"Since gNewSense doesn't use proprietary drivers, and since the
open source free versions don't have any 3d power, you won't be
able to run things like Compiz and some of the other extreme
eyecandy systems. Understand that this is not going to always
remain true. If you're using an ATI, Via, or Intel card, if you
don't already have elementary 3d support, you soon will."
