Of course the first. I thought this was well known. For example, on an ASUS N53S:

Code:
knoppix@Microknoppix:~$ lspci
00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09)
.....
01:00.0 VGA compatible controller: NVIDIA Corporation GF108 [GeForce GT 540M] (rev a1)
It's an integrated Intel graphics controller plus a GeForce GT 540M card. The setup is very nice for someone, like me, who just wants to run Linux with as little fuzz as possible, and is content with eventually tackling performance problems as they appear. And I always check out the latest versions when there are problems, eventually update driver packages etc. Very, very often, hardware problems have been resolved in the next release.

Which it doesn't seem like you have done.

Since my desktop had no problem with nvidia card with the Knoppix DVD, I did not assume my laptop, which also has an nvidia card, will have a problem with the same DVD.
This kind of reasoning is, IMHO, just to ask for problems when you use Nvidia.
