SDL_GL and Xfree4.0

When I try to run testgl I get the error

Xlib: extension “GLX” missing on display “:0.0”.
Couldn’t set GL mode: could not determine glx visual info

Any ideas how to fix this? I just installed Xfree4.0, all the other sdl apps
work find except the GL ones.

Xfree86 4.0, much unlike all previous releases, comes with a real glx implementation.
Currently, only drivers for the voodoo3/banshee cards is available.

The standalone has a fake glx implementation. - the one that comes with 4.0 does not.

Thus your error message. Either make sure that the old mesa library is used and not the
one that comes with 4.0 or wait for real GL drivers for your card.

How do I get SDL to use the old Mesa libraries I was using before?

Either use LD_LIBRARY_PATH or make sure that the directory the old mesa libraries are
is listed before the one containing the XFree86 one (/etc/ld.so.conf).--------------------------------------------------------------

Actually I found that putting the line “load GLX” (Im not sure if that
is the exact line) into the XF86Config file allows the SDL GL apps to work.
But it seems slower than before when I used the Mesa libraries.
