It's Ubuntu Netbook Remix 10.04, Lucid Lynx.
It was something to do during a tranquil weekend while sipping a beer. The new Ambiance and Radiance desktop themes are very pleasing. Another nice thing (not new) about Ubuntu Netbook Remix (now known as Ubuntu Netbook Edition) is a desktop daemon called Maximus which automatically maximizes and un-decorates windows, thus saving space on a small netbook screen. You gotta love anything with the name "Maximus." 😀
As usual, it runs like a dream. :up:
