How can I disable graphic switching MacBook Pro...

There must be a way by removing some files from the system to stop the graphic switching taking place.

Does anyone know which files need removing and how to go about it? Apparently it could be done in "console Mode".

The MacBook Pro 2010 has 2 graphic options: the inbuilt Intel Which works perfectly and a dedicated Nvidia GeForce GT330M which has some faulty soldering issues. The computer switches on one or the other depending on graphic needs. There is a workaround using a program called "GFX card status" which enables to use the integrated card, unfortunately every so often an application will make it switch back the GeForce, giving the well known "black screen of death".
