If that works, do it like that. It sounds like there's some display detection going on at login that doesn't identify a projector properly.
I would also guess that you might only need a generic display profile for all projectors as in my experience they all have similar attributes. I would also look at how your laptop handles displays. Most laptops would have a switch between LCD and CRT, which is usually an alt function of one of the function keys. Something is telling me that Thinkpads have an auto switching display option in the BIOS which you might need to turn off. I don't know why it could be the case but it seems possible with the changes to hardware detection in Karmic.
