Lenovo ThinkPad W530 Xorg issue - Nvidia no display

[Kazuo Kuroi]

I need some help with my Xorg configuration on my W530. Currently, I'm 
facing an issue where if I set the laptop, Optimus off, to use the Intel 
card, then the X -configure generated xorg.conf, it works fine. But if I 
enable the K1000M Quadro, using either the X -configure xorg.conf or the 
nvidia-xconfig xorg.conf, I cannot get X to work properly.

Here's my Intel xorg.conf (the one that works):

My Nvidia xorg.conf (the one that will NOT work):

If I need to provide the logs I can... but there wasn't any errors to be 
had there. When running the Nvidia card, I just get a black screen with 
the grey block cursor in the lefthand corner. I'm guessing I'm just 
doing something dumb in the xorg.conf file.

Some insight would be appreciated.
