   When I launch Gnome 3.0, I get my background screen, then nothing.
On one occasion, I got distracted, and when I looked, I found I was in
the fallback screen with a message telling me that I needed 3D
acceleration.

   I don't know.  I have been running XFCE a bit.  It has locked down
my login screen so that if I want to run anything else, I must
deliberately select it.  The run-whatever-I-ran-last-time feature is
disabled.  Once, a long time ago, I tried out XFCE, and it screwed up
my Gnome settings.  On the whole, XFCE is a nice window manager, but I
am suspicious.

   I am trying to install updates.  I am running kpackagekit.  It says
I have 779 updates pending.  When I try to install them all, I get an
error message "An error occurred while running the transaction.  More
information is available in the detailed report."  The detailed report
identifies the offending package.  If I delete that from the list, I
get another offending package.  It looks like I can do updates one at a
time.  Nine at a time seems to have worked.

   Every bit helps. I am probably going to have re-install this thing,
but it would be nice to know what I did wrong.
