I'm using RedHat 7.1 with the NVIDIA drivers, and am having trouble with the NeHe tutorials. The linux/glx ones work fine, but the linux ones that use glut give me this error:
"GLU fatal error in lesson04:visual with necessary capabilities not found"

Any ideas?
Thanks in advance....

Sorry the error is:
"GLUT fatal error in lesson04:visual with necessary capabilities not found"

That means the application tried to initialise a mode through glut, but that mode wasn't available (e.g., maybe it asked for a stencil buffer, but that isn't supported in your setup).

rts..you were right
I changed
// glutInitDisplayMode(GLUT_RGBA | GLUT_DOUBLE | GLUT_ALPHA | GLUT_DEPTH);
to
glutInitDisplayMode(GLUT_RGBA | GLUT_DOUBLE | GLUT_DEPTH);
and it worked.

I have a GeForce2 GTS...do the nvidia drivers not support the GLUT_ALPHA?

Yes, they probably do, but you are probably in a bad mode.

If you are in 16bpp, try 32. If you are in 32, try 16. Or it might be something else, but along these lines.

Sorry I can't be more specific, but I don't own an nvidia card.

rts - Youre right again...
I was in 16 and when I switched to 24 then Alpha worked....wooohoooo....
I'm comin off the Direct3D Bandwagon and movin to Linux....
