Hi,

which NVidia modules did you load? With the latest driver you have to
load nvidia.ko and nvidia-modeset.ko in order for X to work. You also
have to really make sure that in your BIOS the graphics adapter
"discrete" (or similar) is selected.

And you might have to set the BusID in the xorg.conf. I cannot remember,
if I had this set or not on the W530. Try without first. I think this
was only necessary on Optimus-only systems to make sure the Intel is used.

Cheers,
Stefan.
