So according to http://ubuntuforums.org/showthread.php?t=282248, my Radeon Mobility is actually not doing 3D hardware acceleration - this seems to be the cause of my issues with Panda3D samples using hardware acceleration (which is all of them) not working.

However, I have the ATI prop. drivers enabled, and glxgears goes at a clippy framerate - so I'm not quite sure what to do from here.

Help?
