How to change screen brightness? (Debian + Fujitsu T4010D)
 
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:

Code:

This appears in the terminal:

Code:

Compiling new agpgart module...

ERROR: AGPGART module did not compile

Compiling DRM module...

ERROR: Kernel modules did not compile

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!

Welcome to LQ! :)

A couple questions: If you boot an Ubuntu 7.10 CD does the screen brightness function work? Also, I assume you've Googled about Linux support for your laptop - so did anyone else with the same laptop get it working? I'm just trying to determine if whatever hardware takes care of this is Linux-supported or not.

EDIT:

Can you post a link to the relevant Web page?

I guess. At least I think they installed the buttons drivers successfully.

The drivers are available for download at:
http://sourceforge.net/projects/fjbtndrv

I found them here:

Thanks again! :)
Take care.

Bumping!

Doesn't anyone knows how to change the screen brightness?

Buttpt 02-28-2008 12:39 PM

Bumping again...still with the same problem.
Sorry for the bumps but I am trying to make people to see this topic instead of creating a new one.
