NVIDIA GeForce Go 6150 Brightness problem

Hello all,

I am using an HP Pavillion laptop with AMD Turion 64.

My system is a dual boot Windows-Vista/OpenSUSE-10.3.

Brightness controls works perfectly under Vista, but they are dead under OpenSUSE.

If I try to use nvidia-setting, I get the following answer:

You do not appear to be using the NVIDIA X driver. Please edit your X configuration file (just run nvidia-xconfig as root), and restart the X server.

But the /etc/X11/xorg.conf it’s correct for this driver:
Section “Device”
BoardName “GeForce Go 6150”
BusID “0:5:0”
Driver “nvidia”
Identifier “Device[0]”
VendorName “NVIDIA”
EndSection

And that’s the begin of my /etc/sysconfig/displaymanager:
*@linux-turion64:~> cat /etc/sysconfig/displaymanager

Path: Desktop/Display manager

Type: string(Xorg,Xgl)

Default: “Xorg”

Xgl is an experimental Xserver using OpenGL for rendering.

Right now only the glx backend is supported, which runs on top of a

standard Xorg server providing OpenGL.

Set this to ‘Xgl’ and run SuSEconfig only if you want to run your

displaymanager (kdm/gdm/xdm) on Xgl on top of Xorg.

This setting is case sensitive.

Warning! This is highly experimental.

DISPLAYMANAGER_XSERVER=Xgl*

As additional notes: I use compiz and I have enabled Desktop effects but I have disabled 3D Windows.

All the brightness applets I tried are worthless.

TKS for your attention.
