The open source nv driver lacks the hardware support which is held proprietary within nVidia, Inc. 
They do release and maintain their own linux driver which is a binary,
not "open source" and quite frankly a Devil's Bargain to use it. Of
course I use it as I want my hardware to work. It sure sounds like
something is enabled there on your machine, though. I guess you could
crank up adept manager and search on nvidia to see what you do have
installed. What I think you want to have is envyNG installed. It will
grab the best package for you and install it for you. Warning, it can be
fraught with peril at times, when it re-writes /etc/X11/xorg.conf file
and makes a mistake, so you will want to back it up first. If it blows
up, you need only copy the original file back to xorg.conf. 

Whoops, sorry I meant nv when I wrote xv, my old roots are showing.
Hopefully others will chime in with some advice to balance against my
own, just so you get it right the first time. Ric
