The problem is that your trying to throw a band-aid over a driver problem. On my laptop, this problem doesn't show up, using a Mobility Radeon 9000. I would recommend that you see if there are updated drivers before going through all this. Both ATI (AMD now) and nVidia drivers both come with desktop manager software now that takes care of this.
