Darn, can't edit posts. Won't make that mistake again!
So, what you said worked, but I have now progressed to my next roadblock. In the nVidia installer, now a new error message appears that reads:
"ERROR: You appear to be running an X server; please exit X before installing"
Then it tells me to check the readme. Well I did that, and consulted other threads regarding shutting down xfree86, but they are all far above my head.
Can someone help me with this, my next obstacle?
