Thanks, everyone, for all this help!
So,
I found that the package 'nvidi-glx' and it's associates were not installed, so I installed them. Now, when I enter 'glxinfo,' I receive the following:

I do not have a file xorg.conf on my system.
lsmod | grep nvidia returns nothing.
I get the same error upon trying to run secondlife, namely it asks me to set screen display to 32-bit.
Any more ideas?
