Does a laptop with a GPU also use IGP?

I have a Thinkpad T60 with dual screen setup:

  1. The laptop's LCD: Is normal looking.
  2. VGA external monitor: Looks "wavy," but I hooked it up to another computer and it looked fine.

Does this imply my GPU is connected to the VGA-out and the built-in LCD is driven by IGP? Is this typically how a laptop with one GPU works? Thanks.
