Upgrade Pogo2003 from Ubuntu 11.10 to 12.04 LTS

My AT&T DSL was running at its peak data rate today -- 80 KB/s (yeah, I know that's slow and I'm not bragging about it, but it's cheap) -- so I decided it would be a good time to upgrade my older linux box Pogo2003 to Ubuntu 12.04 LTS. The complete upgrade took about 5 hours but was uneventful. So far, the installation appears to be successful.

My new desktop under 12.04 appears to be the full 2D matrix of workspaces with both right/left and up/down workspace changes. However, I don't think the installation is the full Unity desktop. Maybe it's not Unity at all -- I don't know how to verify this. I do have the launcher, which I did not under 11.04. In any case, it's much better than 11.10, under which I only had linear workspaces (no up/down workspace changes).

The only major deficiency on the machine, which was present under 11.04 and 11.10, is that certain videos won't play under any of the three browsers (Opera, Firefox, and Chrome) using Adobe Flash Player. I was hoping that going to 12.04 LTS would fix that. So I still have that problem to resolve.
