You will need to setup the nvidia drivers from dell. This will require editing your /etc/xorg.conf. I am using dell-nvidia-7664-3dkms.x86_64.rpm. These are for RHEL4, which should be pretty much exactly the same as CentOS. You will add the line ' Load "glx"' and comment out (#) the Load "dri" line. I also pasted the Device section, which you will see you will need to change the driver line to "nvidia"

Section "Module" Load "dbe" Load "extmod" Load "fbdevhw" Load "glx" Load "record" Load "freetype" Load "type1" # Load "dri" #direct rendering interface - NVIDIA uses OpenGL not DRI" EndSection

Section "Device" Identifier "Videocard0" Driver "nvidia" VendorName "NVIDIA" BoardName "Quadro FX 1400" Option "TwinView" Option "TwinViewOrientation" "LeftOf" Option "MetaModes" "1280x1024,1280x1024; 1024x768,1024x768" # Option "ConnectedMonitor" "DFP,DFP" Option "SecondMonitorHorizSync" "30-80" Option "SecondMonitorVertRefresh" "56-76"

EndSection

Hello all

I am just starting to use freesurfer in our new laboratory of functional neuroscience. I have a Dell machine with 64 bits Intel Dual Xeon processors. I have installed the 64 bits Linux Centos 4 Operating System. Also the machine has an nVidia Quadro FX 4500 graphic card.

I have installed freesurfer for x86-64 Centos 4 successfully but when I run the command: tkmedit bert orig.mgz

I got this message displayed in the prompt:

freeglut (tkmedit): OpenGL GLX extension not supported by display ':0.0'

I was using the GNOME 2.7.3 Terminal, Copyright © 2002 Havoc Pennington

I will appreciate any help to overcome this problem

In advance Thank you
