checking drivers in ubuntu 10.10 for Nvidia 6600gt. I get this printout in terminal
 

01:00.0 VGA compatible controller [0300]: nVidia Corporation NV43 [GeForce 6600 GT] [10de:00f1] (rev a2)
Kernel driver in use: nouveau
Kernel modules: nvidia-96, nouveau, nvidiafb

So it looks like I'm using Nouveau driver but I have three drivers loaded Nvidia 96, which I believe is the 96.43.19, nouveau (the one I think it's using) and Is the nvidia fb mean it is a nvidia fbcon and is that another driver or what?
The point is I've been trying to test all the nvidia 6600gt drivers I can find the 173 the 96 and I'm trying to put in 260.19.36 but I haven't been able to get it in yet.and I believe that the nouveau drivers was installed from Ubuntu 10.10 when I put the 6600gt card in the computer. With all those three drivers listed as kernel modules could or do I have a conflict. And the reason I'm doing this is, the drivers that I have now are freezing the system.
