Accident, deleted .config

[Bob Goodwin]

        I managed to delete .config which takes out a large group of
        directories. I can boot the computer but can't run X.

        I am about to re-install F-14 out of desperation unless someone
        knows a way to repair the damage. It will be a few weeks before
        F-15  will be available and I would like to keep that computer
        working until then.

        Any suggestion, what to do next?

        Bob
