[expert] Switching to X 4.0

[Chris Spencer]

Hello,

I recently reinstalled Mandrake 7.1 and, like a lunkhead, I forgot to set
things up to run XFree 4.0. So right now I am running 3.3.6.

I know that there is a file somewhere that I can edit so that I can run 4.0
instead of 3.3.6. However I forget what the file is. :( Can someone please
refresh my memory? Thanks...
