Getting X11 to work

I had some trouble getting X11 to work when I attached my USB drive to my work computer. I was getting weird colored snow instead of graphics. After trying many different things, I finally installed the proprietary nvidia drivers instead of the open-source driver called "nv". By refererring to this website, I was able to install these drivers quite easily:

I typed in the following instructions into a terminal window:

sudo apt-get install nvidia-glx linux-restricted-modules-$(uname -r)
sudo nvidia-glx-config enable 

It worked so I have X11 now.
