I am searching for a solution to set the backlight from a device, which uses the Intel Poulsbo Chipset.
The device is an "o2 Joggler", something like a better digital picture frame.
The display used is a:
“Sharp LQ070Y3LG4A LCD panel via LVDS port on Poulsbo”.
The device comes with a sch.ko module which is working for the original kernel 2.6.24-lpia.
It provides /proc/blctrl and can be easy modified by
echo VALUE > /proc/blctrl.
As the vendor (OpenPeak) doesn't offer any sources, I wonder how I can control backlight with other kernels?
I have running kernel 2.6.30 for now but as I have no sources for controlling the backlight - I don't get further.
Is there a general functioning source code to control the backlight from these chipsets?
I am using xbacklight program with my US15W netbook. Something like "xbacklight -set VALUE"
