"Linux Mint 15 is the most ambitious release since the start of the project. MATE 1.6 is greatly improved and Cinnamon 1.8 offers a ton of new features, including a screensaver and a unified control center."
Really, linux mint, a screensaver, really?
Well, the last time I tried Ubuntu 3d screensavers wouldn't work properly, meaning the screen went black and I had to enter my password with no visual feedback to unlock. Also the screensavers weren't configurable and were generally an example of all that was wrong with ubuntu, linux and everything.
