From Jaunty to Karmic

I've upgraded my work desktop from Ubuntu 9.04 (Jaunty Jackalope) to 9.1 (Karmic Koala.)  Here are a few observations.

• The Nvidia bug that caused the pointer bitmap to fragment at certain screen locations has been fixed.
• Audio is back to both the headphones and speakers working simultaneously (true in Intrepid, mutually exclusive in Jaunty.)  I'm not sure if this is a design feature or a bug.
• Desktop panels jumped from primary (left) monitor to secondary (right) monitor.  I was able to move them back by deselecting "Expand" in the panel preferences, dragging the panel back to the left monitor and then re-selecting "Expand."
• I was having some issues with Sun Virtualbox (not OSE) where the app would grab the keyboard and not let go.  This let ctrl-alt-del work in the XP environment, but made everything else useless.  I did a full cold boot of Ubuntu and for no discernible reason it works fine now.

For anyone who does any development work for Unix servers, I am beyond praise for Ubuntu/Eclipse.  I have a better development system than I've ever had before with hardly a difference between my desktop and the production server in term of code workings.
