Hello all
I've just installed Debian in my Fujitsu T4010D laptop a few days ago.
Everything is going fine except that I can't change the screen brightness. I've tried everything (maybe not everything but you know what I mean :P) but I'm not having any success.
The problem is that my function key (FN) does not work so I'm not able to change the brightness.
I installed gddccontrol 0.4.2 but it says that my monitor does not support DDC/CI. So I googled for it and some advise to update the graphic drivers. The problem is that I can't update them either.
This is what the log shows when I try to install the drivers:

The DRI drivers can not be installed without the latest kernel modules.
Installation will be aborted. See the dri.log file for information on
what went wrong.
My graphics is an Intel 82852/82855.
So I did some more search and found some drivers for the FN key...but again...I can't install them. When I try to run the make file it just starts popping some errors.
I don't know what do to anymore and I'm a noob so...hope you guys can give me some help here. The brightness is too high...it hurts my eyes :S
Thanks in advance
Take care!

Bumping!
Doesn't anyone knows how to change the screen brightness?
Re: How to change screen brightness? (Debian + Fujitsu T4010D)
You don't need a driver for the FN key; It's controlled by firmware. At least it is on my laptop; I can use it before the OS loads. Maybe your BIOS settings need to be looked at.

I have a dual boot of windows and linux and FN it's working fine in windows.
How is it so difficult to change the brightness? :S
Re: How to change screen brightness? (Debian + Fujitsu T4010D)
hello !
did you install the headers of your kernel before you started to try to compile your drivers ?
It should be a package so called : linux-headers-your kernel version.deb
The compilation seems to be unable to find them. I you did install the headers and still have this problem, It might come from the version of your drivers to find another one...
good luck :)

Re: How to change screen brightness? (Debian + Fujitsu T4010D)
Yes I have them installed. Thanks anyway.
When I start the package manager, it asks me for the root password. When this happens the screen gets darker, so there must be a way to get a lower brightness I suppose.
Thanks
