[orca-list] I've lost my default desktop and I don't know what to do

[Rusty Perez <rustys lists gmail com>]

Hi folks,
Yes, it's me again with my newby questions.
Last night I attempted to switch my default desk top.
I'm running a  system upgraded from ubuntu 12.10 to 13.04
Here's what I did:
I installed gnome-shell 3.6.3.1
I installed the gnome-shell-fallback
Then I logged out with the command
sudo gnome-shell-quit

I heard the ubuntu drums, but then i had no speech. I hit ctrl/s but
got no speech
I waited, tried again, and no speech.
So, I forced a shutdown.
then I rebooted the machine.
I heard the disk spinning, but after a sufficient amount of time, no
ubuntu drums.
I hit ctrl/s anyway with no result.

I forced a shut down again, and went to bed.

Any thoughts?
How can I regain speech and a desktop?

Thank you for your support! :-)


Thanks!
Rusty
