I have GeForce 2 Titanium
and I run the testgl.c file from SDL.
but I got that:
SDL_GL_MULTISAMPLEBUFFERS: requested 1, got 1
SDL_GL_MULTISAMPLESAMPLES: requested 2, got 1
Why?

Maybe you have disabled antialiasing in the driver?
Are you sure the gf2 supports aa?

My guess would be that it only supports 1 multisample buffer.
Depending on your OS get either glxinfo(linux/UNIX) or glinfo(Windows)
and run it. It will tell you about the number of multisample buffers
that are supported by each visual.

Because Geforce 1&2 don’t support multisample buffers, you need at least
a geforce 3 for that. With your geforce 2 you can have FSAA using
something called superbuffers (this is does not work the same as
multisample buffers; although the purpose is the same), but SDL has no
support for that.
Oh, and as far as I can tell, under linux the driver exposes no api to
enable/disable superbuffers, except using the infamous env variable
(export __GL_FSAA_MODE=4 for example).
