| | ====== This Is Different! I Fear Change! Make It Go Back! ====== |
| | |
| | The older Ubuntu desktop looked like this: |
| | |
| | {{:ubuntu-11.04-desktop-intro-001.png?300|}} |
| | |
| | The new one looks very different. What happened!?!? |
| | |
| | For the last several years Canonical, makers of Ubuntu, had their sights set on carving out a piece of the Internet of Things pie. They wanted to produce Ubuntu phones, tablets, and televisions in addition to servers, workstations, and laptops. And to power it all, they wanted a single, simple, consistent user interface. That's why they created the Unity desktop (pictured above). But now things have changed. Canonical has conceded that between Apple and Android, their target market is pretty much sewn up tight. It just takes way too much effort for far too little return on investment. So Canonical has moved back to doing what they do best: Servers, workstations, and laptops. (And clouds. Lots of clouds.) In this transition, Canonical decided to stop spending effort on developing and maintaining a desktop environment when there were already many nice desktop environments already available to choose from. |
| | |
| | The Unity desktop has been adopted by a third-party that intends to keep it under development. But I've learned not to trust the first run of any product, so I've chosen to go with a desktop environment that's maturely developed and main-stream in it's popularity while still being light and responsive. |

| | |
| | The great thing about Linux is it's modularity and the fact that it's infinitely customizable. You can change nearly everything about the look and feel of your desktop just by playing around with the settings. In fact, you can make it look and behave a lot like the old Unity if you really want to. The following is the same desktop, but with the elements rearranged to look like Unity. The transformation took less than 10 minutes. |

| | Right-clicking on elements of the screen will bring up menus where you can add, delete, move, swap, and tweak to your heart's content. Lots of behavioral changes can be made through the settings menu. |
