I set up Ubuntu desktop machines for nonLinux personnel and I do not have
these issues.  I do not recommend Ubuntu for a lot of server applications,
at least not yet.  Forgive me if I am wrong but it sounds like Jeff is
setting up a desktop system on a tower with a hard wire connection.

There is usually more involved with wireless and/or laptops then there is
with hard wire and/or desktops.  In most cases, due to the variety of
compatibility issues that arise in laptop technology, laptops tend to be the
most work.  Assuming that you have compatibility worked out, NetworkManager
usually works fine for most cards.  The issue I tend to run into is with
wpa2 enterprise auth servers.

I have not had the issue with static IPs like David, however, I usually
don't use Network Manager on my own machines, I tend to set things up
manually at home and turn off or uninstall Network Manager.  The exception
is with Laptops that go to and from campus.  With all of these issues at
once, I wonder if the problem is with compatibility and if you are missing
drivers.  CTRL+ATL+BACKSPACE and CTRL+ATL+F1  has always work for me unless
the keyboard is setup incorrectly in X.

For workstations, I like to install the server edition and install the X,
applications, kernel modules and drivers as I need them.

The network not managed usually means you have set things up manually.

What kind of Video card are you using...make, model?
