I installed XP on my MacBook Pro using bootcamp. Now when I boot into OS X it looks like everthing is in like 16 color or 256 color. The display looks horrible. Even the window that displays when OS X is booting (with the apple logo) looks messed up. I must have done something wrong. It looks like the XP installation has somehow tried to replace my video driver. How do I fix? I really don't want to have to rebuild my laptop.
