"Ubuntu Post-Installation Questions
Q: Ok, I got Ubuntu installed, but I have Nvidia graphics and the
drivers didn't load properly. Now what? (This question could be
slightly altered in any number of ways, but the bottom line is that
if you are having issues with Nvidia video, it's a common problem,
and yes, there are solutions).
A: Nvidia uses a restricted set of drivers (as in "not open"), so
you'll have to allow Ubuntu to use these restricted drivers. This
is where you dive into the world of repositories. And while we are
adding the appropriate restricted drivers repository so that you
can use the Nvidia drivers, we'll go ahead and make sure you have a
few other repositories added (assuming you want the extra apps and
goodies that are available in 3rd-party repositories). (And unless
you are a purist freak, you probably do). (j/k on the "freak"
