Nvidia GPUs & Linux

A couple more non-link-dump link dumps:

1. Ubuntu Nvidia binary driver howto, which has some troubleshooting info
2. Using integrated graphics for display, albeit with a laptop; I ran into the login loop, and found elsewhere driver installation via PPA

This is tricky stuff.  Lots of compatibility problems, disinformation, and apathy, and money hangs in the balance.  Mining definitely isn't for everyone.  I'm not sure I'd do it again if I could go back--but I'm kind of committed now, at least until I recoup the hardware costs.
