[vtkusers] Re: Xlib: extension "XFree86-DRI" missing on display ":0.0"

If you install NVidia drivers, like I did, from NVidia.com, you don't need dri.
It should be commented of your XFree86 config file.
I have a Dell system, but I don't get my nvidia libs from Dell.  I have always gotten them from NVidia.

Do you have a copy of the opengl libs somewhere that your app happened to pick up before the nvidia ones?

Or, if you don't use the nvidia drivers, and want to use the ones that come with Redhat, you should check that
dri is loaded in your XFree86 config file.

Hi all,

My platform : RedHat Enterprise Linux version 3 release: 4.3.0-62.EL running
on a Dell Precision 650 with dual Xeon processors and NVIDIA Quadro FX 3000
video card. XFree86 version is 4.3.0 .

My problem : I think direct rendering may not be working. For example when
I run one of the examples under VolumeRendering, the rendering works but I
get the following message -
Xlib: extension "XFree86-DRI" missing on display ":0.0".

A similar problem was posted before but I think it was not resolved.
This is the url :

I hope someone will be able to help me with this.
Thanks in advance.
Sambit.
