Need to change drivers

[Jon Anderson]

This is the problem I run" lspci -v" which checks all drivers on my 
system and more. It says kernel driver in use: nouveau
then under that it says kernel modules: nvidia 
recent,nvidia-96,nouveau,nvidiafb
So what it looks like I have 3-4 drivers for my video card loaded and 
one, nouveau, being used. I think they conflict with each other. I'm 
trying to add drivers other then nouveau, because the mouse freezes with 
nouveau. At this point I can't seem to get rid of nouveau, I go to 
terminal and type"sudo apt-get --purge remove 
xserver-xorg-video-nouveau" and it says that it's not loaded so I can't 
dump it. "lspci-v" says nouveau is the driver being used and trying to 
dump it it says it isn't installed. ?????????confused. I want to dump 
nouveau, what should I do? I also go into Synaptic package manager and 
it isn't listed as being installed. All help exepted!
