This thread is about having 1 CRT/analog monitor and 1 DVI LCD monitor hooked up. The problem is the nvidia linux driver uses the analog as the primary display no matter what when using Twinview. If we could all afford two DVI LCD's then there wouldn't be a problem.
We have no access to nvidia's bug database, but I'm guessing this one was marked WONTFIX.
