Donna, It appears you need the TNT2 NVIDIA driver, which should work for the chipset you have. Your computer checks the hardware and thinks its either RIVA or TNT2. You have some kind of driver already or you couldn't see anything on the screen, but it does not support GLX. You may be able to simply install the driver, or you may have to rebuild the Linux kernal which I believe is also described in the NVIDIA section about drivers. To install the Nvidia driver go to http://www.nvidia.com/content/drivers/drivers.asp and choose Graphics Drivers->GeForce and TNT2 ->Linux IA32 (Intel architecture 32 bit)->Go and follow the instructions to install it. Do let me know if this helps! WE are trying to make the IDV work on all Linux systems so your help and patience with this matter is very much appreciated.
