Downloaded, burned, and booted into Ubuntu 7.10 alpha 5 just to kick the virtual tires. Impressed over all with the quality of this alpha release, and I can see (and appreciate) where Canonical is going with Ubuntu. Looks like lots of work under the hood, with subtle but very important changes to the desktop. Tools are also beginning to show maturity. I am truly glad that there is now an Appearance Preferences application that combines Theme, Background, Fonts, Interface, and Desktop Effects all in one spot. After using it for five minutes all I can say is why did it take so long? It might seem insignificant but it sure helps to quickly tweak and tune the look of the desktop.

The screen shot above shows both promise and a problem.

I recently re-installed my machine using the latest Ubuntu 7.10 alpha “Tribe 5″. There are some things that I thought the public would like to hear about, and also a few bugs I found and submitted.
