NVidia driver beta problem

[mdovell at comcast.net]

I stupidly installed a beta driver and now I get a command prompt that keeps blinking. 
GRUB loads (I'm using 9.10) and I get the logo and then it goes to a blinking/flashing command prompt for my login. 
After logging in I'm still at the command prompt. 
Is there a way to roll the driver back or should I reinstall?
