What do you mean with software or native? The same as indirect or direct?
The same as accelerated or not accelerated?

What do I have to look for in the output of glxinfo?
With my Xgl, glxinfo says:
...
direct rendering: No
...
OpenGL renderer string: Mesa GLX Indirect
...

I know the driver I am using (radeon open source) doesn't support
FBO or pbuffers.
