If it didn't work properly that's a bug that should (have been)
reported to NVIDIA.

I guess I don't understand why that's preferably behavior.  If you
don't have the nvidia driver installed at boot time, then you're going
to end up with poor performance regardless.  And I've seen many
reports of people who ended up with their system falling back to the
'nv' driver, they were unaware of it, and complained about poor
performance.  So the sword cuts both ways.  Its only good if you
understand what's happening, and in that case, wouldn't it be better
to just install the nvidia driver?

I suppose, but I don't see what's so hard about installing the driver.
 Its not like its difficult or even time consuming.

That's fine.  I appreciate your feedback.
