Thanks for your response.
Yes, that works and I have that change made.
However, shouldn't that not be required?
I mean, if I install a package, didn't like it, and decide to purge it,
shouldn't things go back to normal?
It seems to me that my trying to get nouveau working caused some
unknown changes to the system and purging the package didn't undo that change.

Thanks,
