stereo view using Opengl on Linux

I tried the sample program pulsar.c to create a stereo view, when I run it, it said:
GLUT: FATAL ERROR IN STEREO: visual with necessary capabilities not found

what does it mean? what shall I do?

thanks

It means that you do not have visuals with support for quad-buffered stereo. Quad-buffered stereo is not supported by the NVIDIA drivers. You could either look at the drivers from Xi Graphics (www.xigraphics.com) or do passive stereo.

I am using Radeon VE card, it doenot support quad buffering, so I have to use divided stereo, right? how can I use GLUT to implement it? or do I need to use other library?

Thanks in advance!
