Thanks Camaleón,
I am trying to stay away from anything closed source, and I believe that I have
the latest nouveau drivers installed as I am running a newly compiled 3.5.1
kernel. I would assume the tarball contained the latest drivers. lsmod shows no
fb anything. But you have pointed out a clue that I overlooked.
I will certainly check out the links. I will update y'all with the results, but
I may
have to put this off until middle of next week. We are doing beta-testing of
some
apps here and things are starting to get hectic.
Nelson
