What kinds of desktop environments or shells are there for Ubuntu users to install?
Please list one desktop environment or shell per post with:
- a description on why you like or suggest it (features, performance, etc.),
- a good screenshot, preferably of it running on Ubuntu and showing off some of its features,
- the minimal requirements required for it to be usable, If there is any setting to lower it's requirements(Like kde's low-fat profile), please mention how to enable said setting
- some instructions on how to set it up, if in the repositories, please provide a software centre link
