Bugfix/nvidia update

[cbames]

When I attempted to use the nvidia patch it wouldn't install xserver because of some updates that ubuntu made to the versions available. Thus I added apt-get update so that a proper install could be made.

Combine the update and install line and I'll ask to merge.

Thanks for pointing out the best practices websites. I'll make sure to check those out. I've pushed your request, so it should be ready now.
