Ok, on what I had forgotten I saw on Unity, yes on the file, edit and
so on at the top of the panel. That confused me also, made me wonder
what application I had brought up to work in, thinking I hadn't that I
knew of, then I found the way to take Linux down from there.
I never did find out how to get into the System Administration to
set up the update manager, or to use Synaptic Manager. I didn't use
11.10 very long before I decided to go back to 10.04.
Unfortunately on the reload of 10.04 and then bringing it up to date
somehow the internal wifi got confused and would only work about 1 out
of 4 restarts and the audio wouldn't work at all. So I am now back to
Mint 11. Where the networking connects faster and the audio works on
the internal speakers, but doesn't work on headphones. I have found
any distro that will work on the switching of audio from internal
speakers to headphones for this PC, so I have one of those USB sound
cards to use for use with headphones.

I hope you get used to Unity. If my hardware worked better
with Ubuntu, by that the networking/audio issues, I think I would have
stuck with it too. I will try out 12.04 when it gets released soon just
to see though.
