I think I've seen this:

glxinfo | grep direct

as one way to tell.  xdpyinfo spits out a lot of stuff.  I think GLX is 
the extension you need.  (as well as NV-GLX for nvidia chips).

can you run glxgears?

Setting it up depends on the card you have.  With nvidia you need to 
download the drivers from nvidia, and it does the rest, sets everything 
up.  Not sure with other cards.
