backlight/acpi_video0">
<merge key="info.ignore" type="bool">true</merge>
</match>
</device>
</deviceinfo>

However, I have no idea how to achieve the same effect with Xorg 1.8 without HAL. I googled this stuff and found nothing.
Thanks in advance for any help .
Cheers,
Alessandro

While i don't know the answer to your question, why don't you just keep hal installed to use your previous setup?

That is something I might do. However, since HAL is going to be deprecated and this one is the only issue preventing me from getting rid of it, I would like to see if there is a way to solve it.

Thanks a lot for your kind answer,
Alessandro
