Default Re: Backlight/Brightness control not working

Hi, you can try set backlight over hal:

first set
Code:
Option          "RegistryDwords" "EnableBrightnessControl=1"
in xorg.conf

then in file /usr/share/hal/fdi/information/10freedesktop/10-laptop-panel-hardware.fdi add this code:

Code:
<match key="/org/freedesktop/Hal/devices/computer:system.hardware.vendor" string="Sony Corporation">
  <match key="/org/freedesktop/Hal/devices/computer:system.hardware.product" contains_outof="VPCF11M1E">
          <merge key="laptop_panel.brightness_in_hardware" type="bool">false</merge>
  </match>
</match>
Values of system.hardware.{vendor,product} you can detect with:
Code:
lshal | grep system.hardware.vendor
lshal | grep system.hardware.product
that's working for me
