FYI
Found the solution to the problem...for anyone struggling with the same problem on a Sony Vaio.
My Vaio"VGN-NW240F" Has a proprietary Sony service that conflicts with the display
driver and does not allow the display
driver to save settings permanently...they will reset on log-off or re-boot producing a very pink looking hue. Disable "Vaio Event Service" and then the problem will be resolved. The side affect is you loose function keys that dim and brighten the display, but a simple desktop gadget can then be used to replace the keys.
The service is = "Vaio Event Service"
