Dell D630 - libsmbios and dcdbas

Hi there,

I want to use the Dell utilities of libsmbios. I installed the package, but some tools (like propertyTag) give an error saying that the module "dcdbas" is not loaded.

Can anyone help me finding that module? It seems like the automatic backlight is not working because the lack of this driver. The backlight of my laptop has some ambientlight sensor that controls the brightness of my display depending on the light in the room. Omforunately it doesn't seems to work.

I'm using the 64bit-version of Archlinux.

Regards,

Ibex

dcdbas module should be installed with kernel. try

modprobe dcdbas

If it loads ok, add it to the MODULES section in your rc.conf

FATAL: Module dcdbas not found.

That is the weird one. On the docs on internet that I've found, everybody seems to have dcdbas out of the box. They just have to load the module. But here, I cannot find it on my computer.

I've tried to updatedb and then locate dcdbas, but I've got no results. Even find / -name '*dcdbas*' gives nothing. Maybe something else I can try?

It's a kernel module. It might be built-in

grep DCD /usr/src/linux/.config
CONFIG_DCDBAS=y

That's with my custom kernel.

I also have a custom kernel but I'm on a D630, but even without the module loaded, if i hit function + left arrow (Has the word auto on it in blue) then it uses the ambient light sensors.
