Backlight class isn't present

Scampada:
Hi,

I was trying to find something in /sys/class/backlight to be able to change my screen brightness from CLI... But there is nothing. I put a boot laptop option, still no effect. Why? Is it something I have to tune inside my TC?

Scampada:
Output from modprobe -l | grep backlight shows:

Looks like I have even unnecessary ones but there is only an empty /sys/class/backlight directory.

curaga:
Are you sure your hardware can do that? Anything there on another distro?

Scampada:
Yeah, sure. It's all OK under openSUSE, even brightness buttons are working fine. I found that in openSUSE there are two or three more kernel modules in
/lib/modules/$(uname -r)/kernel/drivers/video/backlight - gpio_backlight & pwm.bl. But it's not able to just copy them to TC, though. A pity.

What can I do?

My board is a netbook of 'Packard Bell dot s' series

Scampada:
I can upgrade and rebuild the kernel, but... but... ohshi~

Are there TC 3.17.* kernel sources available? Does it depend strictly whether it's a TC kernel source or not? Can I manually compose a new TC compatible kernel source and build it?
