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:
BoardName “GeForce Go 6150”
And that’s the begin of my /etc/sysconfig/displaymanager:
*@linux-turion64:~> cat /etc/sysconfig/displaymanager
Path: Desktop/Display manager
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.
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.
